Influence of pressure in RO filtration of crude biodiesel

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