低温设备主要应用于煤化工、石油化工领域。在传统煤化工行业中,涉及低温设备的非常少;低温设备主要应用于现代煤化工行业当中,如甲醇制烯烃冷箱、合成氨液氮洗装置、煤制乙二醇项目、合成气、工业尾气制LNG深冷分离等。在石油化工行业,对低温设备的需求主要有乙烯冷箱、丙烷脱氢制丙烯项目、化工尾气回收等。经过多年发展,低温设备技术得到了较大发展。在现 Cryogenic equipment is mainly used in coal chemical industry, petrochemical industry. In the traditional coal chemical industry, involving very few low-temperature equipment; low-temperature equipment is mainly used in the modern coal chemical industry which, such as methanol to olefins cold box, ammonia nitrogen washing plant, coal ethylene project, syngas, industrial exhaust LNG cryogenic separation system. In the petrochemical industry, the demand for cryogenic equipment mainly includes ethylene cold box, propane dehydrogenation to propylene project and chemical tail gas recovery. After years of development, cryogenic equipment technology has been greatly developed. Now
