在原油中,一般含有硫化物、氯化物、氮化物和有机酸等。在原油加工过程中,因加热分解,生成多种腐蚀产物,使装置设备发生腐蚀。另外,加氢装置在使用触媒的条件下.发生分解、转化、脱硫等反应。氢在高温高压下引起各种危害。在本文中,阐述了石油工业,特别是炼油设备的腐蚀以及腐蚀环境。一、Hcl—H_2s—H_2o腐蚀系统该腐蚀发生在常压蒸馏装置的蒸馏塔顶冷凝冷却过程。(i)生成氯化氢:原油中的氯化物
In crude oil, it generally contains sulfides, chlorides, nitrides and organic acids. In the process of crude oil processing, due to heat decomposition, generate a variety of corrosion products, the device equipment corrosion. In addition, under the condition of using a catalyst, the hydrogenation unit undergoes reactions such as decomposition, conversion and desulfurization. Hydrogen causes a variety of hazards at high temperatures and pressures. In this article, we describe the corrosive and corrosive environment of the oil industry, especially the refinery. A, Hcl-H_2s-H_2o corrosion system The corrosion occurred in the atmospheric distillation unit distillation overhead condensation cooling process. (i) Hydrogen chloride generation: Chloride in crude oil
