Abstract
PURPOSE: To efficiently and economically remove the SOX in exhaust gas by activating semicoke to prepare an adsorbent, desulfurizing exhaust gas by the use of this and reducing the sulfuric acid formed on the adsorbent by the hydrogen-contg. gas in the system.
CONSTITUTION: Coal is supplied to a boiler 6 and its exhaust gas is put in contact with semicoke by an adsorber 10, whereby it is desulfurized. The coke, etc. powdered in this process are burned by a boiler 6. Part of coal is carbonized by a carbonizer 24 at 500W800°C, and the semicoke is activated by oxygen-contg. gas and steam in an activator 30 and is then sent into the adsorber 10. The hydrogen- contg. gas generated in the carbonizer 24 and activator 30 is sent to a desorber 14 where the semicoke with deposited sulfuric acid sent from the adsorber 10 is reduced and sulfuric acid is desorbed in the form of H2S. The H2S-contg. gas is sent through a conduit pipe 38 to a Claus reaction furnace or the like. The semicoke regenerated in the desorber 14 is joined with the semicoke sent from the activator 10 and is returned into the adsorber 10.
