Mass Transfer CFD Modeling of Biodiesel Purification Using Deep Eutectic Solvents in a Microseparator
Biodiesel is an alternative fuel, similar to classic fossil fuels that can be used in diesel engines. It is a mixture of alkyl esters of fatty acids that can be produced from vegetable oil, micro algal oil or animal fats. Biodiesel production is mostly achieved through transesterification, using short-chain alcohols (typically methanol or ethanol). This reaction also produces glycerol, which along with unreacted alcohol and oil, has to be removed from the product before it can be used in commercial application. There are several approaches that can be used for biodiesel purification (sedimentation, decantation, water washing, filtration etc.) but all of them are usually characterized as inefficient, non- ecological, expensive, energy consuming etc. In order to resolve some of this disadvantages microseparators coupled with deep eutectic solvents (DESs) were proposed as solution. Microseparators have been widely used to improve the mass and heat transfer processes between two phases due to the high surface-to volume ratio, higher heat and mass transfer rates and short diffusion distance. To achieve the maximum productivity of the biodiesel purification process in a microseparator it is necessary to take into account nature of the components and the operational conditions, such as temperature, volumetric flow rate, dimensions of the used microchannel. All mentioned parameters significantly influence the flow pattern formation. In this work computational fluid dynamics (CFD) analysis was carried out to illustrate and visualize the interactions between two existing phases in separation systems.
