shell type selection

[rezapayman]

Dear Friends
I am working in an oil and gas Industry.I always asked to design specific type of Exchanger (like AES)due to thermal requirements.I would like to learn how does a Heat exchanger designer select shell types for his requirement? divided flow or two pass shell?split flow or kettle type?
Do you know a useful references for this reason?
best wishes

dear ,
type of exchanger depend upon which type fluid is used. to study this you may refer TEMA or LUDWIG volume-3.

Usually the customer(user) specifies the type of heat exchanger. Normally his process engineer determines if a vaporizing service should be a kettle or not.

The heat exchanger designer decides on the configeration. If there is a shell side pressure drop problem, then divided flow, double or triple segmental baffles are used. If there is a temperature cross (t2 -T2), then 2 shell pass split flow or double split flow could be used.

There are many other options the heat exchanger designer has available to him/her.
