Waste glycerol purification involves pre-purifying glycerine impurity content and neutralizing with acid under stirring
NOVELTY – Waste glycerol purification involves pre-purifying glycerine impurity content at 35-55 wt% and neutralizing with acid under stirring to adjust pH 7.0. The obtained glycerine is filtered in vacuum, in which an anti-polymerizing salt is added. USE – Method for purifying waste glycerol. ADVANTAGE – The method purifies the glycerol in cost-effective and eco-friendly and manner without generating pollutant byproducts and wastewater. DESCRIPTION OF DRAWING(S) – The drawing shows a flowchart for pre-purification and purification of residual glycerin. (Drawing includes non-English language text).
