利用天然气管网压力能生产LNG技术研究

Research on the Production of LNG by Pressure of Natural Gas Pipeline Network

我国在天然气高压输送方面取得了长足的发展,在天然气管道的高压输送的过程中,长输管线在调整压力时必然会损失大量的压力能,利用天然气官网压力能也自然而然的引起了人们广泛关注,天然气管网压力能对于LNG技术的生产有着重要意义。因此,论文从利用天然气管网压力能生产LNG技术研究的意义出发,对天然气管网压力能进行分析,最后阐述了基于联立模块法压差液化工艺选择,希望对利用天然气管网压力能生产LNG技术方面工作有所帮助。

China has made great progress in the high-pressure transmission of natural gas. During the high-pressure transportation of natural gas pipeline, the long-distance pipeline will inevitably lose a lot of pressure energy when adjusting the pressure, and using the pressure of natural gas will also cause people's attention. The pressure of natural gas pipeline network can be of great significance to the production of LNG technology. Therefore, this paper analyzes the pressure energy of natural gas pipeline network from the view of using energy of natural gas pipeline network to produce LNG. Finally, it expatiates on the choice of differential pressure liquefaction process based on simultaneous module method, hoping to provide reference to this technology.
