The ADIP® process removes hydrogen sulphide and carbon dioxide from natural gas, refinery gases and off-gas from the SCOT® Shell Claus off-gas treating process, as well as hydrogen sulphide and carbonyl sulphide from natural gas liquids (NGL) and liquefied petroleum gas (LPG).
The Sulfinol® process removes hydrogen sulphide, carbon dioxide, carbonyl sulphide, mercaptans and organic sulphur components from natural gas and synthesis gas from coal and oil gasifiers, and steam reformers.
The SCOT Shell Claus off-gas treating process enhances sulphur recovery from Claus plant to over 99.9%, and can help to meet the most stringent environmental limits.
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.
The SulFerox process converts hydrogen sulphide directly to elemental sulphur and has particular cost-advantages in treating gases containing small quantities of hydrogen sulphide.
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.
The HCN/COS hydrolysis process catalytically converts hydrogen cyanide and carbonyl sulphide, and has its main application in synthesis gas treatment.
The CANSOLV® SO2 Scrubbing System process enhances sulphur recovery by removing sulphur dioxide post-combustion and recycling it back to the Claus plant. The process offers over 99.9% overall sulphur recovery and can help to meet the most stringent environmental limits.
The CANSOLV Integrated SO2-CO2 process offer joint post-combustion removal of sulphur dioxide and carbon dioxide, and their recovery as pure streams.
The SORDECO® process uses fixed-bed adsorption technology to improve the water and hydrocarbon dew-point specification of natural gas.
The molecular sieve design and service package helps gas and liquefied natural gas (LNG) plants to improve the operating cost, bed life, reliability and availability for molecular-sieve dehydration and mercapton-removal units. A combination of a molecular sieve and the Sulfinol process integrates dehydration and acid gas removal to focus on deep (organic) sulphur removal.
