Claim 17:
18. A method for removing organic acid salts in monoethylene glycol recovery, comprising:
withdrawing a purge stream from a liquid volume of a glycol vaporization separator based on a physical property of the liquid volume indicating buildup of organic salts in the liquid volume wherein the physical property comprises a viscosity or a density;
mixing an aqueous acid with the purge stream to form an acid stream at a rate of the aqueous acid that is based on a pH of the acid stream;
providing the acid stream to a packed distillation column at a location below a packing inside the packed distillation column;
distilling the acid stream to form an overhead stream and a bottoms stream; and
recycling the bottoms stream to the glycol vaporization separator.
