Abstract

Heat exchange design for ethanol vapors control, used low temperature fluid heat exchanges with high temperature ethanol vapors until the vapors phase change from gas to liquid and controls the amount of volatile organic compounds released. The simulation design, determine water temperature 25, 20, 15, 10, 5 °C and ethanol temperature 41 °C. The simulation materials used for heat exchange are the copper, steel and stainless. The result shown heat exchanger is a copper, which reduce the ethanol temperature to the maximum at 17.36 °C and water temperature at 5 °C. The simulation model used water temperature at 5 °C and velocity 0.01, 0.02, 0.03, 0.04, 0.05 m/s. The velocity result at 0.05 m/s be able to use the most of heat exchangers, which ethanol temperature was 12.34 °C and the total heat transfer coefficient was 877.3 w/m2.°C. The simulation results from the computer programming could be used to heat exchange of the ethanol vapors to ethanol liquid. The theoretical and hypothesis for research, its can be used as information in the design and guidance to those who are interested in further development.
