天然气是一种清洁能源,现在已经成为我国社会发展中的一种重要能源,天然气的消费量不断增加,而液化天然气是天然气利用的一种重要形式,是边远气田气体利用、城市燃气调峰的一种重要举措。天然气液化的工艺一般有两个环节,也就是净化处理与制冷循环。本文主要根据现有的研究资料和自身的工作经验,探讨天然气液化的工艺方法及选定,希望能够对企业天然气液化生产提供一点帮助。
Natural gas is a kind of clean energy. Now it has become an important energy source in China’s social development. The consumption of natural gas is increasing. LNG is an important form of natural gas utilization. It is the utilization of gas in remote gas fields and the peaking of city gas An important move. Natural gas liquefaction process generally has two links, that is, purification and refrigeration cycle. In this paper, based on the existing research data and their own work experience, this paper discusses the natural gas liquefaction process and selection, hoping to provide some help to the enterprise liquefaction production.
