The FCC unit, sulfur recovery unit (SRU) and delayed coker unit (DCU) operations training at RefComm® Bahrain 2015 took place the week of November 8 – 12 (see www.refiningcommunity.com/refcomm-bahrain-2015). Great lessons were learned and shared among Middle Eastern refinery personnel assigned to some of the newest high-complexity refineries in the world. Everyone knows that starting up a new coker, FCC, or sulfur unit can be a challenge. Learning from others’ experiences is the way to improve.
A new idea that was shared during the coker training may have widespread use for DCU based refiners… and it is nearly free. It was noted that a certain refinery has coke carry-over from the drum due to very small outages. They manage the coke fines in the fractionation; wrapping the standpipe in large mesh screen (about 1″ openings). With this addition, they were able to extend fractionator cleaning intervals from 6 months to 1 year. This may not seem like much to plants that run 5 years or more but this could be an easy way to protect the furnace charge pump — a win-win for everyone.
