Abstract:
This study examines the performance of a gas compressor station combined with an organic Rankine cycle (ORC) to optimize energy efficiency. Two gas stations with different drivers associated with reciprocating compressor and axial type turbine are considered. The waste heat can be recovered and used from the compressor’s exhaust gas and from the compressed gas that have to be cooled in order to push a higher volume of gas through the pipeline. A thermodynamic analysis on the exhaust gas is performed to determine likely adequate recoverable heat exist used in a Rankine power cycle. Individual models are developed for each component through applications of the first and second laws of thermodynamics. The effects of working fluid types and operating parameters such as compressor pressure ratio, evaporator temperature and temperature difference in the evaporator, on the first and second-law efficiencies for the cycle exergy destruction rate is studied. Finally the cycle thermodynamically is optimized to achieve the best efficiency.
