Johnson Matthey has more than 25 years' experience in purification solutions for the gas processing industry.
We offer PURASPECTM processes, which are based on fixed beds of absorbents to remove traces of contaminants from hydrocarbon gases and liquids. In particular the processes carry out:
- Hydrogen sulphide (H2S) removal
- Carbonyl sulphide (COS) removal
- Mercury (Hg) removal
- Arsine (AsH3) removal.
The choice of absorbent and the design of the reactor vessel will vary according to the type of feedstock, the level of contaminants, pressure and temperature conditions and the pipeline or end-user purity specification.
The processes deliver a wide range of operating benefits:
- Low capital cost
- Impurity removal to very low levels
- Effective low temperature operation
- Easy retrofitting
- No feedstock losses
- High operating flexibility
- Environmentally friendly reprocessing.
PURASPEC performance is well proven within the industry with hundreds of installations worldwide both offshore and onshore. The PURASPEC range of absorbents and technologies is used by most of the major and state owned oil companies.
