Technical Document

Brief Overview

Crude glycerine, characterized by its viscous consistency, innate sweetness, and a chromatic spectrum ranging from light yellow to dark brown, represents the unrefined manifestation of glycerine. It is sourced from both natural and chemical feedstocks, primarily existing in vegetable oils and fats in the form of triglycerides, alongside its presence in animal fats. This byproduct is derived from biodiesel manufacturing plants and oleochemical industries. The shift towards renewable energy sources has induced a notable surge in biodiesel production, consequently amplifying the generation of crude glycerine. The specifications for crude glycerine typically stipulate an 80% glycerine content, with the remaining composition comprising impurities such as methanol, soap, catalyst, salts, non-glycerine organic matter, and water. This intricate interplay of factors underscores the intricate nexus between biodiesel production, renewable energy initiatives, and the resultant crude glycerine byproduct.

Manufacturing Process

Degumming

Degumming is a crucial step in refining vegetable oil, involving precise removal of phosphatides through centrifugation. Water is added to precipitate dissolved phosphatides, which become heavier masses due to absorbed water. Centrifugation then separates these phosphatides, effectively eliminating impurities and refining vegetable oil, extending its storage life.

Deacidification

Deacidification follows, using solvent extraction on vegetable oils. The initial step agitates vegetable oil in methanol, causing free fatty acids to dissolve, reducing their concentration. Removal of these acids is crucial for extending storage time and facilitating further refining.

Transeferication/Saponification

The deacidified oil undergoes transesterification/saponification, breaking triglyceride chains into glycerol/glycerine and fatty acids. This step, conducted under high temperature and pressure with water, makes glycerine accessible for extraction, setting the stage for additional refinement.
