APPARATUS AND CATALYTIC PARTIAL OXIDATION PROCESS FOR RECOVERING SULFUR FROM AN H2S-CONTAINING GAS STREAM

Title:

APPARATUS AND CATALYTIC PARTIAL OXIDATION PROCESS FOR RECOVERING SULFUR FROM AN H2S-CONTAINING GAS STREAM

Document Type and Number:

WIPO Patent Application WO2006091658

Kind Code:

A3

Abstract:

The disclosed sulfur recovery system and process avoid some of the operational problems of conventional Claus plants and processes by replacing the reaction burner and furnace tube of a conventional Claus plant with a more efficient short contact time catalytic reactor assembly containing a SPOC catalyst that operates efficiently at elevated temperatures. Such Claus plant modification also reduces or avoids the negative effects of hydrocarbons, CO2 and ammonia in Claus sulfur plant feeds, and permits efficient processing of dilute to concentrated H2S feeds. The disclosed modification makes possible the expansion of Claus plant capacity at lower cost.
