A process stream of dilute aqueous solution flowing at the rate of10 Kg.s-1 is to be heated. Steam condensate at 95°C is available for heating purpose, also at a rate of 10 Kg.s-1. A 1 - 1 shell and tube heat exchanger is available. The best arrangement is

Two main reasons:
1 - Steam condensate has dissolved CO2 & O2 which causes corrosion and tube side is less costly to get replaced.
2 - If we send hot condensate in the shell side we have to use insulation as it is directly exposed to ambient.

Option B is the right answer. Steam condensate has less tendency of fouling than process stream fluid.
So steam condensate must be passed through the shell side.

According to TEMA standards cold fluid is flowing through the shell side and hot fluid through tube side.

Steam is always used in shell side.

@Adrash.
In question there is steam condensate not steam.
Thank you.

Steam condensate should be used in tube side, because using it on shell side will result in more heat loss to the surrounding. Hence process stream on shell side.

The reason is that as process stream is an aqueous solution, (solvent is water) i.e. if use process steam on tube side there are enough chances of clogging, fouling of tubes as water may also contains some soluble solid impurities. So process stream should be on shell side.

It is easy to clean the tubes then the shell.

This is condensing steam so it should be on shell side for maximum heat transfer.
