(US5769909-A)      Hydrocarbon fuel gas hydro-desulphuriser has: an inlet manifold (22) for a mixture of the fuel gas and H2; a bed (44) containing a catalyst for converting the S content to H2S and an absorbent for removing the H2S; a heat exchanger (64) adjacent the bed to pre-heat the fuel gas/H2 stream; a gas conduit (32) for passing a high temperature reformed process gas stream through the heat exchanger to cool the gas stream; and a shift converter (6) adjacent the heat exchanger receiving the cooled gas stream and removing CO exothermically to produce heat taken up in the heat exchanger.    A method for hydro-desulphurisation using the assembly is also claimed.    ADVANTAGE -   The assembly uses the gas stream at various process stages to control the temperature of the hydro-desulphuriser and shift converter beds. A high temperature process gas stream transfers heat to the incoming raw fuel gas stream and also to the steam which flows through the assembly.
