Assessment of Energy Efficiency of Sections of a Gas-Transporting System with Replaced Flow Passages of Centrifugal Compressors Having Reduced Rated Pressure Ratio

  • Published:
Chemical and Petroleum Engineering Aims and scope

The functioning of sections of a gas transporting system through which the gas is transported at low pressure with reduced compression ratio (compared to the rated ratio of 1.44) at compressor stations is analyzed. The results of assessment of energy efficiency indices of these sections of the gas transporting system for two options, namely, with replacement of flow passage (RFP) in centrifugal compressors of GPA-Ts-16 gas pumping units and without replacement of flow passage (as at present) are presented. The influence of technological risks on the indices is assessed. The results of the study have provided economic criteria that allow confirmation of the expediency of the steps taken for replacing flow passages of centrifugal gas compressors of the studied sections of the gas transporting system with reduced pressure ratio.
