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_______________?

Question

Accepted Answer

Counter flow with process stream on shell side. Counter flow is generally the best arrangement for heat exchangers to maximize heat transfer. Placing the process stream on the shell side is a common and effective configuration.
