我厂是一个石油加氢的炼油厂,通过加氢精制、裂化和异构反应,把蜡油分馏变为生产燃料、润滑油等最终产品的半成品原料。加氢反应在380～440℃温度、200公斤/平方厘米压力、使用各种催化剂条件下在加氢反应器内进行。因反应器是处在高温、高压下,所有气体都是易燃易爆的,且具有腐蚀性介质,故一旦在设备管理和安全维护上稍有疏忽,随时有可能在某薄弱环节出现严重事故。因此必须加强对加氢反应器的管理和检查。为此,我厂除每年一次定期设备大检修时用磁力和超声波检查筒体、焊缝表面和内部的
Our factory is a petroleum hydrogenation refinery, by hydrotreating, cracking and heterogeneous reactions, the wax fractionation into the production of fuels, lubricants and other final products of semi-finished raw materials. The hydrogenation reaction was carried out in a hydrogenation reactor at a temperature of 380 to 440 ° C and a pressure of 200 kg / cm 2 using various catalysts. Because the reactor is at high temperature and pressure, all the gas is flammable and explosive, and has a corrosive medium, so once the equipment management and maintenance of a slight negligence, at any time in a weak link may be a serious accident . Therefore, we must strengthen the hydrogenation reactor management and inspection. To this end, I plant in addition to regular annual equipment overhaul with magnetic and ultrasonic inspection cylinder, weld surface and internal
