The performance requirements of horizontal three phase separators have experienced a strong development in the past decade. This resulted from increasingly challenging separation duties, i.e. on FPSO‘s. ASCOM separator designs stand out for two reasons: 1) sophisticated dynamic CFD simulation design methods are routinely used to optimise the use of available space in the vessel; 2) proprietary state-of-the-art separation internals are applied with unmatched performance characteristics. New build and revamp The Ascom design methodology can easily be applied to improve the performance of existing separators. All internals can be installed through manways. Overall design methodology Ascom separators are designed so that upon entry the fluids are efficiently pre-separated into a gas and liquid phase. These two flows then are carefully distributed over the gas and liquid section of the separator. This is achieved by the inlet device, a critical component of the separator, and by using Computational Fluid Dynamics(CFD)design methods to optimise the flow path of the two fluid phases.

Oil / water separation The even distribution of the liquid phase is achieved through the use of customised distribution baffles, which can also mitigate any occurring wave motion. The application of an ASCOM HiPer coalescer plate pack can further enhance the oil/water separation performance of the separator.

Gas / liquid separation The bulk of the gas/liquid separation takes place in and directly downstream of the inlet device. ASCOM offers a full range of different inlet devices, ranging from vane type inlet devices to the powerful HiPer inlet cyclones to take on any challenge. Downstream of the gravity separation section the proprietary ASCOM demisting internals will guarantee the removal of any remaining fine liquids.

Summary The advantages of ASCOM separators / HiPer separation internals are: • Minimum separator size • Maximum overall liquid separation efficiency

from gas, • Maximum oil from water and water from oil

separation efficiency, • Less sensitive to any wave motion of FPSO‘s • Excellent turndown characteristics, • Low pressure drop, • Clean & fouling service possible, • No maintenance due to robust design, • Installation through manway, • No welding required for installation, • Easily replaces existing older internals.

Improving the gas / liquid separation efficiency of vertical separators (‗Scrubbers‘) can relatively easily be achieved through the thorough consideration of the fluid flows into and within the vessel and ensuring these flows are handled in a smooth manner. The selection of high performance vessel internals in this regard is critical as the cost benefits of cheap internals do not weigh up to the advantages of achieving much higher separation efficiencies and the risks of poor performance, e.g. compressor failure(s). Inlet device: the most critical item The most critical item is the selection of the inlet device. In the industry a wide range of types is being used, ranging from inlet baffles, half open pipes to more elaborate vane type inlet devices and cyclonic inlet devices. Irrespective of the service, only vane type inlet devices and cyclonic inlet devices will handle the fluids smoothly enough at the inlet nozzle to benefit most during the remaining separation process. This is being recognized by ASCOM and this approach has also been applied to the other internals in the HiPer product range!

Droplet coalescence: maximizing overall performance The bulk of the separation takes place by gravity between the inlet nozzle and the mist eliminating equipment. In situations where conditions are demanding (high liquid loading, high operating pressure, small vessel) coalescers can be considered to maximise separation efficiency. Obviously this technology can also be employed to reduce the vessel size.

Mist elimination: protection of downstream equipment The overall mist eliminating efficiency depends on the amount of liquid entrained in the gas, the droplet size distribution, and the efficiency of the mist eliminating equipment. The equipment will be selected and designed such to ensure the highest performance under the particular operating conditions.

Summary The advantages of the ASCOM HiPer internals are: • Maximise droplet coalescence, • Maximise overall liquid separation efficiency

from gas, • Excellent turndown characteristics, • Low pressure drop, • Clean & fouling service possible, • No maintenance due to robust design, • Removable through Man Way, • No welding required for installation, • Easily replaces existing older internals.

Tangential deoiling hydrocyclones have long been present on the upstream produced water market. With governments around the globe increasingly sharpening the maximum allowable oil in water discharge quantities to a maximum of 20 ppm and below, convention-nal hydrocyclones are often not adequate to meet these new national and international regulations.

