| Abstract: | Synthesize a novel pyridine quaternary corrosion inhibitor. Studied and discussed the pyridine quaternary corrosion inhibition perlbrmance about Q235 steel in the 1000 ppm HCI and 500 ppm H2S solution in the air cooler, water cooler of the oil refining unit tower. The compatibility of the pyridine quaternary, organic amines, surfactants. The research show that： pyridine quaternary attains better inhibition on the corrosion of Q235 steel than imidazoline quaternary. After adding 20 ppm quaternary pyridine inhibition efficiency can reach 90 %. Corrosion of Q235 steel showed significant inhibition. |
