Title:
PROCESS FOR REMOVING SULFUR COMPOUNDS FROM GAS AND LIQUID HYDROCARBON STREAMS
Document Type and Number:
WIPO Patent Application WO2001066671
Kind Code:
A3
Abstract:
The present invention provides a process for removing sulfur compounds including sulfur in the (-2) oxidation state from liquid or gas feed streams, particularly hydrocarbon feed streams. According to the process, such a feed stream including these sulfur impurities is contacted with an absorbent which includes a metal ion-containing organic composition to thereby form sulfur-metal cation coordination complexes in which the oxidation state of the sulfur and the metal cation remains essentially unchanged. The complexes are separated from the feed stream, and the absorbent is regenerated by disassociating the sulfur compound from the complexes.
