前言存在于石油中的酸性物质统称为石油酸,其中环烷酸的含量又占90%以上。当原油酸值超过0.5mgKOH/g时,就会在200～400℃下产生环烷酸腐蚀;在270～280℃时产生环烷酸腐蚀的第一个高峰;在340～350℃出现第二个腐蚀高峰;在400℃以上观察不
Preface The acidic substances present in petroleum collectively referred to as the oil acid, which naphthenic acid content accounted for more than 90%. When the crude oil acid value exceeds 0.5mgKOH / g, it will produce naphthenic acid corrosion at 200-400 ℃; produce the first peak of naphthenic acid corrosion at 270-280 ℃; secondly appear at 340-350 ℃ A peak of corrosion; not observed above 400 ℃
