Biodiesel fuel purification in a continuous centrifugal contactor separator: An environmental-friendly approach

Wet washing is the most common method for biodiesel purification, but higher water consumption, longer purification time, and high expenses bring limitations on use of this process. One suitable methods to remove such new techniques purification. In study, was evaluated in a novel continuous centrifugal contactor separator (CCCS) at 0.5:1, 1:1, 1.5:1 (V/V%)water ratio; 10 Hz, 20 30 Hz device working frequency; 25 °C, 40 55 °C temperatures. A mathematical model wet-washing process energy consumption CCCS using response surface proposed. 0.8:1 (V/V%) ratio, frequency, 35 temperature were found be optimal conditions experiment. At point, yield amount reported 96% 17 kJ, respectively. The results showed that compared traditional wet method, cost-effective consumes more than 75% less water.
