HIMIPEX Company has developed corrosion inhibitors of DEFENDER series that were successfully tested at a gas condensate field of the oil-and-gas producing enterprise in Asia.
Dosage: 20–40 g of inhibitor per 1000 m3 of gas (while using the method of “shock” dosages). Problematics of the facility:high corrosion rates of pumping and compression pipes (production tubing) stimulated by high content (above 5%) of carbon dioxide (CO2) in the system.
High efficiency of the inhibitor (deceleration of corrosion rate amounted to 10–12 times). After feeding of the inhibitor “shock” dosage and stabilization of protective film of the corrosion inhibitor on the surface of pumping and compression pipes (production tubing), the inhibitor dosage was reduced to 10–20 g/1000 m3 of gas. The slowdown of corrosion damages of equipment, including damages caused by local types of corrosion in stratal water amounted to more than 90%.
