Q & A > Question Details
I'm a process engineer at a CCR unit. Recently we have huge amount af gas formation because of extreme cracking, and RONC is 97 with total delta t equal to 218 deg c,WAIT=509, EDC IS 0.9 LIT/HR without water injection and our water content in platrecycle gas is out of service! I guess there is a chloride/water imbalance, but I want to reduce cracking reactions to increase RONC so can I have your recomendations please?

Before you can get sound recommendations to cure your problems, you need to provide much more data about your unit.
Just a short list which data are essential:
-recyclegas rate and purity (better composition)
-gasproduction quantity
-LPG production quantity
-stabilizeroffgas quantity and composition
-chloride content on regenerated catalyst
-carboncontent on spent catalyst
-do you add EDC to the feed or only to the regenerator
-a simple prescription about your unit setup
-all quantities as wt%
-feed composition N+2A and destillation
