我厂烷基化装置1973年10月14日开工生产,到1987年已连续开工生产14年,在这期间积累了一些硫酸防腐的经验。一、地面硫酸防腐从1973年开丁到1983年的十年中,由于反应器密封泄漏和循环硫酸机泵密封泄漏,使一部分硫酸流到地面和水沟,对地面和水沟造成严重腐蚀,虽曾采取过多种防腐方法,但效果均不明显。1983年初,我厂进行了硅质胶泥与花岗石耐硫酸性能的考察,经过对不同浓度的硫酸实验,发现硅质胶泥和花岗石都能耐硫酸的侵蚀。
I alkylation plant plant started October 14, 1973 production, to 1987 has been started production for 14 years, during which accumulated some sulfuric acid corrosion experience. First, the ground sulfuric acid corrosion Ding to open in 1973 to 10 years in 1983, the reactor seal leak and circulation pump seal leakage of sulfuric acid, so that part of the flow of sulfuric acid to the ground and ditches, resulting in serious erosion of the ground and ditches, Although a variety of anti-corrosion methods have been taken, but the effect is not obvious. At the beginning of 1983, our factory inspected the performance of siliceous clay and granite on sulphurous acid resistance. After experiments on different concentrations of sulfuric acid, we found that siliceous clay and granite are resistant to sulfuric acid.
