PURASPEC absorbents for COS removal
The removal of COS 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 this reaction. A similar reaction mechanism can also be employed to carry out the hydrolysis of CS2.
The choice of absorbent depends on the temperature, pressure and concentrations of other impurities within the hydrocarbon stream.
Please note that this is not the complete range of PURASPEC absorbents for COS hydrolysis. Johnson Matthey representatives should be consulted to determine which product is most appropriate for any given application/duty.
