The catalytic conversion of HCN and COS is a cost effective technology to abate the harmful effects these components have in gas streams. This hydrolysis…
CO2 and water vapor removal from natural gas or associated gas to meet pipeline specifications for onshore or offshore locations. Hydrogen and helium purification and…
Purify ethylene feed stream to polyethylene production processes. Treated ethylene gas contains less than 0.2 ppmv CO2 and H2O and less than 1.0 ppmv oxygenates.…
A process that can: • Selectively remove H2S and COS in integrated gasification combined cycle (IGCC), with high CO2 rejection to product gas (+85%) and…
Acid gas removal using an organic solvent at low temperatures. In general, methanol is used for H2S, COS and bulk CO2 removal, whereby organic and…
Removal of acid gases from natural gas, fuel gas and syngas by physical absorption in NMP (N-methyl-pyrrolidone). Typical cases: 1. High CO2 contents to low…
PURASPEC processes remove low levels of sulfur and mercury compounds from hydrocarbon gases and liquids to meet pipeline, chemical grade or environmental specifications. PURASPEC uses…
Natural gas from reservoirs now being explored is of increasingly poorer quality. By contrast, demands on gas quality are rising. This is particularly true when…
Application: Reject nitrogen from natural gas to increase heating value. Description: Natural gas feed to the nitrogen rejection unit (NRU) is partially condensed and fed…
