Abstract
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.
