Title:
METHOD FOR DECOMPOSING AND REMOVING ORGANIC SULFUR COMPOUND IN GAS
Document Type and Number:
Japanese Patent JPH0214713
Kind Code:
A
Abstract:
PURPOSE: To efficiently remove org. sulfur compds. in gas by bringing the gas into contact with a catalyst supporting diglycolamine to decompose the org. sulfur compds. and by absorbing and removing H2S produced by the decomposition.
CONSTITUTION: Gas 1 contg. org. sulfur compds. such as COS and CS2 is heated with a gas heater 2 and sent to a tower 3 packed with a catalyst prepd. by supporting diglycolamine on a carrier such as alumina or zeolite to decompose the COS and CS2. H2S produced by the decomposition is sent to a tower 4 packed with an absorbent such as iron oxide or iron hydroxide. Since the H2S is absorbed and removed, purified gas 5 is obtd.
