Hello everyone,

 

I am senior chemical engineering student.Right now we are working on design project which is lpg design. We chose the natural gas fractination with the turboexpander cooling. The problem is that refrigeration.The best option in internet is plate fin type but we can't use in our simulation and we used shell and tube heat exchanger. Is it okay to you use ethylene,nitrogen,co2 refrigeration in shell and tube.The system is very complex

Shell and tube exchanger is okay. This should be easier for you to model. The turboexpander is the key part of the system and probably will be the trickiest if you have no go-by.
