Design and Technical Testing for Crude Biodiesel Reactor Using Dry Methods: Comparison of Energy Analysis

The objectives of this study were to design biodiesel dry washing reactor and to analyze energy consumption between this method and water washing method. The reactor was disigned continously. The reactor exhibited washing capacity of 0.56 kg/minute, energy consumption of 315 kJ/kg, while energy consumption of water washing was1361 kJ/kg. Biodiesel quality produced from the reactor meets the biodiesel standards: methyl ester was 98.65%, total glycerol was 0.24%, acid value was 0.41 mg NaOH/g oil, moisture content was 0.41%, density was 0.86 kg/m3, and viscosity was 6.00 cSt. The energy ratio between dry and water washing methods was 0.23.
