据石油化工企业资料,由于加工的原油含氯量偏高,生产的石脑油产品氯含量严重超标,甚者致使炼油厂常减压装置的常压塔顶空冷器泄漏、芳烃联合装置重整换热器腐蚀穿透,造成介质相混,重整催化剂中毒,为了安全生产不得不停工抢修,常减压装置也不得不边生产边更换空冷器。 为什么会发生这种情况呢?笔者认为主要有两方面原因。一方面,随着国家对石油需求量的不断增加,对稠油、高凝油、低渗透油的开采愈来愈多,采用化学药剂来降粘、降凝、清蜡、解堵、破乳等方法也愈来愈多。这是因为化学药剂对于原油的开采和集输是有利的,
According to the information of petrochemical enterprises, due to the high chlorine content of the processed crude oil, the chlorine content of the naphtha products produced exceeds the standard seriously, which leads to the leakage of the atmospheric pressure overhead air cooler of the atmospheric and vacuum distillation unit of the refinery and the reforming of the aromatics complex Heat exchanger corrosion through, resulting in mixed media, catalyst reforming poisoning, in order to work safety had to suspend repair, atmospheric and vacuum unit also had to replace the production side of the air cooler. Why does this happen? I think there are two main reasons. On the one hand, with the continuous increase of oil demand in our country, the exploitation of heavy oil, high pour point oil and low permeate oil is more and more. Chemical agents are used to reduce viscosity, pour point depressant, dewax, And other methods are also more and more. This is because chemicals are advantageous for the exploitation and gathering of crude oil,
