我厂蒸馏(Ⅰ)装置1979年建成投产,在1990年对其进行大规模改造后,成为全国少有的几套以环烷基原油为原料生产滑油的装置之一,该原料粘度大,密度大,腐蚀性强。虽然采取了不少防腐措施,但通过近10年来的运行发现,整套装置腐蚀十分严重。为此厂里将蒸馏(Ⅰ)列为重大安全隐患对象之一,制定出了严格的巡检制度,彻底避免了2000年12月份、2001年2月份、2001年5月份发 I plant distillation (Ⅰ) plant put into operation in 1979, after its large-scale transformation in 1990, became the country’s few sets of naphthenic crude oil as a raw material for the production of oil one of the devices, the raw material viscosity, Density, corrosive. Although a lot of anti-corrosion measures have been taken, it has been found through the operation of the past 10 years that the corrosion of the whole set of equipment is very serious. As a result, distillation (Ⅰ) was listed as one of the major hidden dangers for safety in the factory and a strict inspection system was formulated to completely avoid the problems of December 2000, February 2001 and May 2001
