Component composition of dissolved organic compounds of sewage water of uzen’ oilfield

The composition of extracts of volatile dissolved organic compounds of the wastewater of the Ozen oilfield was studied by chromatography-mass spectrometry (GC/MS). It has been established that the main components are hydrocarbons. It should be noted the presence in the water of benzyl chloride (benzene chloride) -1.3%, the content of which is strictly regulated in oil. A low content of organic acids (palmitic acid) is observed. It should also be noted the presence of tertiary N, N-dimethyldodecanamine (C-12) upto 2.3% and N, N-dimethyltridecanamine (C-13), which are components of corrosion inhibitors. The presence of xylene, mesitylene, 1,2,3-trimethylbenzene and 2,6-dimethylnaphthalene indicates the possible use of the demulsifier type Tretolite. A significant amount of squalene, which is a natural biomarker of oils has also been discovered.
