段贤琪等·改进CNG子站工艺流程提高加气量
改进CNG子站工艺流程提高加气量乌鲁木齐市鑫泰燃气有限责任公司（831400）段贤琪徐辰天
摘
要：CNG子站管束气瓶中的天然气经卸气柱后增设一路管线直接进入加气机低压系统，利用管束
气瓶中天然气自身压力对CNG汽车加气，而后加气机电磁阀自动切换对CNG汽车加中、高压气，直至加气完成。加气量中三分之一天然气不经过压缩机压缩，减少了机器磨损，降低了能耗，缩短管束气瓶的气时间，提高CNG子站加气量约50%。

Abstract : Set up a pipeline direct access to low pressure system of gas dispenser after natural gas in bundle type cylinder
went through the discharge gas column, and use the selfpressure of natural gas in bundle type cylinder to fill the CNG vehicle, then the electromagnetic valve in gas dispenser switch midpressure to highpressure until the gas filling completed. The onethird of gas add volume was not pass through the compression engine, so that reduced wear rate, energy consumption and gas discharge time of bundle type cylinder. It can increase about 50% gas fueling capacity.

安全、气象条件等因素，长期运营的LNG接收站宜采用岸上接收方式，尤其是需要燃气储量较大时通常采用岸上接收方式。
（3）综合考虑建设周期和建设规模，海上LNG
接收站可作为岸上LNG接收站的过渡。万方数据
