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

3.12 - 6.33 (Medium Cl Content)
0.57 - 1.23 80.5 - 81.7

*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
