Shell and Tube Heat Exchanger Design For Producing Methylaniline
This study aims to design a heat exchanger. HE or Heat Exchanger is the most important tool in the process of completing various energy cycles. The heat exchanger is designed with a two-pass shell and tube type to produce methylaniline. This research is studied to obtain some of the main dimensions of the equipment, such as the heat insulation surface area (A) which depends on other parameters, namely thermal load (Q), overall heat insulation coefficient (U) and logarithmic average temperature difference (∆Tlm). The heat exchanger design calculation method is done manually using the Microsoft Excel application. The results of manual heat exchanger design calculations result in a shell length of 16 ft, an inner pipe diameter of 1.12 in, a shell diameter of 17.25 in, and a thickness of 0.65 in. The effectiveness value obtained is 11.62% with an impurity factor of 0.0061. Based on the results of these calculations, although the effectiveness value obtained is still relatively small, the two-pass shell and tube heat exchanger design still meets the criteria or requirements of the TEMA standard.
