These heat exchangers are employed when a process required large quantities of fluid to be heated or cooled. Due to their compact design, these heat exchangers contain a large amount of heat transfer area and also provide a high degree of heat transfer efficiency. Over the years, many different types of shell and tube heat exchangers, have been designed to meet various process requirements. In the industry today, heat exchangers are most often designed with the aid of software program. Given the required specifications for a heat exchanger, these simulators perform the appropriate calculations. In this project, we try to use a computer approach in designing a shell and tube heat exchanger. We started by designing an algorithm that covers the chemical engineering design such as the estimation of fluid and material properties, film and overall heat transfer coefficient, exchanger surface, tube layout and pressure drop. It also covers the mechanical engineering design of calculating the shell and channel thickness, shell cover thickness, channel cover thickness e.t.c. These algorithm was translated unto a program using a micro soft visual basic 6.0, an object oriented computer programming language. With this program, the computer takes over and automatically per for all the complex computations with little or no human effort and gives an output which is the design information needed.

CONSTRUCTION OF HEAT EXCHANGER FABRICATION OF A TUBE AND SHELL HEAT EXCHANGER SYSTEM ABSTRACT There are two methods of constructing heat exchangers: Plate type. Parallel flow-the hot fluid and the coolant flow in the same direction. Counter flow:- The hot fluid and the coolant flow in opposite direction. Cross flow: The hot fluid and the coolant...

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... Continue Reading

ABSTRACT According to the modern or dynamical Theory of heat: Heat a form of energy. The molecules of a substance are in parallel motion. The mean Kinetic energy per molecules of the substance is proportional to its absolute temperature. In description of heat, a molecule may consist of one or two or many atom depending upon the nature of the gas.... Continue Reading
