Abstract
Fluid streams, particularly natural gas, are desulphurized by passage over a bed of a particulate absorbent containing zinc oxide at below 120.degree. C. In order to increase the absorption capacity of the absorbent, the water and temperature of the fluid stream is controlled so that the stream both entering and leaving the absorbent bed has a degree of saturation of at least 30%, but does not contain a separate liquid aqueous phase.
