Hi everyone,
I am doing a project on production of syngas from rice husk gasification. the gasifier design has been done. now i have to design a heat exchanger to lower the temperature of syngas to 55 C.
I previously simulated a shell and tube heatx on aspen. The syngas enters the exchanger at 800 C and leaves at 55 C. the cooling fluid is water (in shell side) entering at 25 C and leaving at 100C with 0.46 Vapor fraction. The exchanger has 51 tubes in three passes with an area of 4.6 sqm.
I want to know if the said shell and tube heatx is feasible? or should i consider using 2 or 3 exchangers in series. Or should i use Kettle Reboiler to cool down syngas?
I couldn't find any informative source to help me learn Kettle Reboiler design using aspen plus software.
Thanks
