Abstract

Heat Exchanger is a device used to transfer heat between fluids to get the temperature operating conditions as needed. This research was conducted to obtain Heat Exchanger design calculations to solve problems and adjust the needs of PT X. The design of the Heat Exchanger is obtained by the Double Pipe Heat Exchanger type with a heat transfer area of 7.37 ft2. The hot fluid, Condensate Steam, will fill the inner pipe while the cold fluid in the form of refrigerant water will fill the annulus pipe. Superheated steam has a temperature higher than its boiling point at the same pressure. Steam condensate is steam that has cooled and condensed back into water after being used to do work or after losing heat.The length and number of hairpin heat exchangers are 10 ft and 1 hairpin. The height of the heat exchanger is 30cm. The designed heat exchanger uses turbulence flow type to optimize and streamline heat transfer. The performance and capability of the heat exchanger obtained Overall Dirty Coeficient Heat Transfer (Ud) 250 Btu/hr ft2 oF, Overall Clean Coeficient Heat Transfer (Uc) 558.027 Btu/hr ft2 oF, Fouling Factor (Rd) 0.002. The pressure drop values for both annulus and innerpipe are 0.99 psi and 2.321 psi, which do not exceed the safe limit. The friction values obtained on the innerpipe and annulus are 0.006 and 0.0105.
