Abstract
A process for removing gases from a sweetened hydrocarbon stream. The process can include passing the sweetened hydrocarbon stream to a gas removal zone, contacting the sweetened hydrocarbon stream with an aqueous stream, passing the aqueous stream to the degassing drum, and removing gases including at least one of oxygen and nitrogen from the aqueous stream. Often, the gas removal zone includes a degassing drum.
Claims16
A process for removing gases from a sweetened hydrocarbon stream, comprising:
- passing the sweetened hydrocarbon stream to a gas removal zone wherein the gas removal zone comprises a vessel and a degassing drum;
- wherein the sweetened hydrocarbon stream is contacted with an aqueous stream in or before entering the vessel;
- wherein the sweetened hydrocarbon and the aqueous streams are separately removed from the vessel;
- wherein the aqueous stream is passed to the degassing drum;
- and
- wherein gases comprising at least one of oxygen and nitrogen are removed from the aqueous stream in the degassing drum.

A process for removing gases from a sweetened hydrocarbon stream, comprising:
- A) passing a hydrocarbon stream to a prewash vessel for contacting with an alkali stream to form a mixture;
- B) passing the mixture from the prewash vessel;
- C) adding air to the mixture to form a combined stream;
- D) passing the combined stream to a reaction zone to convert one or more thiol compounds in the hydrocarbon stream to one or more disulfide compounds;
- E) passing an effluent from the reaction zone to a gas removal zone comprising a vessel and a degassing drum;
- wherein both the effluent and an aqueous stream are passed to the vessel and gases in the effluent are transferred to the aqueous stream;
- and
- wherein the aqueous stream is removed from the vessel and passed to the degassing drum for removing oxygen and nitrogen.
