FCC units have their own set of challenges when it comes to expediting entry to the fractionation system. Once the overhead reactor blind is set, the clock starts ticking. Presented in this paper are best practice strategies to quickly move from oil out to fractionator blinding along with methods and chemistries that ensure your fractionation circuit will not have LEL, H2S or CO readings. Most fractionators are packed and require two methods of pyrophoric treatment to ensure that all surfaces are treated. In addition, key changes to your shutdown procedures will allow your refinery to move from clearing to cleaning in one smooth step.
