Abstract: A method cleaning a contaminate solvent used to treat a gas stream, for example a contaminated glycol or a contaminated amine stream, by vacuum evaporation using a mechanically-maintained horizontally-orientated thin film evaporator, where the contaminant material is recovered from the thin film in solvent- free form, as either a heavy organic material or as free flowing salts.

Abstract: A process for removing thiocyanate and other anions from Type II strong base anion exchange resins with an alkali metal hydroxide is disclosed. The process is particularly beneficial to the regeneration and/or reclamation of alkanolamine solutions laden with heat stable salts, especially thiocyanate.

Abstract: There is provided a process for treating a process gas or liquid to remove acid gases which includes treating a relatively lean amine gas scrubbing solution to further reduce the acid gas content of at least a portion of that lean amine gas scrubbing solution such that it becomes an ultra-lean amine solution (one substantially free of acid gas) and the beneficial use of the ultra-lean amine solution to obtain further reductions in the acid gas contents of specific gas or liquid process streams not possible with lean amine solutions having higher residual acid gas loadings. In another aspect of this invention, there is provided a process for producing the ultra-lean amine.
