Landfill gas capture and energy generation
Client: EPSA for Cleanaway
The Boral Western Landfill at Ravenshall / Deer Park plays a critical role in the waste management and resource recovery processes supporting metropolitan Melbourne.
Two new landfill gas conditioning and delivery skids were engineered and manufactured by Energy360. The new design also required re-engineering pipeline
placements for standard equipment.
Using a PD (Positive Displacement) Blower, the landfill gas is extracted from the landfill gas wells at high pressure.
The landfill gas enters the heat exchanger where the gas is cooled to reduce moisture content. The gas flows through a large knock out pot to drop any remaining water.
The PD blower regulates the gas flow, pressurizes the gas and delivers it at a constant temperature, moisture content and pressure to the Caterpillar generators.
What did Energy360 do?
Designed and manufactured two new gas conditioning and delivery skids which could each handle 1,000m3 /hr of landfill gas. Each gas delivery and conditioning skid supplies two only, 1 MW Caterpillar engines. The extracted gas has a high water content and its methane composition varies. The engineered solution accounted for these variables.
The new gas conditioning skids have been operating with maximum uptime since September 2017. Equipment is fit for purpose and the emissions outputs are accurately measured. Electricity is being reliably generated from landfill output, using landfill gas delivered via Energy360’s equipment, contributing significantly to the circular economy
