Abstract

Oil recovery may be increased by lowering interfacial tension between oil and water due to surfactant injection. Bagasse is one of the organic materials which has a fairly high lignin content, where lignin is the basic substance of making Natrium Lignosulfonate (NaLS) Surfactants. The research was divided into three sections. The first was experiment to produce lignin from bagasse. In this experiment 100 gram of bagasse with size of 60 mesh or 80 mesh extracted by benzene + ethanol (2:1) and then 20%, 50%, or 75% NaOH was added to activate lignin. The maximum amount of lignin produced was 24.88%. The second experiment was to produce NaLS surfactant from obtained lignin. FTIR equipment was used to verify the NaLS surfactant yielded using the method. The maximum amount of NaLS surfactant produced was 20.264% of bagasse mass. After that NaLS surfactant obtained from the previous process was used in chemical flooding experiment. In the experiments, the surfactant concentration in the solution was varied at 0.05%, 0.10%, 0.15%, and 1.00%. While temperature was set at 30°C, 40°C, 60°C, 70°C, or 80°C. The optimum condition happened when a solution with surfactant concentration of 1% was injected at 60°C. The recovery factor of oil using the condition was 0.47.

Abstract

Zeolite as a catalyst can increase its activity by carrying out physical and chemical activation processes. Physical activation can be activated by reducing the size of the zeolite through grinding and sieving methods, from the physical activation process it can increase the surface area of the zeolite. In this study, zeolite was chemically activated by acid activation method by immersing natural zeolite with HCl and HF. The oxide compound in the activated zeolite was characterized using XRF. The activated zeolite was used to reduce the free fatty acid levels with variations in the addition of 7 to 10 grams of zeolite. The content of free fatty acids is then compared with the quality requirements of cooking oil according to SNI 01-3741-2013. The results of the research conducted showed that there were differences in the content of oxide compounds in zeolite before and before activation with differences in SiO2 content, namely 69.4% before activation and an increase of 82.1% after activation. The results of the state test including physical properties, odor, and taste tests of used cooking oil that have been purified indicate that used cooking oil that has been purified meets the quality requirements of cooking oil based on SNI 01-3741-2013. Used cooking oil that has been purified has a normal taste, does not smell. rancid and yellow. The content of free fatty acids meets the requirements of SNI 01-3741-2013 for all variations of the addition of zeolite with the highest decreasing value obtained at the addition of 10 g of zeolite with a free fatty acid content value of 0.22%.
