Measuring Mass Transfer on Biodiesel Process by Means of Impedance Measurement

Abstract:

Transesterification is commonly used to produce biodiesel from methylester. In order to control the conversion process is useful to employ process monitoring, in particular monitoring of the mass transfer processes that limits the initial rates of transesterification. Monitoring of these initial stages of the reaction may allow for process optimization. Many methods have been identified to monitor reaction progress. This paper proposes a method to monitor the initial stages of the biodiesel production process using impedance measurement. The impedance measurements presented show the expected sigmoid curves that are associated with mass transfer (mixing) processes taking place during the early stages of the transesterification process.
