This final project presented a shell and tube heat exchanger design for compressor aftercooler. This design was done because the performance of aftercooler is not matching with company need, i.e. the fouling rate is too high, and both outlet temperature and outlet humidity are higher than required conditions. The working fluid that was used in this design is compressed air in tube side and cooling water in shell side. Heat transfer analysis used Kern method and Delaware method. The calculation was applied to three chosen design alternative. The alternative design which was recommended to the company is the most inexpensive one. The detailed design on heat exchanger components was done based on Standards of Tubular Exchanger Manufacturers Association (TEMA). The heat exchanger type that was chosen is BEW type single pass shell and tube. According to the chosen heat exchanger geometry, the fluid flow in shell side was analyzed by CFD software of FLUENT to find flow pattern and properties of this fluid. Delaware method gave more accurate result compared to Kern method. This final project is hoped can be an alternative to substitute the existing heat exchanger.
