Industrial Gas Filtration and Generation Division - Bioenergy



Bioenergy is renewable energy stored in organic materials such as plant matter and animal waste, known as biomass. The wide variety of biomass fuel sources include agricultural residue, pulp/ paper mill residue, urban wood waste, forest residue, energy crops, landfills, and animal waste. 


Anaerobic digestion is the process that occurs when bacteria decompose organic materials in the absence of oxygen to generate biogas. Biogas is primarily composed of methane and carbon dioxide with smaller amounts of hydrogen sulphide and ammonia. Trace amounts of other gases like hydrogen, nitrogen or carbon monoxide are also present in the gas. Typically the biogas produced in anaerobic digesters and landfills is saturated with water-vapour and may contain dirt particles. As a result, it is necessary to filter these contaminants prior to any downstream equipment or pipe work. Failure to remove these impurities may lead to a malfunction of equipment and processes downstream and, in the absence of effective dehumidification, can cause clogging or blocking of blowers, heat exchangers, and gas meters — increasing maintenance costs and plant downtime.


Unwanted, damaging substances contained in biogas are:


  • Hydrogen Sulphide
  • Ammonia (NH3)
  • Siloxane
  • Aromatic Hydrocarbons
  • Halogens (Chlorine, Fluorine)
  • Particulate


Biogas, originating from biomass is gaining increasing worldwide importance as a recognized renewable energy source. Biogas production can and will contribute in a significant way to future energy supplies, replacing more and more existing fossil-fuel sources such as coal, oil, or natural gas.

    Anaerobic Digester

    Gas from a digester should be filtered before and after treatment to remove any contaminants or liquids carried over in the process. Filtration after compression is also recommended to remove any compressor oils that may be transported downstream.

    Glycol Dehydration

    Glycol dehydration is an adsorption process in which glycol, a liquid solvent, is used to remove water vapor from natural gas. Glycol dehydration removes water to prevent corrosion and freezing of processing equipment.
