压缩机组是压气站的核心组成部分,同时也是天然气输气干线中的主要工艺设备,主要由压缩机本体和驱动机构成。近年来随着我国天然气输气干线建设呈现出的跨越式发展,压缩机组的保有量和需求量都在迅速增加,而在压缩机组的选用上,则需要综合考虑周围环境、功率要求以及经济性评价等要素,并对功率大小、备用方式和驱动方式等进行比选。本文结合工作实际,主要对国内天然气输气干线压气站压缩机组的选型进行了研究与探讨,希望能对压缩机组的实际选型提供一定的决策支持和技术参考。
The compressor unit is the core component of the compressor station and also the main process equipment in the natural gas transmission line, which is mainly composed of the compressor body and the driving machine. In recent years, with the leaping development of the construction of natural gas transmission lines in our country, the holding capacity and demand of compressors are increasing rapidly. However, in the selection of compressors, the surrounding environment, power requirements and economy Evaluation and other factors, and the size of the power, backup and driving methods such as comparison. Based on the actual work, this paper mainly studies and discusses the selection of compressor units for gas compressor stations in China, hoping to provide some decision support and technical reference for the actual selection of compressor units.
