DEVELOPMENT OF SMOVEN PROCESS FOR HOT GAS DESULFURIZATION

The Beijing Research lnstitute of Coal Chemistry (BRICC) is developing the SMOVEN process for hot gas desulfurization. The SMOVEN process features sulfidation in an entrained bed,regeneration in a low velocity fluid bed or a moving bed with oxygen and sorbent circuIation con-trolled by gas stream. A series of tests on the bench scale unit and the continuous process devel-opment unit were carried out. The regenerable metal oxide sorbents were adopted for the sulfur-related components removing from coal gas at the temperature of 550-650℃. A fluidized bed gasifier of 100 mm (id) generated coal gas for tests. The principle of SMOVEN process has been positively verified.
