9. Sub Unit of Dekanter
This sub unit is used to separate methyl ester from water, the remaining methanol, catalyst, and glycerol Figure 3.25. The input on line number 22 is :
methyl ester, FFA, triglyceride, methanol, KOH catalyst, glycerol, water, and dirt. While the output on line number 23 is : Water, Methanol, KOH catalyst, glycerol,
and dirt. The output on line number 24 is: methyl esters, FFA, triglycerides, methanol, KOH catalyst, glycerol, and water.
