PROCESS FOR PRODUCING A SWEETENED HYDROCARBON STREAM

摘要

A process of producing a sweetened liquid hydrocarbon stream. In order to prevent the forming of acid species in a sweetening zone, a oxygenate removal zone is disposed upstream of the sweetening zone. The oxygenate removal zone may comprise a water wash or an adsorbent zone, including a regenerable adsorbent. The sweetened stream is formed from a least a portion of liquid natural gas stream which may be scrubbed free of hydrogen sulfide and dehydrated before passing to the oxygenate removal zone.

1. A process for producing a sweetened hydrocarbon stream, the process comprising:
passing a liquid hydrocarbon stream to an oxygenate removal zone; removing oxygenates from the liquid hydrocarbon stream in the oxygenate removal zone to form an oxygenate lean stream; passing the oxygenate lean stream to a sweetening zone to convert mercaptans in the oxygenate lean stream in disulfide and produce a sweetened hydrocarbon stream.
