Multifunctional Corrosion Inhibitors for oil and gas industry
The principle of protection from corrosion of our water corrosion inhibitors is the formation of very thin protective film on the anode, cathode and neutral areas of the surface. This film reliably protects the surface from chemical and electrochemical corrosion in the presence of oxygen. In case that, for any reason, the system remains without water, the protective film of our product will be stable up to 30 days and will protect against corrosion at water absence in system during this period.
removal of asphalt-resin-paraffin, mineral, mechanical depositions, corrosion products, protection of metal equipment from carbon dioxide and hydrogen sulfide corrosion at enterprises of the oil-and-gas production and processing branches of industry.
The results of corrosion studies, obtained in studying the effect of some of our developed inhibitors on corrosion of the steel 3 in circulating water on certain a refinery, are given in the table. The total volume of the unit according to water - 20,000 m³. Equipment - Carbon Steel. Water parameters: total salt content = 2057 mg / dm³, including - chloride = 298 mg / dm³, sulfate = 484 mg / dm³, pH = 7.87, hardness = 15.3 mg • eq / dm³, alkalinity = 2.3 mg • eq / dm³, the oil content - 91 mg / dm³, content of suspended solids = 49 mg / dm³.
