摘要
由于LNG接收站在生产过程中会产生大量的天然气,氮气被作为保护气和吹扫用气使用,贯穿在各个操作环节.LNG冷能空分可以为LNG接收站供应充足的氮气,LNG冷能空分精馏塔放空低压氮气回收是一种安全可靠、经济可行的氮气供应方式,可进一步提高LNG冷能利用效率,促进节能减排和循环经济.
Abstract
Because LNG receiving station will produce a large amount of natural gas in the production process,nitrogen is used as protective gas and purging gas,which runs through every operation link.LNG cold energy air separation can supply sufficient nitrogen for LNG receiving station,and the recovery of low-pressure nitrogen from LNG cold energy air separation distillation column is a safe,reliable,economical and feasible nitrogen supply method,which can further improve the utili-zation efficiency of LNG cold energy and promote energy saving,emission reduction and circular economy.
