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.

A process for treating a liquid hydrocarbon stream, comprising:
- passing the liquid hydrocarbon stream previously contacted with a solvent comprising an alkanolamine consisting of diethanolamine, a methyl diethanolamine, or a mixture thereof, and an alkali to a vessel wherein the vessel contains a coalescing zone for removing at least one of hydrogen sulfide and carbonyl sulfide.
A process for treating a liquid hydrocarbon stream, comprising:
- A) passing the liquid hydrocarbon stream previously contacted with a solvent comprising a diethanolamine, an alkali, and water to a contacting zone;
- and
- B) passing the contacted stream to a coalescing zone comprising a hydrophilic mesh for removing at least one of hydrogen sulfide and carbonyl sulfide.
A process for treating a liquid hydrocarbon stream comprising:
- A) passing the liquid hydrocarbon stream previously contacted with a solvent comprising an alkanolamine consisting of a diethanolamine, a methyl diethanolamine, or a mixture thereof, and an alkali through a contacting zone;
- B) passing the contacted stream to a vessel containing a coalescing zone for removing at least one of hydrogen sulfide and carbonyl sulfide;
- and
- C) passing a stream from the vessel to an extraction zone.
