炼制辽河原油的炼厂,在蒸馏装置的加热炉炉管、转油线、塔的进料段等高温部位发现了严重的设备腐蚀问题,习惯上称这种腐蚀为“高温腐蚀”.以往.人们认为辽河原油的高温腐蚀是由环烷酸(应当称为石油酸引起的.我们考察了各种腐蚀介质的作用,发现石油酸钓是腐蚀过程的促进剂,它可使石油酸和H_2S的腐蚀作用增大数倍. Refining Liaohe refinery crude oil, distillation equipment in the furnace tube, turn the oil line, tower feed section and other high temperature parts found serious corrosion of equipment, used to call this corrosion as “high temperature corrosion.” In the past It is believed that the high temperature corrosion of Liaohe crude oil is caused by naphthenic acid (which should be called petroleum acid.) We examined the role of various corrosive media and found that petroleum acid flotation is an accelerator of the corrosion process, which can make petroleum acids and H 2 S The corrosion effect increases several times.
