COS removal

COS removal is carried out by a two stage process which involves the hydrolysis of the COS and the subsequent absorption of the H2S which is produced by the reaction.  A similar reaction mechanism can also be employed to carry out the hydrolysis of CS2.

Johnson Matthey’s range of PURASPEC absorbents are designed for COS removal from natural gas, LNG and LPG in a range of different applications within Gas Processing, Refineries and Petrochemical markets.
