据《中国化工报》2008年4月11日报道,合肥通用机械研究院等单位经过3年研究攻关,最近首次成功研制并建造了具有自主知识产权的大型低温乙烯球罐。乙烯球罐是乙烯裂解装置中关键的存储设备,使用时操作压力高,温度低,安全性要求高,需设置可靠的保冷装置。这使乙烯球罐在设计、选 According to “China Chemical Industry News” reported on April 11, 2008, Hefei General Machinery Research Institute and other units after three years of research and development, the first successful development for the first time and built a large-scale low-temperature polyethylene balloon with independent intellectual property rights. Vinyl tank is ethylene cracking unit in the key storage device, the use of high operating pressure, low temperature, high safety requirements, the need to set up a reliable cooling device. This makes vinyl ball cans in the design, choose
