Multifunctional corrosion inhibitors due to their unique physical and chemical properties are successfully applied at gas and oil producing enterprises – for the corrosion protection of
oil and gas gathering systems
intra- and inter-field pipelines
and also for the removal of ARPD

Pipelines in the oil and gas companies are used to transport oil, gas condensate, gas and petroleum products. The transported fluid normally contains aggressive components (water, hydrogen sulfide, carbon dioxide, oxygen) that lead to corrosion of metal surface in the pipeline. The result of corrosion of oil pipeline is reducing the thickness of pipe walls, stress cracking of the metal, sedimentation of corrosion products on the metal surface of the pipeline, which in turn reduce the performance of the pipeline, contamination of the transported fluid with corrosion products, pipeline leakages and oil losses, pipeline ruptures and large economic and environmental losses for oil and gas companies. Crude oil pipeline should be protected from the negative impact of corrosion. The most simple and suitable method for the corrosion protection of inner surfaces of pipelines, reservoirs, tanks, equipment of the injection pump stations, etc., and also for the removal of asphalt-resin-paraffin depositions is using of polyfunctional corrosion inhibitors.

Tankers - for corrosion protection of internal metal walls of the vessel for the carriage of petroleum and petroleum products. The presence of corrosive aggressive sea water medium with dissolved gases, salts in the hydrocarbons during their transportation leads to corrosion of the tanker. The application of a corrosion inhibitor can significantly reduce the rate of corrosion of the metal and significantly extend the life of the transport ship.
Currently, oil and gas treating enterprises use corrosion protection of metal equipment, in which the corrosion inhibitors are used as the most simple and effective method.
Multifunctional corrosion inhibitors help protect facilities at oil and gas treating enterprises from corrosion:
including gas processing plants (GPP)
unified oil treatment plant (UOTP)
gas complex treatment plant (GCTP)
crude preparation plants (CPP)
gas fractionation plants (GFP)
This increases the lifetime of the foregoing facilities and in general significantly improves their reliability and capacity.
Units of primary oil refining are the basis of any refinery. They are intended for the basic oil fractionation from which further oil products are obtained. Therefore, operation of all subsequent production facilities at the refinery depends on the performance and reliability of primary oil processing plants. The corrosion of metal equipment is determined by the composition of the incoming raw materials for processing at the refinery, which may contain small amounts of aggressive corrosive components (water, hydrogen sulfide, carbon dioxide), which lead to corrosion. A feature of corrosion protection of refinery equipments is that of refining processes carried out at high temperatures. This requires a special approach and a careful selection of high-temperature corrosion inhibitors to protect against corrosion of metal equipment at the refinery (condensation and refrigerating equipment of crude oil distillation units.).
