I took a heavy end (FO grade) material with Pour Point (PP) of 30 Deg C and blended it with Light cycle oil (LCO) from FCCU having PP of 6 deg C. LCo was only 20% of the total blend.
The PP of the blend was lab tested and found to be only 6 deg C. theroetical blend cal results shows PP of 18...
I would like to know how to avoid a temp cross over in a simple heat exchanger. I read adding more shells like 2-4 instead of 1-2 can be a way. But i didnt understand how. can someone explain.
thanks in advance
