6. Sub Unit of Transesterification 2
This sub unit is used to react triglyceride with methanol to produce methyl ester biodiesel using KOH catalyst Figure 3.22.
Figure 3.22 Sub unit of transesterification 2 The input on line number 16 is: methyl ester, FFA, triglyceride, methanol,
KOH catalyst, glycerol, water and dirt. The input on line number 17 is: methanol, KOH catalyst, and water. While the output on line number 18 is: methyl ester,
FFA, triglyceride, methanol, KOH catalyst, glycerol, water and dirt.
7. Sub Unit of Centrifuge 3
This sub unit is used to separate methyl ester from glycerol, water, dirt and catalyst Figure 3.23.
Figure 3.23 Sub unit of centrifuge 3 The input on line number 18 is: methyl ester, FFA, triglyceride, methanol,
KOH catalyst, glycerol, water, and dirt. While the output on line number 19 is: methanol, KOH catalyst, and water; the output on line number 20 is: methyl ester,
FFA, triglyceride, methanol, KOH catalyst, glycerol, water and dirt.
8. Sub Unit of Washing Tank
This sub unit is used to remove residual methanol and catalyst dissolved in methyl ester Figure 3.24. The input on line number 20 is: methyl ester, FFA,
