摘　　要：长输天然气管道作为重要的能源运输工具,在保障安全高效性输送的同时,全面拉动了我国天然气城市化进程。国内处理管道泄露问题时,通常先放空管道内天然气再进行抢修工作,这样就造成了对天然气的大量浪费。设计了一套对长输管道放空天然气进行回收的车载压缩机组,并进行经济可行性分析。当发生泄露后,车量迅速到达截断阀室现场,将泄露段天然气回收注入至下一段管道,既节约能源,又减少了由于放空天然气带来的环境污染。As important energy transportation means, the long-distance natural gas pipeline promotes the natural gas urbanization process in China as it can ensure safe efficiency natural gas transmission. When dealing with the problem of pipeline leak in China, natural gas in the pipeline is usually vented before carrying out the repair work,which can cause a lot of waste of natural gas. A set of vehicle compressor was designed, it can recover natural gas in long distance pipeline, and its economic feasibility was analyzed. When a leak occurs, recycling car will quickly reach the cut-off valve room scene, recycle natural gas of leak section and inject it into the next section of pipeline. It can save energy, and reduce the environmental pollution caused by venting natural gas.
