Title:
PROCESS FOR RECOVERING PROCESSING LIQUIDS
Document Type and Number:
WIPO Patent Application WO2000076624
Kind Code:
A3
Abstract:
A process for recovering processing liquids such as gas-treating liquids wherein a feed mixture containing the processing liquid (10), water, and optionally additional components that are more volatile than the processing liquid and components that are less volatile than the processing liquid, is initially heated in a first heating zone (22) to a temperature sufficient to volatilize at least some of the water and a portion of the processing liquid without decomposing the processing liquid to produce a vapor stream (26) containing volatilised water and processing liquid and a residuum (58) containing the bulk of the processing liquid and less volatile component, the vapour stream (26) being separated from the residuum and treated to produce recycle streams of water (18), purified processing liquid, and low and high boiling liquid fractions recovered from the purified processing liquid.
