Optimization of waste heat utilization in pipeline compressor station
Gas turbine driven pipeline compressor stations employed in existing pipelines and also in those that will be built due to increasing demand for natural gas present significant potential for production of additional electricity and useful heat by utilizing the waste heat from gas turbine process.The paper analyzes and compares several different configurations of heat recovery steam generator (HRSG) both in the terms of thermodynamic and thermoeconomic criteria. In order to find an optimal configuration an exergo-economic HRSG optimization is conducted for finding the compromise between the cost of exergy losses and investment costs of HRSG surfaces. Comparisons and selection of configurations are based on the Pareto front thorugh finding an optimum between maximal system efficiency and minimal cost of elctricity.
