As the title suggests: What is the impact of the length of catalytic stripping time on coke yield?
Reply to 1# 328104062: Coke is mainly composed of additional carbon, catalytic carbon, contaminated carbon, and steamable carbon. Controlling the inventory in the stripping section of the settler at a higher level can extend the stripping time and improve the stripping efficiency (with an adequate amount of stripping steam, typically 0.35% of the catalyst circulation rate), thereby reducing the amount of carbon that can be stripped and lowering the coke yield.
