Glycerine Recovery Glycerine Water Treatment & Evaporation

Glycerine is a ubiquitous substance that is widely found in nature and has a broad range of uses ranging from Cosmetics to Food Products.

Mectech has long experience in the Oils & Fats and Oleo—Chemical industry sectors which has long been associated with the production of Glycerol as a by-product. Plants executed by Mectech produce Glycerol by the following means — the Transesterification of Methyl Esters, from Fats Splitting, and by Saponification which is used to produce soap.

The Glycerine / Sweet Water purification and evaporation allows maximum recovery and pre-treatment before evaporation to produce Crude Glycerine. The pre-treated sweet water is concentrated in Triple Effect or Quadruple Effect Evaporation systems under vacuum. The use of multiple effects reduces the requirement of steam.


  • Energy-saving devices attached to Splitter reduce the size of the Glycerine/Sweet Water purification and evaporation plants, thereby, reducing the overall consumption of utilities for the Sweet Water Pre-Treatment and Evaporation section.
  • Multiple effect evaporation system is designed for Glycerine Evaporation which makes efficient use of Steam required for Evaporation.
  • The Condensate water from the System is collected and Recycled for Splitting.
  • The extremely efficient heating candles strip the last possible traces of Glycerine from the residue to maximum recovery.
