Natural gas or biogas from digestion processes and landfill sites are used to drive (static cogeneration) engines for power production. When the exhausts of these engines are connected to the Triogen ORC, the total electrical production of the plant will be increased by up to 10%.
The engine condenser load as well as the ORC cooling circuit can be used for preheating the digestion or other processes.

When the engine drives an electrical generator, the electricity production of the system can be increased by 10% or more by using a Triogen ORC as a supplement to the engine. The ORC converts the waste heat of the flue gasses into electricity, so the extra electricity is produced without any extra input by way of extra gas.


Furthermore, a combined application is possible using heat from exhausts and heat from flare, at landfill situations for example.
