How is glycerol purified?

Answers

Answered by badal7

Glycerin naturally occurs during the biodiesel production process and is specifically produced in the transesterification process. Theglycerin produced at this stage is crude glycerin and is about 80% pure still containing contaminants like soap, methanol and water.

Cumber: Thank you so much! But, I should have made it clear which distillation process is conducted to purify glycerol. Could you answer again? Thank you again. :)

badal7: Glycerol purification process. ... Purification and refinery Vacuum Distillation Ion Exchange .... dehydration Thus, puriﬁcation has to be done in vacuum

The increase in biodiesel production over the past ten years has resulted in substantial increases in glycerin production throughout the world. Because of the large supply of crude glycerin in particular, biodiesel production facilities are looking for alternative ways to purify this glycerin to maximize their profits.

SRS International Corporation has designed a high-purity glycerin purification system giving biodiesel plants the ability to create additional profits through purification of their crude glycerin. Glycerin’s value is based on its purity range so the purer the glycerin, the higher the market value. SRS International’s system can produce high-purity glycerin in high yield, while maximizing energy efficiency. The system can take crude glycerin with an approximate purity rating of 80% to a technical grade glycerin of >97%.
