Extended lifetime of engines and reduced maintenance by fine - desulfurisation
Biogas Fine Desulphurization
▪ Doted activated carbon allows to absorb large
quantities of hydrogen sulfide
▪ Even in fluctuating conditions, the sulfur can be
deduced constantly below 1ppm
▪ Operation time of the lubrication oil in Biogas
Engines can be doubled
▪ Reduced downtime and maintenance costs for
the engines
▪ cartridge absorbers make
replacement of the active coal very easy.
Removable cartridges can be filled externally
▪ Silicagel indicators dindicate the contidion of
the filling and avoid unnecessary change.

Environmental friendly and cost effective Energy from organic and low calorific production residue.
Integrated Biogas treatment
Integrated Biogas treatment offers
various advantages in terms of
energy efficiency.
▪ Using of existing cooling water instead of installing an expensive chiller
▪ Providing individual Biogas quality in relation with the Consumer (Engines have other requirements then Burners)
▪ Combinations of fuel, for example for process heating plants, allow flexible operation in relation to fuel availability and cost. Multifuel burners and synchronous operation with different fuels are reducing operation cost.

Combination of Biogas utilization with heat recovery to replace fossile fuels
Biogas utilization and heat recovery
• Exhaust Gas from generator will heat up the oil inside the EGHE
• The consumer of this process will be the Air Pre-Heater
• Instead of ambient air, the Main Air Heater will get a pre-heated air from Air pre-heater.
• There for the heat demand from the main air heater will be reduced and the coal consumption also reduced

Utilize Biogas in the best possible way requires an integrated view of all related systems
OVERVIEW PROJECT SIMPLIFIED SCHEME
Requirement: Complete substitution of coal combustion
through the use of excess biogas and waste heat from the
gas engines.
Solution:
• Significantly reduced power consumption by highly
efficient process heating plant.
• Installation of a biogas -fired thermal oil heater to
replace the existing high-temperature heaters.
• Installation of an additional low-temperature air
preheater with associated low-temperature
thermal oil circuit. The engine waste heat can be
optimally utilized in this manner to pre-heat the
process air
Result: The amortization is taken place by the saved fuel
costs in less than 12 months

Multi fuel burners offer better flexibility and therefor reduce energy cost
Liquid, gaseous or dusty production residues can be valuable energy sources.
• Process heaters with multi fuel burnersfor high and medium calorific productionresidues in liquid or gaseous condition.
• Fuel treatments systems to adjustviscosity and to remove particles and other contaminations.
• Fuel control systems to ensureemmission free combustion and safe operation.
• Seamless integration into existing plants and processes
• Remote control systems for centralized plant monitoring, information processing and processcontrol.

BENEFITS
• Highest efficiency
• One System for the complete
residues
• Electricity generation for their
own consumption and for
feeding into the public grid as
well as process heat supplied
to the production
SIMPLIFIED SCHEME OF A COMBINED POWER GENERATION PROCESS
WITH STEAM AND BIOGAS CYCLE
• No use of chemicals
• Easy for water treatment (No
explosion risk due to bad water
quality
• Low temperatures and pressure
for electricity generation
• No super heater is required
• Better part load efficiency
ORC BENEFITS
Complete utilization of all available energy potentials with highest flexibility.
