To enhance oil recovery from reservoirs, various chlorinated organic compounds (COCs) are used, such as carbon tetrachloride, dichloroethane, chloroform, tetrachloroethylene, etc. These are artificial additives and are not naturally present in crude oil. COCs are not dangerous during the transportation of crude oil, but they cause significant damage during its processing.

In the production of commercial petroleum products at refineries (distillation, hydrotreating, reforming), most of the organically bound chlorine is transformed into hydrogen chloride (HCl). An aqueous solution of hydrogen chloride is aggressive hydrochloric acid, which corrodes expensive industrial equipment. Therefore, at every stage of oil production, transportation, and processing, it is necessary to monitor the content of COCs.

To address the problem of determining chlorinated organics in crude oil, the Scientific and Technical Firm “BAKS” has developed a unique analytical complex.
