Crude glycerin (also spelled glycerine or glycerol) is a by-product formed during the production of biodiesel, soap, and fatty acid processing. It is a thick, syrupy liquid with a pale yellow to brown color and has a lower purity compared to refined glycerin.
Composition:
Crude glycerin typically contains:
Glycerol (40â??80%) â?? the main component, though at a lower concentration than in refined glycerin
Water (up to 20%)
Methanol (if from biodiesel)
Soap, salts, free fatty acids, and traces of catalysts (e.g., sodium or potassium hydroxide)
Other organic matter or impurities depending on the feedstock and process
Uses of Crude Glycerin:
Feedstock for Refining.
Crude glycerin is often refined and purified to produce pharmaceutical- or food-grade glycerin, which is used in cosmetics, foods, and medicines.
Animal Feed (after purification).
Can be blended into livestock feed as an energy source, but only after removal of toxic methanol residues.
Biogas Production.
Used as a co-substrate in anaerobic digesters, boosting methane production in biogas plants.
Industrial Applications.
Used in the manufacturing of paints, resins, antifreeze, adhesives, and plasticizers.
Combustion and Fuel.
Sometimes used as a low-grade fuel or fuel additive in industrial burners and boilers.
Chemical Intermediate.
Serves as a base chemical for producing propylene glycol, epichlorohydrin, and other derivatives.
Products Description
Glycerol is a colorless, viscous, hygroscopic, sweet-tasting trihydric alcohol. It is also called glycerin or glycerine, with the term glycerol being preferred as the pure chemical form and the term glycerin(e) being primarily used when the compound is used commercially in various grades.
Application
1) In medicine, it is used to making various preparations, solvent, hygroscopic agent, antifreeze and sweeteners, preparation for external use ointment or suppository, with glycerol nitroglycerin used for explosive materials.
2) In the coatings industry, it is used for making all kinds of alkyd resin and polyester resin, epoxy resin and glycidyl ether.
3) In textile and printing industry, it is used for preparing wetting agent hygroscopic agent, fabric anti-creasing shrink proof treatment agent, dispersant and penetrating agent.
4) In the food industry , it is used as sweetener, tobacco hygroscopic agent and solvent.
5) In addition, in the paper, cosmetics, leather, photography, printing, metal processing rubber and other industries widely application.
Glycerol (also called glycerine or glycerin) is a simple polyol compound. It is a colorless, odorless, viscous liquid that is sweet-tasting and non-toxic. The glycerol backbone is found in all lipids known as triglycerides. It is widely used in the food industry as a sweetener and humectant. Glycerol has three hydroxyl groups that are responsible for its solubility in water and its hygroscopic nature.
