RETRACTED: Analysis of the efficiency of absorption refrigeration machines for improving the performance of gas turbine gas pumping units

RETRACTED ARTICLE

The article describes the procedure of the system assessment of air temperature of gas turbine compressors operating at linear stations of natural gas compression of gas pipelines in the southern regions of the Russian Federation.
Analysis of statistical data shows that the operation of a number of centrifugal superchargers in the summer does not meet the regulatory and technical requirements of the gas industry, leading to abnormal operation of power machines and equipment. Therefore, the authors propose to cool the air before it is supplied to the gas turbine engines in a special system of absorption refrigeration machines. This additionally expands the functionality of gas turbine units, providing deep air purification, reducing natural gas pressure loss, preventing the entry of various precipitation into the engine, and significantly reducing noise levels.
The article proposes and describes the operation of an original functional scheme that ensures efficient atmospheric air intake for the normal operation of gas turbine gas-pumping units during the summer season in the southern regions of the country. Moreover, the authors present new results of experimental studies of air cooling parameters in absorption refrigeration machines. The article also demonstrates a numerical example of analyzing the parameters of compressor stations with gas turbine units based on DG-90L2.1. The research also presents the dependence of the gas turbine engine power on the air temperature and the dependence of the gas compressor unit performance on the power.
The experimental results at the compressor station confirm the preliminary calculations of the efficiency of the new gas turbine unit with an air cooling system and prove the necessity of its installation.
