The kinetics of naphthenic acid corrosion in Liaohe crude oil to carbonsteel were studied. The effects of temperature and acidity on corrosion rate ofcarbon steel were investigated. Four isotherms were obtained, just as BET equa-tion which can be used to predict the corrosion rate of carbon steel.The apparent reaction rate constant and activity energy were obtained, too.Based on the experimental results, three adsorption-corrosion postulates werepresented, the isotherms and the effects of fluid velocity on ...
