压缩天然气(CNG)加气母站的工艺设计方案

Process Design Scenario of Compressed Natural Gas (CNG) Automobile Parent Fuelling Station

阐述了压缩天然气(CNG)汽车加气母站工艺设计方案的确定原则。以前置脱水为例,介绍了CNG加气母站的工艺流程,结合《车用压缩天然气》(GB18047-2000)标准,分析了两种深度脱水方案的优缺点以及脱水方案的确定方式。从占地面积、安全性、使用年限等六个方面对小瓶储气、大瓶储气、储气井储气三种储气方案的优缺点进行了比较。着重介绍了CNG加气母站必备的各系统的构成及其功能。

The decision-making guideline of process design scenario of compressed natural gas(CNG)automobile parent fuelling station is described.Take the pre-dehydration technique of gas as an example,the paper gives the process flow of CNG automobile parent fuelling station.According to the Code of GB18047-2000(Compressed Natural Gas for Automobile Use),this paper compares and analyzes the scenario of strengthening dehydration and determination method of dehydration of natural gas.For the CNG automobile parent fuelling station,the 3 gas storage manners,small-volume steel tank,large-volume steel tank and gas storage well,are compared from the earth making-up,safety and service life and so on.Meanwhile,the constitution of necessary operating system and their functions for this kind of station is introduced.
