Glycerin is an important light chemical industry raw material, it is wide used in coating, explosive, plastic, toothpaste, cosmetic, food, chemical industry, medicine and so on. With the development of bio-diesel, the output of glycerin is rising rapidly. At the same time, the output of glycerin derivative is rising rapidly. It is a trend to build large scale fine factory of glycerin solely to process ester exchange/ saponify crude glycerin. For the different raw material of glycerin, we developed the purification techniques of glycerin basing on animal /vegetable oil and exchange/ saponify crude glycerin. Flowchart: The glycerin recovery plant developed by us has many advantages, such as: High purity up to medical grade requirement. Energy using integrated, low energy input. Adopting fixed bed destain avoiding environment secondary pollution. Adopting especial thin film evaporator to distill resdue secondarily to ensure the contents of glycerin in resdue is low. Adopting especial technology to discharge resdue, not easy to jam, running continuely.
