Organochlorine production/chlorine-organic compounds (COC)
An important aspect related to the sources of the appearance of COC in oil is noted, namely, one of which is natural, determining some components of crude oil, and the other source is chlorine-containing oilfield reagents used at various stages of oil production, transportation and preparation, as well as products of their thermal and chemical transformations. It is assumed that the formation of COC can occur as a result of hydrochloric acid treatments, hydrolysis of chloride salts, and the interaction of oil components with hydrochloric acid
