Gas engine reciprocating compressor set is the main process equipment for the pressurization system in gas exploitation, gathering and transportation. Its energy- consumption is huge and the operation efficiency is low. Based on the practice of gas field exploitation, four major energy-saving technologies for the compressor set have been put forward such as enhancing the cooling effectiveness and cutting down the flow loss to reduce the compressor power loss, adjusting the load of the compressor set and optimizing the operating conditions to enhance the adaptability of the set, improving the ignition advance angle and reducing the thermal loss of the engine to increase the engine efficiency, optimizing the muffler and lubricating system to reduce the auxiliary system loss. These technologies can significantly improve the efficiency of the compressor set and reduce the costs of the gas field development and the effect of energy-saving & emission-reducing can be achieved by using this technology.
