“…In general, the advantages of the dry washing method include shortening the biodiesel refining process time, reducing the amount of water used, reducing waste generation, and lower operating costs. In addition, the energy consumption of this method is 23% smaller than the method of washing with water (Alamsyah and Loebis, 2014).…”

The process of biodiesel purification is an important step in getting biodiesel products that meet specifications as a substitute for fossil-based fuels. Dry washing method has been developed to achieve an effective puriﬁcation strategy in order to produce high-quality biodiesel. Bentonite can be used as dry washing agent because it has a good adsorbing properties as well as a large pore and surface area therefore can attract polar substances such as glycerol and methanol. The purpose of this research is to know the capability of activated bentonite as dry washing agent for purification of biodiesel produced from waste cooking oil. The activation process of bentonite was carried out using sulfuric acid with concentration 1.5 M. Characterization of the bentonite was conducted using X-Ray Diffraction (XRD) for minerals content and Brunauer–Emmett–Teller (BET) method for surface area. Bentonite was used as dry washing agent for biodiesel purification by varying washing time (10, 20, 30, 40 and 50 minutes) and adsorbent amount (1, 2, 3, 4 and 5%). The experimental results showed that purification of biodiesel by dry washing using activated bentonite resulted in a better yield and quality than wet washing and dry washing using non-activated bentonite, except the acid number. The best operation condition resulted from this research is at 10 minutes washing time and 1% adsorbent with yield of 94.1%; acid number of 0.4208 mg KOH/gram; density of 0.8838 gram/cm3, viscosity of 3.0617 mm2/s and water content of 1.17%.

“…Secara umum, keuntungan metode pencucian kering antara lain mempersingkat waktu proses pemurnian biodiesel, mengurangi jumlah air yang digunakan, mengurangi timbulan limbah, dan menurunkan biaya operasional. Selain itu, konsumsi energi metode ini adalah 23% lebih kecil dibandingkan dengan metode pencucian dengan air [14].…”

Biodiesel can be made by utilizing used cooking oil through a chemical process, namely through a transesterification reaction, namely changing the oil (triglycerides) into fatty acid methyl esters. Washing must be done to remove the remaining impurities in biodiesel. The dry washing method is purification by utilizing the adsorption process to remove impurities in crude biodiesel. Bentonite is an alternative adsorbent that can be used as dry washing in the biodiesel refining process because it is cheaper, abundant in nature and has a layered structure with the ability to swell. The purpose of the study was to determine the ability of bentonite activated with acid as a dry washing agent in biodiesel purification. The research method used is the dry washing process method using bentonite adsorbents. The application of bentonite adsorbent as much as 6 grams with a contact time of 3 hours is the best operating condition to produce biodiesel with a pH of 6 and a clarity value of 96.7.

“…In recent research reported [14], linseed biodiesel was filtered using 100kDa molecular weight cut off ratio Poly Vinyl Dene Fluoride membrane to filter out monoglyceride. Biodiesel washing reactor was designed with ultrafiltration ceramic membrane for washing biodiesel made from palm oil [15]. In another investigation, a reactor was fabricated using carbon porous membrane having a pore size of 0.05 micrometer that separated the emulsified oil droplets of canola oil-based biodiesel [16].…”

Considering the virtue of the environment, the usage of biofuel blended fossil fuels for transportation has speeded across the globe. The quality of biodiesel plays an important role in the efficiency of a diesel engine. The biodiesel by transesterification method produces crude biodiesel. The crude biodiesel contains impurities like glycerol, alcohol, catalyst, and water molecules that are suspended in the Fatty Acid Methyl Ester (FAME) molecule. These impurities in the crude biodiesel affect the performance of the engine with improper spray pattern, corrosion, nozzle blockage, affecting autoignition temperature and increase the NOx emission in exhaust gas. The shelf life of the stored biodiesel also gets affected by these left-over impurities. In order to overcome and refine it, a novel filtration of crude biodiesel using reverse osmosis membrane has been discussed. ANSYS Finite Element Analysis has been carried out for this investigation. Pressure in an increasing sequence of 100 kPa to 1500 kPa has been varied for the analysis of this multiphase flow through porous medium. The changes in velocity, pressure, density, and viscosity have been observed through the obtained contours. The results include the variation of velocity, density, and viscosity with reference to pressure. The study also indicated that the minimum pressure required for the filtration is 500 kPa. Further, the increase in viscosity and density after the filtration zone, represents the increase in the volume fraction of the impurities.
