Abstract

Microreactors are widely applied, especially in heterogeneous reactions limited by mass and or heat transfer.In many chemical reactions, microreactors perform well in obtaining a high yield, selectivity, and conversionup to 100%, which is not easy to realize using conventional reactors. The excellent performance results fromthe high stability of the two-phase flow, namely slug flow pattern. A comprehensive study of slug flowcharacteristics inside the microchannel is needed to have a good performance. For that reason, the presentwork focused on the study of slug flow characteristics and its stability by using a circular microtube with 0.5,0.8, and 1 mm inside diameter, and the 2-liquid phase consisted of aquades-kerosene and aquades-ethylacetate with aquades as a dispersed phase and kerosene or ethyl acetate as a continuous phase. These liquids represent two liquid mixtures with different physical and chemical properties, significantly influencing the formation of 2-phase flow patterns in a microtube. Variables used in the experiment were temperature,channel diameter, and volumetric flow rate. Observation results show that the slug flow pattern was found atthe ratio of the volumetric flow rate of disperse phase to the continuous phase (Qd/Qc) is 1; 1.4; 1.8; and 2.2.The slug flow formed at a flow rate of 70 ml/h for both the dispersed phase and the continuous phase (Qd/Qc=1) had the most stable droplet length and the distance of consecutive droplets. Increasing Qd/Qc ratio increases the droplet length formed, and in the range of discharge used, the change in inside tube diameter from 0.5 to 1 mm does not change the flow pattern model, but it affects the slug length.
