Feasibility Study of Integrating Multi Effect Desalination and Gas Turbine Systems for Lavan Island Oil Refinery

In this research, feasibility study of integrating thermal desalination unit with Gas Turbine (GT) has been investigated using retrofit and grass root design techniques for Lavan Island Oil Refinery which is located in Persian Gulf. According to computed parameters on developed code for the power generation unit No.1 using EES (Engineering Equation Solver) software, thermal efficiency of the GT unit No.1 and thermal energy recovered by HRSG (Heat Recovery Steam Generator) are equal to 22.79% and 4847 kW, respectively. Therefore, it shows a considerable potential on heat recovery and motive steam production. Effect of variations on different quantitative and qualitative parameters has been reviewed on the next step of this research. Finally, effect of engineering and economical parameters has been compared based on the following scenarios:● Integrating available Thermal Desalination Unit (TDU) with available steam boiler,● Retrofitting available TDU with HRSG,● Integrating GT unit No.1 with novel simulated TDU based of grass root design.As a result, based on economical model, which has been developed using GAMS (Generalized Algebraic Modelling System) software, the selected scenario is the third scenario.
