Abstract

Biodiesel is a type of renewable fuel which is biodegradable and does not emit hazardous material. However, biodiesel is prone to oxidation and could cause problem in the engine. Addition of antioxidant tert-butylhydroquinone (TBHQ), as one of the best antioxidants, is able to prevent oxidation. Nevertheless, antioxidant is also partially soluble in biodiesel as it is partially polar while biodiesel is very nonpolar and could cause undesired sedimentation. To overcome this insolubility problem, addition of antioxidant and surfactant combination is used in the previous study. Antioxidant TBHQ and surfactant glycerol monostearate (GMS) were proven as the best combination. This combination showed a satisfying result in terms of induction period, its performance almost equals Baynox, the commercial antioxidant. This combination has the potential to be commercially manufactured. However, since it is a new research, no upscaling design have been made. Therefore, in this thesis the design of the industrial process of this new additive is made. The designed plant capacity is 480 tons/year. The economic feasibility shows that this project is profitable.
