Used 50 TPD Glycerin Plant built in 1970. 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.
