Abstract
The present invention provides glycerin refining process includes the steps of drying coarse glycerin product with content over 80 %, vacuum distilling to purify at the vacuum degree below 4 KPa, distilling the residue, and deodorizing and decolorizing with active carbon. The refined glycerin has purity up to 99.5 % and is suitable for medical use.
Description
Technical field
The present invention relates to a kind of biodiesel technology, especially the concise technology of glycerine.
Background technology
Present glycerine refinement technique has: contain quantitative powdery serum adding biological enzyme formulation for 20-30% and liquefy, saccharification again, add nutritive substance, adopt good oxidized form to produce bacterium pearl Candida SpWL-2002-5, in corresponding fermentor tank, carry out aerobic fermentation, adopt centrifugal or filter press removal thalline, carry out vacuum concentration then, add carrier 5-30% and carry out vacuum distilling, adopt dry method or wet method to wash pot, pass through deodorization decoloring then, can obtain the serial glycerol product of 80-98%.In addition, domestic also have the batch distillation of employing technology, but these mode rate ratios are lower, and purity is medicinal inadequately.
Summary of the invention
The invention provides a kind of concise technology of glycerine of high density.
For achieving the above object, technical scheme of the present invention is:
A kind of method for refining of glycerine comprises by raw glycerine and carries out refining, it is characterized in that adopting content to surpass 80% the vacuum distilling purification that raw glycerine is at first dry and 4Kpa is following, carries out the residue distillation again, carries out deodorizing with activated carbon then and gets final product with decolouring.
The glycerine of Ti Chuning possesses good purity like this, is fit to medicine and uses.
Embodiment
In concrete the enforcement,, can be soda soap with micro-lipid acid contained in the raw glycerine or inmature saponification, prevent that it from entering distillment with sodium hydroxide for guaranteeing the purity of glycerine; Simultaneously, be the quality product of control glycerine, the temperature and the distillatory vacuum tightness of necessary strict controlled chilling water.
Whole process is: wastewater treatment, concentrate, vacuum distilling, deodorization and the decolouring of raw glycerine.
Claims (2)
1. the method for refining of a glycerine comprises by raw glycerine and carries out refining, it is characterized in that adopting content to surpass 80% the vacuum distilling purification that raw glycerine is at first dry and 4Kpa is following, carries out the residue distillation again, carries out deodorizing with activated carbon then and gets final product with decolouring.
2. according to claim 1, it is characterized in that sodium hydroxide is soda soap with micro-lipid acid contained in the raw glycerine or inmature saponification.
