Abstract
A heat exchanger, especially a shell-and-tube type, is a heat transfer mechanical device that is widely used in various industrial fields, such as oil, petrochemical, energy and so on. The function of a heat exchanger is to transfer heat from one fluid with a higher temperature to another fluid with a lower temperature. In this research, shell-and-tube heat exchanger was chosen because this type of heat exchanger is the most widely used in the industry in general and in the oil and gas industry in particular. This research was conducted to determine the performance of shell and tube type heat exchangers in terms of thermal and hydraulic. Data acquisition is done by observing in the field. So that the data processing and calculation results are obtained as follows: Shell side pressure drop of 19.73 psi has exceeded the minimum requirement of 10 psi, so it is time for cleaning, tube side pressure drop of 1 , 47 psi is still below the minimum requirement of 10 Psi, the effectiveness of the operation is 57.47% below the design value of 68.73%, and the simulation using excel-solver as follows in the gross condition can be increased to 79.93% effectiveness with a shell side pressure drop (6.2 psi), tube side pressure (9.98 psi) with shell side velocity (0.98 ft / s) and tube side (9.5 ft / s)
