摘要
随着液化天然气在全球范围内需求量的增加,对其气化后所产生高品质冷能的利用,是各个国家特别是发达国家竞相追逐的对象。对冷冻法海水淡化和LNG冷能结合冷冻法趋势进行讨论,分析了各种工艺的优缺点以及应用前景,提出了LNG冷能冷冻法与膜法联用是目前利用LNG冷能淡化海水的最适合方法。
With the increasing demand for liquefied natural gas（LNG） in the whole world ,the utilization of the high- quality cold energy which is produced from the gasification of LNG has been the object pursed by all countries, esp. the developing countries. The tendency of freezing method which is a combination of desalination and LNG cold ener- gy is discussed. The advantages and disadvantages of various technologies and their application prospect lyzed. It is proposed that the LNG cold energy freezing method combined with membrane method is the most method for the application of LNG cold energy to desalination. are ana- suitable
