Abstract
The objective of this research was to study the pressure drop and purities of methyl ester when the fluid flowing through Kenics static mixer (KSM) and Lightnin static mixer (LSM) which made by the 3D printer. The length-to-diameter ratios (L/D) of mixing elements in the tube were studied and compared with the plug flow reactor (PFR). The continuous biodiesel productions from refined palm oil (RPO) using 3D-printed static mixer reactors were carried out to assessed the purity of methyl ester with the condition was 23.81 vol.% methanol and 11.8 g.l-1 KOH at 25 l.h-1 flow rate and 50oC initial temperature of RPO. The results showed that the both types of static mixer with 1.0 of L/D ratio required a highest pumping power requirement to overcome the pressure drop. In addition, LSM type more required the pumping power than the KSM type and PFR. Finally, the static mixer reactors were used to evaluate the purity of methyl ester when the reactant of mixtures flowed through the in-line continuous flow reactor. The highest methyl ester purity of 45.04 wt.% obtained when LSM static mixer type was used followed by KSM and PFR, respectively.
