THIN-FILM TREATMENT OF HIGH-VALUE GLYCOL AND AMINE SOLVENTS TO REMOVE CONTAMINANTS

摘要

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.
