Abstract
With the burning of fossil fuels, new energy sources end up being required to prevent the increase of CO2 and consequently global warming. Microalgae come as an option because they produce biodiesel, which is a source of non-toxic, biodegradable fuel that releases cleaner gases to the environment. In addition, microalgae have the potential to produce hydrocarbons, which are similar to hydrocarbons of fossil origin. However, in order to make microalgae hydrocarbons an usable fuel, a purification process is necessary since the hydrocarbons when extracted are contaminated with microalgae pigments and lipids. One type of purification is the fractional distillation, however this process consumes a lot of energy and therefore there is a need for optimization, which can be done by mathematical modeling. Therefore, the objective of this work is the mathematical modeling of bath distillation hydrocarbons produced by microalgae. The methodology used was mass balance and energy by the volume elements method, which is based on the optimization of systems engineering of physical size of study. The advantage of this methodology is that consists of a simple sequence of validation of the model with necessary adjustments until the mathematical modeling reaches a value obtained experimentally. The simulations of the model describe the system well, correctly separating the proposed compounds at the beginning of the model. The model can be used for optimization of distillation after experimental validation.
