So the methods of preventing and reducing carbon dioxide corrosion have become a widely focused problem. The foreign and domestic practices and experiences show that as an economic, effective and versatile metal corrosion control method, corrosion inhibitor protection technology is suitable for application in oil and gas transportation system. This paper, through the indoor experiment with benzyl chloride, using quinoline as raw materials, synthesizes a kind of quinoline quaternary ammonium salt. The obtained product benzyl chloride quinoline compounded with OP-10 and ethanol to get a novel inhibitor DN for carbon dioxide corrosion, and to evaluate its performance.展开更多

The scale and corrosion inhibitions of PASP was evaluated and compared with 2-phosphonobutane-1,2,4-tricar- boxylic acid(PBTCA), 1-hydroxyethylidene-1,1-diphosphonic acid(HEDP) and hydrolyzed polymaleic anhydride(HPMA). The results revealed that the inhibition of the PASP is close to that of PBTCA and HEDP, but much better than that of HPMA.展开更多
