Decrease of the cost of drying compressed air by heat recovery at the compressor station

Abstract

Compressed air is widely used as an energy carrier. The compressed air production systems are a part of the auxiliary systems of offsite facilities. It is worth noting that the production of com-pressed air is quite an energy-intensive process, so the potential for energy saving is quite large. There is increasing the efficiency of the compressed air production by developing technology solutions for air preparation in this work. The system of air drying by cooling and the source of cold are considered in this paper. The paper presents a comparison of cooling systems from steam compression and absorption refrigerating machines from the point of view of heat exchange, energy consumption for their own needs, providing cold with required parameters. The economic effect of the proposed circuit solution is given.
