AIRUS biogas system has proven excellent by meeting the boosting requirements in landfill gas management:
1) Landfill Gas (LFG) Management
-Landfill Gas Collection System
-Landfill Gas Flaring
-Landfill Gas Power Generation
- a) Landfill Gas Collection System
A landfill gas collection system is the initial engineering solution required to collect landfill gas into a landfill gas flare or engine. It consisted of several components and considerations such as the:
-Vertical landfill gas wells
-Horizontal landfill gas pipeline system
-Control valves and manifolds
-Condensate dewatering system with condensate traps
-Leachate pumping system
These components shall require various considerations such as, site topography, gradient for piping and other site conditions. Sunsource has the capabilities to design, build, supply and commission effective landfill gas collection and utilization systems that is able to meet stringent CDM requirements.
- b) Landfill Gas Flaring
The simplest way to dispose the LFG collected in an environmental friendly manner is by flaring. LFG flaring involves the destruction of methane gas which is 21 times more hazardous as a global warming agent compared to carbon dioxide. Towards minimizing the global warming impact, Sunsource, based on its many years of experience has developed cost efficient and reliable combustionsystem for LFG flaring able to withstand high temperatures and local conditions.
- c) Landfill Gas Power Generation
Generation of electricity from landfill gas is a step further from flaring whereby the heat energy can be utilized to generate power when tapping methane into gas engines. For the electricity generation to work, the delivery of methane into the gas engines will have to be properly regulated and become constant hence, may require biogas storage tanks. Depending on the gas quality, the landfill gas may be required to be treated via removal of sulphur or moisture to enable proper ignition and the reliability of the gas engines. Electricity generation from methane requires careful engineering and advanced technologies to effectively minimize hazards for the good of the environment.
