压缩天然气加气站天然气回收利用方法
摘要：
本发明涉及一种压缩天然气加气站天然气回收利用方法，主要解决现有技术中天然气浪费、污染环境的问题。本发明通过采用一种压缩天然气加气站天然气回收利用方法，从回收管线来的天然气经集气总管后分为至少两路，一路经放空管线放空，另一路进入缓冲罐，从缓冲罐出来的天然气进入压缩机；当回收管线压力降低到与压缩机前的气体管线压力一致时，放空管线控制阀门打开，天然气放空的技术方案较好地解决了上述问题，可用于压缩天然气加气站中。
摘要（英）：

The invention relates to a natural gas recycling method for compressed natural gas stations, and mainly solves the problems that in the prior art, natural gas is wasted and environmental pollution is caused. The natural gas recycling method well solves the problems by adopting the technical scheme that natural gas from a recycling pipeline is divided into at least two paths after passing through a gas collecting main pipe, one path is emptied through an emptying pipeline, the other path enters a buffer tank, the natural gas from the buffer tank is fed into a compressor, and when the pressure of the recycling pipeline is reduced to be consistent with that of a gas pipeline in front of the compressor, a control valve of the emptying pipeline is opened to empty the natural gas. The method can be applied to compressed natural gas stations.
