Genesis of Organochlorine Compounds in Crude Oil and Petroleum Products (A Review)

“…It is well-known that at high refining temperatures, the presence of OCCs in crude oil results in the formation of hydrogen chloride [3]. This accelerates the corrosion of refinery pipelines and equipment, and contributes to the deactivation of refining catalysts [4][5][6]. In addition, hydrogen chloride reacts with ammonia from the hydrogenation of nitrogen compounds, thus producing ammonium chloride; this also leads to refinery equipment failures [7,8].…”
