我国首台大型化工高压容器105-D卧式氨合成塔外壳在第二重型机器厂研制成功,于1990年2月26日通过国家鉴定。105-D卧式氨合成塔外壳,是国家“七五”重点建设项目——四川化工总厂年产30万t合成氨技术改造工程的关键设备。长22m,直径2.4m,重184.4t。这种大型化工设备,制造工艺复杂,技术难度很高,目前世界上只有少数工业发达国家才有能力制造。
China’s first large-scale chemical high-pressure vessel 105-D horizontal ammonia synthesis reactor shell was successfully developed at the second heavy machine factory and passed the national appraisal on February 26, 1990. The 105-D horizontal ammonia converter tower is the key equipment for the national “Seventh Five-Year Plan” key construction project - Sichuan Chemical Plant’s annual output of 300,000 tons of synthetic ammonia technology transformation project. Length 22m, diameter 2.4m, weight 184.4t. This kind of large-scale chemical equipment has complicated manufacturing processes and high technical difficulty. At present, only a few industrialized countries in the world have the ability to manufacture.
