[Digestion] Rép. : Re: Compressing Biogas into a Tank

[Terrence Sauvé]

Hi Gerry.
Dr. Les Gornall ( Practically Green) uses a compressor to mix his digester and compress the biogas to some extent ( a few bars if I recall ) for the generator pressure regulators. Ask him what are his condensation-hydrogen sulfide removal system and what type of compressor he uses. He is big time with Ajax sour gas engines. He might now what type of equipment the oil and gas industry uses to compress sour gas before refining.

Good luck,

Can biogas be compressed, using a regular air compressor, into a tank? As biogas is 60% methane (CH4), would it have adverse reactions with oil in an air compressor the way acetylene (C2H2) would?
   
  I have seen biogas stored in bladders, huge rubberized bags and telescoping / floating metal tanks. I also remember some discussion in this forum that biogas can be compressed and even be liquefied. These options, however, are too bulky, non-transportable, complex and expensive.
   
  If biogas can be compressed using regular air compressors into a stainless steel compressed air tank (if necessary) to minimize / avoid corrosion -- it would be easier to use say for cooking, lighting, heating, etc. The tank can be re-filled when needed and brought to where the gas will be used. We can have a simple and practical way to make better use of this fuel.
   
  Kindly share any information and/or experience you have. Thank you in advance.
