In the production of biodiesel fuel, glycerin is one of the by-products after the mixing and reaction process. The remaining concentration of glycerin must be know so that it can be removed, typically by a centrifugal process. High levels of glycerin are undesirable in the operation of diesel engines as they will cause injector deposits and may adversely affect cold weather operation and cause filter clogging. The Spectro FTIR and FluidScan are two analytical instruments that can be used to monitor the total concentration of glycerin in biodiesel prior to its removal process, and afterwards to determine the efficiency of the process. These instruments can also be applied as quality control methods to verify that delivered biodiesel blend ratio and glycerin content are as specified.
