ABSTRACT:
Antifreeze agents such as methanol used in treating hydrocarbon-containing streams to prevent the formation of hydrates and ice are recovered in a combination process comprising extraction, fractionation, and stripping together with a common reboiler system for the fractionation and stripping. One process comprises a combination of solvent extracting methanol with water, fractionation of the water-methanol extract to separate methanol overhead, further treatment of the fractionation bottoms by stripping to remove residual methanol overhead which is returned to the fractionation zone, and recycling at least a portion of the fractionation bottoms as solvent to the initial extraction step.
