Abstract
One exemplary embodiment can be a process for treating a liquid hydrocarbon stream. The process can include passing the liquid hydrocarbon stream previously contacted with a solvent having an alkanolamine consisting of diethanolamine, a methyl diethanolamine, or a mixture thereof, and an alkali to a vessel. Generally, the vessel contains a coalescing zone for removing at least one of hydrogen sulfide and carbonyl sulfide.
Claims20
A process for treating a liquid hydrocarbon stream, comprising:
- A) combining the liquid hydrocarbon stream with a solvent comprising an alkanolamine consisting of diethanolamine, a methyl diethanolamine, or a mixture thereof, and an alkali to provide a combined stream;
- B) contacting the combined stream in a contacting zone to provide a contacted stream;
- and
- C) passing the contacted stream to a vessel wherein the vessel contains a coalescing zone for removing at least one of hydrogen sulfide and carbonyl sulfide.
