Abstract

The production of biodiesel involves mixing organic oil (palm oil) and short chain alcohol (methanol) which are not miscible. The interfacial area between the two phases is believed to strongly affect the reaction rate and therefore, there is an interest in developing a suitable method to measure the methanol droplet size distribution in palm oil. Development of a suitable measurement technique would contribute to imaging measurement and analysis techniques. However, the desired concentration of methanol (20% volume fraction) as well as the inherent smooth interface in liquid-liquid systems presents a further challenge in the measurements. The measurement system consists of a modified borescope, stroboscope and a high speed digital camera. This presentation discusses about capturing the drop size distribution of the methanol-palm oil system with appropriate calibration and testing.
