H2S is typically present in biogas. Waste streams that are high in proteins containing sulfur-based amino acids like methionine and cysteine, and construction waste can influence biogas H2S levels.

Our activated carbon effectively removes H2S and:

  . Mitigates risk of poisons and foul odors
  . Protects plant equipment from corrosion
  . Ensures compliance with air permits, and
  . Makes RNG profitable by meeting pipeline specifications or enabling use as vehicle fuel
 

Purifying biogas and concentrating the methane also requires the separation of carbon dioxide, water, nitrogen and the removal of other contaminants (siloxanes and VOCs) before it can be called RNG and used interchangeably with pipeline natural gas.

Our DARCO® BG 1, DARCO BG 1P, and ADVANZ® ROZ 3 are high performance activated carbons developed specifically for removing H2S from biogas streams.
