DEVELOPMENT OF AN OPTIMIZATION MODEL FOR ENERGY SYSTEMS IN GAS PROCESSING INDUSTRY

Abstract

Energy is required to drive equipment in the Gas processing industry. Energy costs incurred by various energy systems, present in each Gas processing plant, constitute major part of the plant operating expenditures. Optimization of energy systems can help reduce the operating costs of the gas plants and play a part in ensuring the sustainable development of the society. Project is aimed at development of an optimization model (based on case study of Sawan gas plant) which can be used as a guideline for optimization of the gas processing plants in general. Energy systems at Sawan gas plant have been studied as case study. Sawan gas plant is selected as it contains most of the energy systems present in other gas processing plants. For all the systems, different techniques for optimization, based on existing system operational data, design/technology change and SOP changes have been proposed. Technological aspects for proposed changes have been considered with reference to impact on the performance of the existing system. Financial analysis has also been carried out to find out the impact of the proposed changes. Based on both the technological and financial performance, various optimization techniques have been compared. Based on the approach followed for optimization of Sawan gas plant energy systems, an optimization model has been developed which outlines a step by step approach towards optimizing the energy systems in gas processing industry.
