SUMMARY LOOPING SYSTEM APPLICATION IN UTILIZING RESIDUAL CO2 FROM CONVERSION CO2 TO METHANOL AND METHANOL PURIFICATION THROUGH CONTINUOUS DISTILATION Yollanda Nurcholifah: Supervised by Dr. Dedi Rohendi, M.T and Dra. Julinar, M.Si Department of Chemistry, Faculty of Mathematics and Natural Science, Sriwijaya University x + 54 pages, 3 tables, 11 images, 13 appendices CO2 conversion can produce compounds that can be used as raw materials and fuels, such as methanol. Not all of the supplied CO2 gas can be converted to methanol, but there is residual CO2 that is not converted. The Looping system method is used to utilize unconverted residual CO2 so that it can be reused in the system to produce methanol. CO2 gas is supplied by freeing gas flow to MFC (Mass Flow Controller) 1, then flowed to MFC 2 with a flow rate of 480 mL/minute at a voltage of 1.8 V. The residual CO2 flows back to MFC 3 with the help of a peristaltic pump. The residual CO2 returned to the system will help reduce the CO2 supply. It is known from MFC 1 which shows a decrease in flow rate. The methanol product produced on the cathode side was purified by continuous distillation method and concentration of methanol was measured using the Methanol Analyser Analox AM5. The operation of CO2 conversion with a looping system on a multi-stack electrolyzer is carried out in parallel circuits using varying operating times, namely for 2, 4, 6, and 8 hours. The percentage value of the converted CO2 efficiency and the CO2 flow rate from the inlet tube did not change significantly at various operating times with the highest converted CO2 efficiency percentage values being at 2 and 6 hours of operation, amounting to 83.333% and the lowest MFC1 input CO2 flow rate at 4 hours of operation hour by 434 mL/minute. Currents that tend to be stable are at 2 hours of operating time, starting with an electric current of 0.32 A and ending at a current of 0.33 A. The highest percentage of methanol from the conversion before distillation and after distillation is at 2 hours of operation, that is, respectively percentages of 7.83 and 63.850 % (w/v).
