Discussion on fluctuations in tower top corrosion protection
Thread Content
Anti-corrosion for atmospheric and vacuum distillation units; the original anti-corrosion measures were effective, including alkali injection at the tower top and injection in the first stage of separation. After processing the Liuhua oil once, it was switched back to Qinhuangdao, where processing usually takes place; the level of iron ions at the top of the tower fluctuated greatly. Several attempts at adjustment were unsuccessful, and the chloride level increased from 50 to over 200. Please help analyze the reasons
After changing the crude oil, it is necessary to re-establish a film at the tower top; after the change in crude oil, the amount of injection fluid should be increased to 200% of the original level. After about a week, operations will return to normal, and the injection volume can then be adjusted back to its normal value； 【Production in Summer】---- The production area enters the \"train during the hot summer days\" mode http://bbs.hcbbs.com/thread-1421676-1-1.html
