Hydroprocessing - Refining Process
Reaction of vacuum distilled crude oil and
hydrogen at high temperatures
(> 500 C) and pressure
(> 70 bar) in presence of a catalyst
Contaminants are eliminated andnaphthenics and aromatics are converted
to paraffinics.
Conversion of paraffins to iso-paraffins to
improve low temperature characteristics
Hydrofinishing is used to make moleculesize more uniform and remove remaining
sulphur and aromatics

Viscosity
A measure of fluid's resistance to flow.
Describes fluid resistance to shear force.
Determined by molecular chain length
A fluid with high viscosity resists motion
because its molecular makeup gives it alot of internal friction.
A fluid with low viscosity flows easilybecause its molecular makeup results invery little friction when it is in motion
Measured in two ways Dynamic (Constant Pressure Head)
Kinematic (Changing Pressure Head)

Kinematic viscosity
is measured based on the time required fora given amount of fluid to flow througha certified capillary while the pressure headis allowed to drop
Units: Stokes (CGS Unit)
1 cSt = 10-2 cm2/s = 10-6 m2/s = 1 mm2/s
Units: Saybold Universal Seconds (SUS) Time in seconds for 60 milliliters of oil to flow
through a standard orifice at a given temperature.(ASTM Designation D88-56.)
Standard in (European) Oil Industry:Kinematic Viscosity at 40C(most common unit: mm2/s)

Dynamic viscosity (=Absolute
viscosity) is measured based on the time required for
a given amount of fluid to flow through acertified orifice under a constant pressure head
can also be measured by a shear diskviscometer (e.g. Brookfield Rotating Disk Viscometer)
Units: Pas (MKS Unit)1 mPas = 10-3 Pas = 10-3 kg/ms = 1 g/ms = 10-2 P(Poise)
Relationship to Kinematic Viscosity
Dynamic Viscosity = Kinematic Viscosity x Densityor mPas = cSt x g/cm3

Pour Point
The Pour Point- the lowest
temperature an oil or distillate fuel isobserved to flow, when cooled underconditions prescribed by test methodASTM D 97.
The Pour Point is 3C (5F) above thetemperature at which the oil in a testvessel shows no movement when thecontainer is held horizontally for fiveseconds.
In other words, the lowest temperaturea fluid pours from a container
one indication of low temperaturecapability

Reciprocating Compressors
L-4610 Primary Recommendation ISO 100 blend of diester and hydro cracked mineral oil with
R&O + AW Add Pac
Why diester? Valve deposits and recompression
Limitation on temperature, pressure: Not much over 275F, 8,000 h @ 90C for H2 > 4,000 h @ 90C for H1
conventional mineral oils cost less, butuseful lifetime ranges from 500-1500 hr
Synthetic base oils (PAO)
Extremely low water emulsification
Can be used in Vacuum Pump applications
Suitable for rough vacuums (760 torr 1torr) and medium vacuum application
(down to 10-3 torr)

Benefits of Synthetic Gear Oils
Improved efficiency (reduced energy
consumption) due to reduced friction losses
Oil change intervals three to five times longer
than mineral oils operating at the same
temperature Reduced Cost for machine down-times
Reduced Cost for disposal of used oil
Reduced operating temperatures under full load
Increased component life
Cooling systems may not be required
