| Abstract: | s: The analysis of the salt depositing on the overhead of heavy oil FCC main fractionator concluded that the heavier feedstocks of the upgrading units and increase of the impurities like chloride, sulfur and nitrogen etc were the culprits. The salt depositing could be prevented by strengthening "one removal and three injections", applying new catalyst and improving the corrosion monitoring. |
