Landfill Gas Filtration


The Application

Landfill waste decomposes and produces what is known as landfill gas. This gas is composed mainly of methane and carbon dioxide, with small amounts of other gases, organic (non-methane) and inorganic compounds. Landfill gas has proven to be a reliable energy source for both industrial and residential use, and its conversion reduces greenhouse gas emissions, pollution and energy costs. 


Landfill gas is collected in underground wells, brought to the surface and compressed before being sent out for resale and delivery.


The Problem

Landfills are naturally dirty and retain particulate and moisture. Temperature changes increase the amount of condensate at both the heat exchanger outlet and gas collection point. Inadequate filtration of produced gas will lead to:

  • System compressor damage
  • Heat exchanger fouling
  • Unpleasant odors
  • Safety hazards and other problems at energy usage sites


The Solution

Filtration of collected landfill gas entering into the compressor will eliminate particles, liquid slugs and aerosols that could otherwise damage downstream equipment. A coalescer should be placed downstream of the heat exchanger to collect any compressor lube oil and condensed liquids.
