Optimization of Temperature on The Concentration of a Mixture of Substances in Liquid Waste Treatment Process Palm Oil

One process of mixing two types of chemicals (reactants) or more to produce a product can be seen in the processing of palm oil waste. In the processing of palm oil waste two reactants or more mixed in a reactor produce a chemical process. Where the chemical process, conducted to produce a product in this case is a fertilizer. When in the chemical process the reactant concentration is enlarged, the reaction rate in the chemical reaction will be faster. So it will produce a more optimal product. As is known if if the temperature is raised then the reaction rate will run faster. When the temperature is raised, the reactant particles will move faster so that the kinetic energy is greater. Therefore, in the completion of this study use Newton's law and Fourier's law. From these two laws will be obtained partial differential equations associated with temperature and concentration of substances. From the equation we will get the optimum temperature in raising the right temperature of 334 K. The settlement is obtained from finite element method applied in simulation with COMSOL Multiphysic program. (paper)