MixedFlow Hydrocyclones Contrary to tangential or axial cyclones, the ASCOM MixedFlow Hydrocyclone is based on a mixed flow principle, which results in a stabilizing and coalescing effect on the oil-water flow. All available pressure energy is converted in to a rotating motion within the cyclone. This results in the generation of much higher G-forces that will be responsible for an adequate and stable oil-water separation. Adverse effects usually emerging in conventional cyclones, such as boundary layer disturbances and flow-destabilization do not occur and, not surprisingly, recent test data confirms earlier findings that the ASCOM MixedFlow Hydrocyclone has an excellent performance by showing both very high separation efficiency and a low pressure drop.

Summary The advantages of the ASCOM MixedFlow Hydrocyclone are: • Extremely high separation efficiency, • Very low pressure drop, • Low maintenance due to robust design, • Easily replaces existing hydrocyclone liners.

In the processing industry a wide range of inlet devices are being used ranging from inlet baffles, half open pipes to more elaborate vane type inlet devices and cyclonic inlet devices. Irrespective of the service, only vane type inlet devices and properly designed cyclonic inlet devices will handle the fluids at the inlet nozzle adequately and will maximise the separation performance. All other inlet devices will result in a very poor gas distribution AND in an increase of the liquid content entrained in the gas due to the high shear forces exerted by these devices.

Ensuring excellent bulk gas / liquid separation The overall separation efficiency of a particular vessel can only be maximised when the bulk amount of the liquid is separated at the inlet nozzle. This requires the incoming fluid flow to be smoothly introduced into the vessel such that the velocities are reduced and the liquid can separate by gravity. The ASCOM HiPer Vane Diffuser will ensure an adequate gas distribution as a direct result of its aerodynamically optimised vane geometry. The geometry and layout contain large open areas and therewith ensures that there is no additional pressure drop, no potential for blockage and no maintenance required due to the very robust design.

Summary The advantages of the ASCOM HiPer Vane Diffuser are: • Smooth introduction of fluids in to vessel, • Maximises liquid drop-out, • Good gas distribution, • Integrated Flow Conditioner, • No pressure drop, • No blockage possible due to large open areas, • No maintenance due to robust design, • Removable through Man Way, • No welding required for installation, • Easily replaces existing older inlet devices.

The HiPer Inlet Cyclone Separator can be applied as inlet device in both vertical and horizontal 2 and 3 phase separators. The HiPer Inlet Cyclone is based on the principle of creating centrifugal forces in order to perform efficient gas-liquid separation. The multiphase flow from the inlet piping is gently introduced into the cyclone with a special designed low shear inlet section. Inside the cyclone gas and liquid are separated by g forces, liquid flows downwards into the liquid section of the separator and gas exits through the vortex finder of the inlet cyclone after which further demisting can be performed in downstream equipment if necessary.

Ensuring excellent liquid-liquid separation and foam breaking performance The low shear design and moderate g forces in the HiPer Inlet Cyclone are beneficial in three phase separation and applications where foam is present in the inlet stream due to the foam breaking performance of the cyclone. Strong reductions of anti-foam chemicals are possible with HiPer Inlet Cyclones in foam sensitive applications.

Summary The advantages of the ASCOM HiPer Inlet Cyclone Diffuser are: • High gas and liquid handling capacity, • Efficient bulk gas-liquid separation, • Low shear design to enhance oil-water

separation, • Geometry optimised with R&D and CFD

simulations, • Foam breaking, • No maintenance due to robust design, • Installation through Man Way, • No welding required for installation, • Wide operating range of 0—100% of design

flow, • Easily replaces existing older inlet devices.

HiPer Cyclone Mist Eliminator State-of-the-art cyclonic mist elimination

In situations where the conditions are demanding due to an elevated operating pressure, a large amount of liquid entrained in the gas or limited gas space / vessel diameter available, demisting cyclones have increasingly been accepted over the past decade. To date several generations of mist eliminating cyclones have been put in to operation. ASCOM now introduces: The Newest Generation of cyclonic mist eliminating:

ASCOM HiPer Mist Elimination Cyclone

Particular and significant improvements have been made to the cyclone design using the special advanced aeronautical technology for optimising the vane blade’s aero dynamical shape to achieve an even better pressure to velocity conversion. This leads to reduced pressure drops and lower shear stresses between the gas and liquid within the cyclone. These two parameters allow a higher gas flow rate per cyclone tube and consequentially this can lead to smaller vessel sizes or higher throughputs in retrofit situations. In addition to this, the cyclones liquid handling capacity has been increased significantly. This makes the ASCOM Cyclone Mist Eliminator not just another 3rd Generation Cyclone type, but its capabilities push the cyclone to a whole new level:

The next generation in demisting!!

