The THIOPAQ O&G process biologically removes hydrogen sulphide from gas streams and recovers it in the form of elemental sulphur in a simple one-step process. Sulphur degassing which includes pressurised degassing, removes hydrogen sulphide and polysulphides from liquid sulphur produced in Claus sulphur recovery units. The process eliminates potential explosion and odour hazards, and the risk to human health. It provides a top-quality sulphur product.
