Hydrodynamic, Mass Transfer and RTD Studies of Fluid Flow in a Spiral Microreactor
In this article, the spiral microreactor made of copper tube with U-junction, mixing region, was used to study the reactor performance on sodium hydroxide-n-butyl acetate system. The internal diameter of microreactor is 1.5 mm and length is 2 m. The performance of spiral microreactor was studied considering hydrodynamic flow, mass transfer characteristics, RTD and computational analysis of fluid flow using n-butyl acetate and sodium hydroxide system. Pressure drop was estimated in spiral geometry using dean number and compared with simulation results for laminar flow. The volumetric mass transfer coefficient obtained was in the range of 0.02–0.37 s−1. The dispersion number calculated from the RTD study was equal to 0.0526 indicating the plug flow conditions.
