Understanding Crude Sources

Different production methods yield crude glycerin with unique characteristics. Our plants are engineered to handle them all.

Transesterification

From Biodiesel Production. Contains methanol & salts.

Purity 70-85%

Saponification

From Soap Manufacturing. High salt content challenge.

Purity 15-25%

Hydrolysis

From Fat Splitting. Requires precise water removal.

Purity 95-98%

The 5-Stage Purification Core

A vertical journey from crude to crystal clear pharmaceutical grade.

01

Deaeration

Removing dissolved gases and volatiles under vacuum to prevent oxidation and ensure smooth distillation.

Vacuum Pressure: < 50 mbar
Temp: 100-110°C
Removes: Air, Methanol, Water traces

02

Primary Distillation

Separating ash, mong and other impurities. The first major leap in purity concentration.

Temp: 140-150°C
Efficiency: 90% glycerin evaporation on purity basis
Tech: Forced Circulation Through Reboiler

03

Secondary Distillation

Advanced salt separation and removal of intermediate boiling impurities for high-purity recovery.

Purity Target: 98%
Separation: Salts & Pitch
Tech: Forced Circulation Through Reboiler

04

Deodorization

Stripping residual odors and color bodies via controlled steam injection under high vacuum.

Vacuum: < 5 mbar
Result: Odorless liquid
Process: Steam Stripping

05

Bleaching

Final polishing through activated carbon filtration to achieve pharmaceutical-grade clarity and color.

Final Purity: >99.5%
Color: APHA < 10
Standard: USP/BP/EP
