The goal of the case study is to determine the steam flow rate and saturation temperature that will allow a solution of water and ammonia nitrate (ANSOL) to be heated in a shell and helical coil tube heat exchanger during a time period without the ANSOL solution crystallising. The solution's desired production per batch is 5750 kg in 80 minutes. The heat transfer rate and temperature profiles that satisfy the imposed criterion within a given degree of safety and at the lowest possible cost in steam generation are determined using the concepts of efficiency and effectiveness. The Reynolds number, Nusselt number, and global heat transfer coefficient for the shell and helical coil tube heat exchanger are intermediate quantities required to achieve the goal. The water is heated for a predetermined amount of time before the ammonium nitrate is introduced to a given flow at a predetermined mass flow rate.
