1 前言目前,在我国现役加氢装置的反应器和热交换器中,部分仍是日伪时期建制的,距今50余年.为考察这批设备继续运行的安全性,我们对某厂部分加氢设备进行检验,并在一台同期制造现已报废的反应器上取样,进行试验观察、分析,结果供参考。 2 加氢反应器原始状况有关资料记载,此反应器1939年至1959年原用作电热筒,内部氢压为21.6MPa,进、出口温度分别为340℃和400℃,在此期间未发现裂纹。1959年开始作反应器使用,筒内压力为20.3MPa,氢压为17.65MPa。筒内介质除氢外,还有油类、硫化铂催化剂及少量的CH_4、Cl_2、CO、H_2S、水蒸气等。其中H_2S含量约为0.1～1%。反应器壁温为300～320℃、介质温度
1 Preface At present, some reactors and heat exchangers of active hydrogenation plants in our country are still partially built during the period of Japanese Puppet War, more than 50 years ago. In order to examine the safety of the continuous operation of these facilities, Hydrogen equipment for testing, and in the same period has been scrapped reactor manufacturing sampling, experimental observation, analysis, the results for reference. 2 Hydrogenation reactor original state information records, the reactor from 1939 to 1959 was originally used as electric tube, the internal hydrogen pressure of 21.6MPa, inlet and outlet temperatures were 340 ℃ and 400 ℃, no cracks were found during this period . Reactor used in 1959, the pressure inside the cylinder is 20.3MPa, hydrogen pressure is 17.65MPa. In addition to hydrogen inside the barrel, there are oils, platinum sulfide catalyst and a small amount of CH_4, Cl_2, CO, H_2S, water vapor and so on. H 2 S content of which is about 0.1 to 1%. Reactor wall temperature of 300 ~ 320 ℃, medium temperature
