Sour natural gas requires desulphurization or `sweetening`. At least, in most cases. Traditionally natural gas treatment for sulphur removal is done with Claus/amine based scavenging or technology (dry or wet). In the past decades this hasn`t changed much, event though the needs of the market have shifted. Today smaller (shale) multi-well gas fields in isolated locations, gas sources with relatively low H2S content are quite common.

Thiopaq Installations are safe an stable and do not require continuous manning. For a quick overview of the process steps and a deeper understanding of the THIOPAQ O&G technology we have placed an animated movie of the THIOPAQ O&G process on our website. Several companies have developed agricultural fertilizers and fungicides based on the biosulphur produced with the THIOPAQ O&G units. A market for biosulphur now exists. As an alternative the biosulphur can be melted. This addresses the questions around sulphur outlet. Download THIOPAQ O&G Desulphurisation factsheet

Sour gas requires desulphurization. At least, in most cases. Traditionally this is done with amine/Claus based technology (wet or dry) , caustic scrubbing or scavenging. Today, however, smaller refinery gas sources with relatively low H2S content and debottlenecking for refineries are quite common. Off gases from e.g. hydrocracking operations or sour water strippers (SWS) are often difficult to treat economically with more traditional technology
