压气站循环温升工况模拟及分析
Compressor Station Gas Temperature Circular Rise Simulation and Analysis
摘要
Abstract
Centrifugal compressors are commonly used in natural gas compressor stations for long-distance pipeline. As discharge temperature of natural gas after compressor will rise obviously, in order to prevent high temperature gas entering the pipeline which may affect the transportation efficiency and the anticorrosion layer service life, air cooler is usually provided to cool down the gas after compressor. However, in some special cases, part or all of the compressed natural gas may not be cooled down in time, and gas is repeatedly compressed in the station, so that the gas temperature continues to rise circularly. Centrifugal compressor start-up case is analyzed as a typical circular temperature rise case. By simulating and analyzing the case with ASPEN HYSYS software, it suggests that if back pressure downstream compressor is high during compressor start up, compressor speed should be increased soon to protect the piping system and keep the safe operation for compressor station.关键词
