液化天然气的冷能利用研究

Study on Cold Energy Utilization of Liquefied Natural Gas

天然气作为一种清洁高效的新型能源,不仅性价比高,而且对环境造成的影响小。目前我国在液化天然气方面的研究尚处于初级阶段,生产以及应用中尚有很多不足需要解决,尤其是液化天然气的冷能利用更是当下研究的重点。基于此,总结了几种液化天然气冷能利用方法的特点,并对其中涉及的关键性技术进行了简单分析,最后基于实践经验提出了冷能利用过程中需要注意的几个方面的问题。

As a clean and efficient new energy,natural gas is not only cost-effective,but also has less impact on the environment.At present,the research on LNG in China is still at an initial stage,and there are still many deficiencies to be solved in production and application,especially the utilization of cold energy of LNG is the focus of current research.This paper summarizes the characteristics of several LNG cold energy utilization methods,and briefly analyzes the key technologies involved.Finally,based on practical experience,it puts forward several aspects that need attention in the process of cold energy utilization.
