Preparation of the corrosion inhibitor was carried out by adding the benzotriazole in sodium hydroxide solution in view of the corrosion problem of blast furnace gas condensate in iron and steel enterprises. Real-time corrosion rate of blast furnace gas condensate water with and without the corrosion inhibitor was monitored throug corrosion rate tester. The average real time corrosion rates of the blast furnace gas condensed water contacting the various dosage of the corrosion inhibitor were lower than the average real time corrosion rates without adding the corrosion inhibitor. Corrosion inhibition behavior of the corrosion inhibitor on carbon steel in the blast furnace gas condensed water using weight loss measurement method.
