一.大型空分设备内压缩工艺流程技术的开发研制背景:90年代以前,国内空分设备制造厂家一般采用的技术均是全低压流程,氧气以接近大气压的压力送出冷箱,然后再通过产品气压缩机组将氧(氮)气加压至所需压力。因此按传统的工艺流程生产的成套空分装置存在着以下不足: A large air separation plant compression process technology development background: 90 years ago, the domestic air separation plant manufacturers are generally used technology is the whole low-pressure processes, oxygen at nearly atmospheric pressure out of the cold box, and then through the product The gas compressor unit pressurizes the oxygen (nitrogen) gas to the desired pressure. Therefore, according to the traditional process of production of air separation unit sets the following deficiencies:
