Biodiesel Production

3-MCPDE = 3-monochloropropanediol esters GE= Glycidyl esters

How to reduce 3-MCPDE and GE?

3-MCPDE Mitigation GE Mitigation

• CPO washing • Use Neutral Clay • Low Temperature

Deodorization

• Post Refining • Low Temperature

Deodorization • GE Stripping

Chloride Content (ppm) Chloride Reduction (%)

CPO Washed CPO

0.48 - 2.92 (Low Cl Content)

0.13 - 1.27 56.5 - 72.9

3.12 - 6.33 (Medium Cl Content)

0.57 - 1.23 80.5 - 81.7

10.18 - 18.39 (High Cl Content )

0.25 - 0.89 95.1 - 97.5

*Results Analyzed by MPOB Number of samples collected: 24

- Washing efficiency is higher when the Cl content in CPO is high. - However, not all Cl can be washed out by water. - High Cl content can be reduced to <2ppm by washing process

Advantages – Lipochem CPO Washing

1. Complete solution with PLC Control System

2. Able to take in CPO with higher phosphorous content or even palm fibre oil with built-in acid degumming facilities.

3. Easily integrated in Palm Oil Mills and also Refineries

4. Proven system for chloride removal
