System For Recovering Glycol From Glycol/Brine Streams

US Patent:
6444095, Sep 3, 2002
Filed:
Nov 30, 1999
Appl. No.:
09/451832
Inventors:
Richard I. Evans - Baton Rouge LA
Ralph L. Hicks - New Orleans LA
Rita W. Girau - Harvey LA
Kiel M. Divens - New Orleans LA
Timothy R. Dunning - The Woodlands TX
Assignee:
Reading Bates Development Co. - Houston TX
International Classification:
B01D 126
US Classification:
202174, 159 21, 159 171, 159 46, 159DIG 8, 159DIG 40, 159 44, 202160, 202176, 210294
Abstract:
A system for recovering glycol from glycol and brine mixtures produced from oil or natural gas wells that combines energy efficiency with a capability for handling salt and other solids contained in the mixture. The system comprises three effect evaporator systems in series. Each effect evaporator system comprises an evaporator, a separator vessel, product pumps, and a solids removal system. The process utilizes the system to remove salt and other solids as well as excess water leaving a glycol stream that can be reused as a hydrate inhibitor. The process begins by preheating a glycol/brine stream comprising approximately fifty percent (50%) glycol. The stream is then subjected to three evaporation cycles. The first evaporation cycle comprises introducing the preheated stream into a suppressed boiling point evaporator where the stream is heated under a constant pressure. The stream pressure is then dropped to cause a portion of the water contained in the stream to vaporize or flash.
