Improving Khangiran gas turbine efficiency by two standard and one novel inlet air cooling method

Turbine air inlet cooling is one of many available commercial methods for increasing the performance of a gas turbine. The method that has different configurations could be applied for nearly all gas turbines. This paper offers a comparison between two standard and one exquisite inlet air cooling method, which are used to improve the performance of a gas turbine located at the Khangiran refinery in Iran. These methods have been applied to one of the gas turbines located at the Khangiran refinery. Two common air-cooling methods are based on fogging systems and absorption chillers. The idea behind the novel method is to utilize the potential cooling capacity of the refinery natural gas pressure drop station. The research is part of a plenary program developed to enhance the efficiency of the gas turbine used at the Khangiran gas refinery. Considering the results, it is found that the new method is the most feasible in economic terms, so it has been recommended to be used for improving the performance of the Khangiran refinery gas turbines.
