Abstract:
A method for cleaning a contaminated 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.

Claim (Index 1):
A steady-state method of treating a contaminated solvent stream, the process comprising:\n a. providing a feed stream of contaminated solvent comprising an amine, a glycol, or mixture thereof, and one or more contaminants comprising salts, organics, solids, or mixtures thereof; b. forming and mechanically maintaining a thin film of contaminated solvent disposed on a substrate surface at sub-atmospheric pressure, said thin film having a thickness, wherein the thin film is repeatedly wiped to provide additional contaminated solvent to maintain a film thickness and to move the film along the substrate surface; c. recovering a tops vapor phase comprising the solvent, wherein the concentration of contaminants in the recovered solvent is substantially reduced from the concentration of contaminants in the feed stream, and d. recovering a bottoms phase from the substrate surface, wherein the bottoms phase recovered from the substrate surface comprises contaminants and is a flowable solid material or a tar-like material, said contaminant material comprising less than 20% by weight solvent.
