Abstract: TAIL GAS FROM A CLAUS UNIT IS CONTACTED WITH A BED OF FLUIDIZED SULPHUR REACTIVE MATERIAL SUCH AS LIME UNDER OXI DIZING CONDITIONS IN AN ABSORBER MIN ORDER TO REMOVE SULFUR COMPOUNDS THEREIN. ESSENTIALLY SULPHUR-FREE GAS IS DISCHARGED FROM THE ABSORBER. ABSORBER BED MATERIAL CONTAINING SULFATE (E.G., CASO4) IS TRANSFERRED TO A REGENERATOR WHERE THE CORRESPONDING OXIDE (E.G., CAO) IS REGENERATED UNDER REDUCING CONDITIONS.

Abstract: A SUBSTRATE IS COKED BY CONTACT WITH OIL AT CRACKING TEMPERATURE, AND THE COKED SUBSTRATE IS THEN CONTACTED WITH SULPHUR OXIDES-CONTAINING GASES TO REDUCE THE SULPHUR OXIDES TO SULPHUR (WHICH IS RECOVERED) AND TO OXIDIZE COKE TO CARBON OXIDES. THE CRACKED OIL VAPORS ARE ALSO RECOVERED. THE PROCESS IS OPERATED EITHER CYCLICALLY. INTERMITTTENLY OR CONTINOUSLY.

Abstract: Fuels containing sulphur are purified by (a) partial combustion or (b) full combustion, at 800*-950*C in a bed of CaO and/or MgO which combines with the sulphur. The sulphurized CaO or MgO is reactivated by contact with a regenerator gas at 1,000*-1,150*C with the evolution of SO2. Vanadium and sodium removal from the fuel is enhanced by the presence of iron and alumina, respectively.
