Abstract
The purpose of this research is to find out the performance of heat exchanger based on the limitations such as follow, type of heat exchanger that is analyzed in this research is shell and tube heat exchanger, process fluid and cold fluid work in counter flow. The calculated performance is the rate of heat transfer, the log mean temperature difference (∆TLMTD), the overall heat transfer coefficient, the fouling factor and the effectiveness method of NTU. This research was done in Semen Kupang II Industry. The method used in this research is descriptive analysis, according to the information of the data that were collected in the field of research. Based on the result of the analitical calculation, it is known that the decreasing of the rate of the heat transfer is about 967.741 Watt – 760.172 Watt, with the increasing of fouling factor is about 0.054 m2.oC/W – 0.194 m2.oC/W. The result of effectiveness of the heat exchanger is about 0.28 – 0.29, otherwise based on the relation of NTU and Cmin/Cmax results effectiveness on value of 0.64 – 0.45.
