Abstract
An improved method of treating streams having mercaptan or mercaptan-based compounds therein particularly adapted for the processes of sweetening sour hydrocarbons and regenerating spent caustic solutions is described. The invention comprises contacting a first stream having the mercaptan or mercaptan-based compounds therein with a second stream in the presence of effective amounts of a nitrogen-based promoter to promote the extraction and/or the catalytic oxidation of the mercaptan compounds therein. The invention herein disclosed and described is applicable in a wide variety of apparatus and processes adapted for sweetening and regeneration operations.
