Remplacement des installations de dessalement par procédé multi-étape flash par des refroidisseurs d'eau à absorption : nouveau système de conditionnement d'air urbain dans les pays du Golfe.

Substitution of MSF desalting plants with absorption water chillers: new district air conditioning in Arabian Gulf countries.

Auteurs : DARWISH M. A.

Résumé

In Arabian Gulf countries, steam cogeneration power desalting plants (CPDP) are used extensively to produce both electric power and process heat. The process heat is in the form of steam extracted from steam turbines at pressures of 1-3 bar to desalting units of the multi-stage flash (MSF) type. With the emergence of reverse osmosis system to produce water more efficiently, big amounts of heat remain unused and the general power efficiency of CPDP is reduced. Another application for that unused heat is found in driving chilled water absorption machines for district cooling. The paper illustrates the benefits.
