ABSTRACT

The aim of this project was to construct shell and tube heat exchanger with fixed boundless. A heat exchanger that would cool 5 x 5 x 10 – 3 kg/s of steam at a calculated heat load of 152 – 395/S was fabricated. The steam is to reach the heat exchanger from a distillation column at a temperature of 300k. The specification of  the layout as well as the detailed mechanical design were assumed and also calculated.

It is established that a horizontal heat exchanger with cold water at the shall side and the treated steam at the tube side is adequate for this operation, with the aim of cooling the steam from the distillation column.

        The available area obtained from calculation is 1.0m2 and also the overall heat transfer coefficient obtained is 4.10W/M2k. it is also seen that the heat exchanger is satisfactory and consists of five copper tubes of inside diameter 90mm and 5920mm length. The shell inside diameter 810mm and 5.770mm length. The tube and shell heat exchanger has a total length of 5820mm.

The material of construction for the shell side is stainless steel while copper tubes were used for the tubes inside. 

The total cost of the heat exchanger was N12,000.
