摘要
简要分析了目前世界上较成熟的几种LNG液化技术及国内应用情况,重点研究了陕西定边一期92万m3/天LNG工厂三段混合制冷液化技术及运行情况。一年来的运行实践证明,采用这种液化技术可靠性高、可操作性强、开停机过程容易,经济适用,有明显的优势,非常适用国内LNG发展需要,适合国情。
The article analyse briefly mature liquefaction technology of LNG in the world , and focuse on the three-cascade Mixed-Refrigerant Cycle liquefaction technology and its application in dingbian county , shanxi province (Ⅰ) , For more than a year in practice it has proved that thisliquefactiong technology is high reliability 、 easy op-eraion、 economic operation、 quick start and stop and quick load regulation , it has a obvious advantage as coM-Pared to other liquefaction technology , which better suits the actual conditions of China.