Summary

The advantages of the ASCOM HiPer Mist Eliminating Cyclones are: • Newest Generation demisting cyclones, • Designed with advanced aeronautical

technology, • Maximises liquid droplet separation from gas, • Significantly increased liquid handling capacity, • Excellent gas distribution properties, • Excellent performance in fouling service, • Reduced pressure drop, • No maintenance due to robust design, • Removable through Man Way, • No welding required for installation, • ASCOM State of the Art technology, • Easily replaces existing older mist eliminating

equipment.

When gas and liquid enter a horizontal vessel the flow velocity is relatively high and only after the flows properly have been distributed over the entire available cross-sectional area, separation can take place to achieve the efficiencies predicted by calculation.

Liquid Distribution Optimised For horizontal vessels equipped with vane type inlet devices the fluids are being introduced much more evenly and consequently at lower velocities. As a result of the pressure drop over the downstream demisting equipment an even gas distribution can be achieved. However, for vessels equipped with cyclonic inlet devices the gas exiting these cyclones in jets needs redistribution to maximise the liquid drop out due to gravity separation. In order to maximise the separation of oil droplet from water and water droplets from oil separation, horizontal three phase separators require distributions baffles in the liquid phase. The liquids dropping down from the vane type inlet device or those being introduced through the inlet cyclones create a highly turbulent inlet liquid zone. The liquid velocities need to be reduced and evenly distributed over the entire cross-sectional area. This is best achieved by introducing liquid distribution baffles.

Summary The advantages of the ASCOM HiPer Perforated Distributor are: • Maximises liquid droplet separation from gas, • Maximises oil separation from water, • Maximises water separation from oil, • Excellent sand handling capability, • Low pressure drop, • No maintenance due to robust design, • Equipped with removable Man Way, • Removable through vessel Man Way, • No welding required for installation, • Easily replaces existing older perforated

baffles.

Produced sand can be removed from one or more well streams at a wellhead platform or remote location, but it is not always practical or economical to do so. Therefore, most operators chose to have the sand settle in the separators first, from where it can be removed from the process system. The first step thereto is to fluidise the sand into a motion fluid and route it to a location for accumulation, cleaning and packaging.

Principle ASCOM has developed a number of complemen-tally solutions to fluidise solids. The HiPer Solids Removing Cyclones introduce a cyclonic flow of produced water into the layer of solids which leads to the fluidisation of the particles. The cyclonic flow also creates a low pressure zone in the eye of the cyclone, exactly where the extraction point is located. This pressure gradient drives the slurry removal. Per Solids Removing Cyclone a water flow rate is required of less than 5 m

3/hr at a minimum

pressure above the vessel’s operating pressure. However, at low operating pressures in order to extract the slurry from the vessel and process it to its designated location, the flow may require boosting.

Effective Removal Zone Subject to the availability of produced water and the area that needs to be covered, one or more Solids Removing Cyclones can be installed in one or multiple sections. A minimum distance is kept between the cyclones for the circulating water flow around each cyclone not to interfere with one another. The effective solids removal zone is approximately 1 meter in diameter and as a consequence, solids outside this zone will only be removed provided the angle between the solids and the effective removal zone is larger than 34 degrees, the repose angle of sand.

Reliability confirmed for Sub-Sea Separation In view of the fact that the Solids Removing Cyclone only contain large openings, the design is very robust and very reliable, to such extend that the technology has been qualified for use in sub-sea separators by a major oil company.

Multi-Purpose Applications In view of the low water requirement and the ability to fluidise considerable amounts of solids within a reasonable period of time, the HiPer Solids Removing Cyclone forms the basis of ASCOM’s solids handling approach. Besides removing solids from a vessel, the cyclone can be employed to transport accumulated solids over a larger distance to a bagging station for instance, or used to cycle the solids between accumulators during solids cleaning operations.

