在燃料型炼厂中为提高拔出率,增加催化原料,干式减压蒸馏新技术得到广泛推广。唯含硫高的原油中,对填料的腐蚀严重,影响了新技术的应用。中国石化总公司洛阳石油化工工程公司设备研究所为此进行了工业挂片和模拟试验。试验的腐蚀环境为:1.低温 HCl-H_2S-H_2O 系统2.高温 H_2S3.有环烷酸—高温硫化氢的系统通过几年的试验,得出的结果是:对于以江汉原油、南阳原油、胜利原油
In fuel-type refinery to increase the pull-out rate, increase the catalytic raw materials, dry vacuum distillation of new technologies have been widely promoted. Sulfur-rich crude oil, the serious corrosion of the filler, affecting the application of new technologies. China Petrochemical Corporation Luoyang Petrochemical Engineering Equipment Institute for this study carried out industrial hangs and simulation tests. The corrosive environment of the experiment is as follows: 1. Low temperature HCl-H 2 S-H 2 O system 2. High temperature H 2 S 3. The system with naphthenic acid-high temperature hydrogen sulfide passed the tests for several years and the result is as follows: For Jianghan crude oil, Nanyang crude oil, Victory crude oil
