Teofipol Energy Company. Biogas in Ukraine

The heat generation unit has been commissioned. The system utilises heat from the exhaust gases of the gas turbine unit.
Thermol 32 thermal oil is used as the heat transfer fluid. Heat is transferred via the circulation of thermal oil in a closed circuit from the four flue gas heat recovery units of the cogeneration plants
to the six economisers, which are the end users of the heat.

Components of the production line:

• shell-and-tube heat recovery units
• exhaust gases from the gasification unit – thermal oil – 4.
• biogas boiler for heating thermal oil – 1.
• expansion tank – 1.
• system drain/fill tanks – 2.
• circulation pump – 1.
• distribution pumps – 6.
• system drain/fill pumps – 2.
• flue gas extractor – 1.

The temperature of the flue gases from the gas turbine units is 415°C. The flue gas flow rate from each of the four gas turbine units is 7,460 kg/h. A biogas boiler is used to heat the thermal oil during start-up and as a backup.
At the outlet to the eco-mizers, the heat transfer fluid has a temperature of 240°C. The total heat generation capacity is 1.6 MW.
