我厂为燃料油型加工厂,原油主要来源于四大油田,由于原油性质多变,很难掌握设备腐蚀情况,在84年我厂又增炼了辽河原油。由于辽河原油含环烷酸量高,对工艺设备的腐蚀又带来了新的问题。为了解决加工辽河原油环烷酸对设备的腐蚀问题,结合我厂具体情况,参考了国外炼厂对加工环烷酸含量高的原油所采取的防腐措施,并吸取了国内兄弟厂加工辽河油的经验和教训,在85年停工检修中,对我厂加工辽河油关键性部位的工艺设备进行了改造。 Our factory is a fuel oil processing plant. Crude oil mainly comes from the four major oil fields. Due to the changeable nature of crude oil, it is difficult to grasp the corrosion of equipment. In 1984, our plant further refined Liaohe crude oil. Liaohe crude oil due to the high amount of naphthenic acid, the corrosion of process equipment has brought new problems. In order to solve the Liaohe crude naphthenic acid corrosion of equipment, combined with the specific circumstances of our plant, with reference to foreign refineries naphthenic acid processing high crude oil anti-corrosion measures taken, and learned from the domestic brother plant processing Liaohe oil Experience and lessons learned, in the 85-year suspension of maintenance, I plant processing Liaohe oil key parts of the process equipment has been transformed.