Summary The advantages of the ASCOM HiPer Sand Removing Cyclone: • Low motion fluid flow rate required • Good sand fluidisation & removal • Excellent sand removal in combination with

HiPer Sandjetting System • Not prone to blockage • Excellent performance in fouling service • Excellent pressure drop characteristics • Low maintenance due to robust design • Removable through Man Way • No welding required for installation • Easily replaces existing older sparging

equipment • Can be used in combination with: HiPer Sandjetting System, HiPer Solids Accumulator, HiPer Solids Cleaning System, and HiPer Solids Bagging Station.

The space availability for economic debottlenecking of existing facilities has increasingly reduced and the installation of minimal facility platforms has significantly increased over the past decade. This resulted in the development of compact (―in-line‖) gas-liquid separation equipment, built according to piping specification.

Design improvements ASCOM has developed and patented a set of new innovative solutions to overcome the limitations experienced with the first generation of compact separation equipment. The particular design approach that forms the basis of these solutions leads to a stabilizing and coalescing effect of the fluid flow and adverse effects usually experienced in inline cyclones, such as boundary layer disturbances and flow-destabilization, do not occur. In addition, the TwinLine Gas/Liquid Separator is based on a 2-stage separation principle. This results in the ASCOM TwinLine Gas/Liquid Separator design to stand out in three areas: 1) Higher overall liquid separation efficiency, 2) Higher liquid handling capacity, incl. under

dynamic flow conditions such as slugs, 3) Improved turn-down performance. Higher overall liquid separation efficiency The first stage of the TwinLine Gas/Liquid Separator is designed to separate the bulk of the liquid, similar to a conventional and single boot inline separator. Where the liquid not separated in this stage becomes actual carryover in the conventional design, the second stage of the TwinLine Gas/Liquid Separator reinforces the fluids’ rotational motion due to the particular design characteristics, such that the droplets still entrained can be separated efficiently. The estimated liquid from gas separation efficiency for the conventional design would be in the range of 90 to 98%, subject to the particular operating conditions. The estimated liquid from gas separation efficiency achieved by the TwinLine Gas/Liquid Separator is similar to a conventional design in the first stage and whereas the second stage boosts the overall separation efficiency and operational reliability under dynamic flow conditions.

Higher liquid handling capacity, incl. under dynamic flow conditions such as slugs As a result of an overall higher separation efficiency achieved in two stages, firstly the liquid load to the downstream equipment is significantly less, and/or secondly the TwinLine Gas/Liquid Separator can handle and increased liquid flow compared to the conventional single-stage design with similar performance. This makes the TwinLine Separator much more reliable under more dynamic flow conditions, as the second stage effectively and efficiently watches over the performance of the first stage and covers where necessary. Improved turndown performance As a result of its design, a TwinLine Separator has a better turndown performance than a conventional single boot inline separator design. Under turndown conditions the first separation stage will likely see a reduction in the separation efficiency as the reduced driving force may affect the liquid film stability. This often leads to liquid carryover. Due to the presence of the second stage and due to its particular design characteristics, the fluids’ motion is reinforced such that efficient droplet separation can occur, even under turndown conditions.

The space availability for economic debottlenecking of existing facilities has increasingly reduced and the installation of minimal facility platforms has significantly increased over the past decade. This resulted in the development of compact (―in-line‖) gas-liquid-sand separation equipment, built according to piping specification.

Design improvements ASCOM has developed and patented a set of new innovative solutions to overcome the limitations experienced with the first generation of compact separation equipment. The particular design approach that forms the basis of these solutions leads to a stabilizing effect of the fluid flow and adverse effects usually experienced in inline cyclones, such as boundary layer disturbances and flow-destabilization, do not occur. This results in the ASCOM Inline Desander design to stand out in three areas: 1) High overall sand separation efficiency, 2) High gas handling capacity, 3) Low pressure drop. High overall sand separation efficiency The fluids are brought into rotation by a static swirl element. This swirl element is designed using air-foil technology to ensure a stable flow in the separation chamber. As the direction and the velocity of the fluid flow are identical around the circumference of the desanding cyclone, this leads to a very stable liquid film and boundary layer through which the particles migrate to the wall. In the event gas is present, the liquid film is further stabilized. The absence of disturbances in the liquid film avoids significant particle re-entrainment. In addition to this, in order not to disrupt the driving force that keeps the liquid film stable, the gas and liquid flow are extracted in a very gradual manner from the separation chamber. This leads to a high overall sand separation efficiency in a highly compact manner. The separation efficiency of the ASCOM Inline Desander is significantly higher than that of commonly used sand traps. This makes the Inline

