Modeling and Investigation of Gas Turbines Heat Recovery in the Semnan Oil Pumping Station for Heating Gas-Oil to Reduce Energy Consumption of Pumping
This paper proposed the effect of using a heat recovery system in the gas turbines of Semnan to shahroud oil pumping station in energy conservation point of view. Heating the transferred fluids is one of the common approaches to reduce fluids viscosity and energy consumption, respectively. Due to the low efficiency of station turbines compared to modern turbines, it is expected that the use of heat recovery has a positive effect on improving station performance. By analyzing the combustion products of the gas turbine at the station, the heat extracted from the exhaust gas flow has been calculated which is consumed in the recovery boiler. The pipeline application process including recovery boiler and main equipment of Semnan and Shahroud pumping stations have been modeled. By applying the model, it found that the amount of energy savings by gas-oil heating using a heat exchanger equals to 395311 m3 natural gas in annually. Therefore, optimal points of using combustion heat in the gas turbine output were obtained. In addition, the reduction of power consumption in the presented station has been calculated. Economic calculations were carried out for different countries including Iran, Scandinavian countries, China and the Europian Union average, based on their energy prices and bank interest rates.
