七十年代,法国NAT公司发展了一种新型膨胀制冷机——热分离机。这种膨胀机属于做外功的膨胀制冷机,但与活塞式和透平式膨胀机相比,结构简单,制冷部分无运动部件,具有抵抗二相流侵蚀的能力,特别适用于气体分离。日本三菱重工业公司引进法国NAT公司的技术,制造出了用于化工尾气及石油伴生气的分离回收装置。国内的浙江大学、大连工学院及营口石油化工研究所等,通过多年的努力,亦研制了这种新型制冷机,并且对其结构、制造工艺及性能改进做了大量工作,将该机的等嫡效率提高到60％以
Seventies, France NAT company developed a new type of expansion refrigerator - hot separator. This type of expander belongs to an expansion refrigerator that performs external work. However, compared with piston-type and turbine-type expanders, the structure is simple and has no moving parts in the refrigeration section. It is capable of resisting the erosion of two-phase flow and is particularly suitable for gas separation. Japan’s Mitsubishi Heavy Industries to introduce the French NAT company’s technology to create a chemical waste gas and oil associated with the separation of gas recovery unit. China’s Zhejiang University, Dalian Institute of Technology and Yingkou Petrochemical Research Institute, through years of efforts, also developed this new type of refrigerator, and its structure, manufacturing processes and performance improvements have done a lot of work, the machine and so on嫡 efficiency increased to 60%