Desander an ideal technology to remove the bulk of the sand before it enters the separator. This can save significant downtime and associated costs to remove the sand from the separators manually. The Inline Desander can be installed during a brown field modification project or integrated in the process during the engineering stage of a new built facility.

In situations where the sand load is very high or sand slugs may be occurring, the Inline Desander can be designed in a 2-stage configuration. In the first stage, the bulk of the sand is separated and in the second stage, as a result of the smaller diameter of the cyclone, a separation polishing effect is achieved due to the higher g-forces generated.

High gas handling capacity As a direct result of the even fluid flow distribution across the circumference of the Inline Desanding cyclone and the gradual extraction of the fluids from the separation chamber, the Inline Desander is able to handle a gas volume fraction of 0 – 100%. When processing fluids with high gas volume fractions, the liquid film is actually stabilised and as a result the sand separation efficiency continues to be high. The Inline Desander is always tailor-made to suit certain pressure drop limitations and efficiency requirements. The designs proposed typically consider the bigger picture and are therefore often unconventional and making use of ASCOM’s complementary compact separation technologies. Yet they are attractive for their compactness, cost & delivery time.

Summary The advantages of ASCOM Inline Desander: • Very compact design – ―In-Line‖, minimising

space and weight requirements • High separation efficiency • Streams with 0 – 100% Gas Volume Fraction

can be handled • One or two separation stages, if required • Low pressure drop • Low maintenance due to robust design • Retrofit: replaces existing sand traps, older

This resulted in the development of compact (―in-line‖) gas-liquid separation equipment, built according to piping specification.

Design improvements ASCOM has developed and patented a set of new innovative solutions to overcome the limitations experienced with the first generation of compact separation equipment. The particular design approach that forms the basis of these solutions leads to a stabilizing and coalescing effect of the fluid flow and adverse effects usually experienced in inline cyclones, such as boundary layer disturbances and flow-destabilization, do not occur. In addition, the TwinLine Degasser, subject to the performance requirements and operating conditions, is based on a single or dual-stage separation principle. This results in the ASCOM TwinLine Degasser design to stand out in two areas: 1) Higher overall gas separation efficiency, 2) Improved turn-down performance. Higher overall gas separation efficiency The first stage of the TwinLine Degasser is designed to separate the bulk of the gas. Where the gas not separated in the first stage becomes actual carryunder in the conventional design, the second stage of the TwinLine Degasser reinforces the fluids’ rotational motion due to the particular design characteristics, such that the gas bubbles still entrained can be separated efficiently. The estimated gas from liquid separation efficiency achieved by the TwinLine Degasser is similar to a conventional design in the first stage and whereas the second stage boosts the overall separation efficiency and operational reliability under dynamic flow conditions. However, where sufficient pressure drop for the gas phase and sufficient liquid carryover handling capacity for the liquid is available, a single stage Degasser could be sufficient to achieve the required performance.

Improved turndown performance As a result of its design, a TwinLine Degasser has a better turndown performance than a conventional single boot inline degasser design. Under turndown conditions the first separation stage will likely see a reduction in the separation efficiency as the reduced driving force may affect the gas core stability. Subject to the pressure drop available on the gas side, this may lead to a reduced gas extraction. Due to the presence of the second stage and due to its particular design characteristics, the fluids’ motion is reinforced such that efficient gas separation can occur, even under turndown conditions.

Summary The advantages of ASCOM TwinLine Degassers: • Very compact design – ―In-Line‖, minimising

space and weight requirements • High separation efficiency • High Gas content in Liquid can be handled • One or multiple separation stages • Low pressure drop • Low maintenance due to robust design • Changes the gas/liquid flow regime favorably • Retrofit: replaces existing pipe spools
