Thiopaq - A natural process for the separation of hydrosulfuric acid from natural gas

Thiopaq allows removal of H2S from biogas and conventional gas production, and conversion of the H2S into usable sulfur based products including fertiliser.

Thiopaq uses non-hazardous and naturally occurring bacteria to convert H2S (Hydrogen Sulfide) into a sweet gas stream and solid elemental Sulfur. Both are highly marketable products, the latter of which might otherwise be wasted, or burned to produce Sulfur Dioxide in the absence of an efficient separation mechanism. The system also has lower operating costs and material inputs than alternative techniques for H2S separation.

Key features

  • Compared to flaring waste gas, the annual reduction per THIOPAQ unit of one long ton per day (LTPD) sulfur processing capacity is approximately 50,000 tons of CO2, and 1,200 tons of SO2


  • A 40% improvement in operating cost when compared to alternative techniques
