The Glycerine Refining plant has a special design to process Crude Glycerine from biodiesel, with high content of MONG, Soap and Methanol.

Step 1 – Methanol Evaporation Unit, where most of methanol is removed and sent to DUAL USE COLUMN for rectification. Crude Glycerine from this unit is sent to Step 2.

Step 2 – Chemical Pretreatment Unit to remove most of Soap and MONG from Crude Glycerine.

Step 3 – TECHNOILOGY new design DUAL USE COLUMN which is fed with both crude methanol recovered by Methanol Evaporation Unit and Crude Glycerine coming from Chemical Pretreatment Unit.

The following streams are obtained:

• Methanol at 99.9 % from the column top.
• Concentrated Crude Glycerine from the column bottom which is sent to Step 4.
• Process Water from the middle of the column, which is recovered to the process units.

Step 4 – Glycerine Distillation and Refining Unit to produce Pharma Grade Glycerine (fulfilling the international Pharma Grade specifications) from Crude Glycerine.

All key equipment has been manufactured in our Italian workshop.
