| titleOfInvention | Use of solvents to reduce caustic scrubber deposits |
| abstract | The present invention is a method of reducing the formation of deposits of deposits occurring in caustic scrubbers used to remove acid gases, comprising the following steps: a) providing a caustic scrubber fed with an aqueous alkali solution comprising essentially one or more NaOH, KOH or LiOH, b) providing an olefin-containing hydrocarbon stream contaminated with oxygenated compound and acid gas, the oxygenated compound may form a polymeric deposit deposit in the presence of an alkaline solution of the scrubber, c) sending said hydrocarbon stream to a caustic scrubber to recover an olefin-containing hydrocarbon stream essentially free of acid gases, At this time, d) introducing an effective amount of solvent that can reduce deposit deposition formation into the caustic scrubber and / or the alkaline solution fed to the scrubber, e) directing the liquid outlet of the scrubber to a means for separating the solvent from the alkaline solution, f) optionally, introducing an additive into the alkaline solution fed to the caustic scrubber and / or the scrubber that can reduce the conversion of the oxygenated compound into a polymeric deposit deposit in the presence of an alkaline solution of the scrubber. In an embodiment the solvent separated from the alkaline solution in step e) is treated to remove the heavy compound and recycled in step d). The treatment can be stripping or distillation. In an embodiment the means of step e) for separating the solvent from the alkaline solution is located at the bottom of the scrubber. In an embodiment the caustic scrubber has several stages with various caustic concentrations. Solvent injection and removal may be located at each stage. |
