24.
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
counter flow with process stream on shell side.
counter flow with process stream on tube side.
parallel flow with process stream on shell side.
parallel flow with process stream on tube side.
Answer: Option

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.
