Used 50 TPD Glycerin Plant commissioned in 2002 and shut down in 2008. This plant is designed to encompass crude distillation and glycerin bleaching, producing USP pharma grade glycerin. The plant consists of a pre-dryer, a structured packing distillation column, and a continuous bleaching unit. The process incorporates two post-addition stills for residue recovery, and can be modified to be capable of running "all vegetable" based biodiesel crude once a precut column is installed to remove methanol. The glycerin produced will be in accordance with pharmaceutical glycerin specifications, with a concentration of 99.8% glycerin minimum.
