In this model, refinery waste gases are utilized as a main source of fuel in order to power on gas turbine cycle. The hot exhuasts from L.P.T would power thermal desalination processes (MSF-BR). The plant consists of the following:1-Waste gases source, 2-GTC, 3-Brine heater, 4-MSF.In this sub-Model:1.User should specify the ambient temperature in degree Celsius.2.Also plant productivity should be specified (Md, m3/day). **MatLab-SimuLink should be used to run the model.email us for the password (msherafeldin@gmail.com)Copyright © 2007 by Mohamed A.
