Abstract

The high viscosity of heavy oil can cause various problems below and on the surface so that the reduction of the viscosity of heavy oil becomes important. The cause of the high viscosity of heavy oil is closely related to its components, one of which is asphaltene. Nanotechnology has emerged as a petroleum viscosity reduction technique that is technically competitive with conventional processes. This study aims to analyze the effect of silica nanoparticles on reducing the viscosity of heavy oil. Silica nanoparticles have been synthesized using the co�precipitation method. The synthesis process begins by reacting silica sand with NaOH and then titrated with HCl. The titrated silica gel was then dried and silica A nanoparticles were obtained. Silica A nanoparticles were then sonicated to obtain silica B nanoparticles. Crystal structure characterization showed that the synthesized silica nanoparticles had an amorphous type of structure with a peak of 2? = 21.90° for silica nanoparticles A and 2? = 23.30° for silica nanoparticles B. The results of particle size characterization showed that the size of silica A nanoparticles was 181.2 nm. and silica B nanoparticles is 326 nm. The viscosity of heavy oil can be reduced by 17% using silica nanoparticles A and by 19% using silica nanoparticles B with a variation of 1 gram of silica nanoparticles. Asphaltene content decreased with viscosity. The best reductiom in asphaltene content was obtained at a variation of 1 gram for both silica nanoparticles with an initial asphaltene content of 5,771 gr to 5,017 gr or 13% for nanoparticle A and an initial asphaltene content of 5,792 gr to 4,933 or 14% for nanoparticle B
