Technoeconomic study of supercritical biodiesel production plant

Over the last years, biodiesel has gained more market due to its benefits and because it appears as the natural substitute for diesel. r, the highest cost of this process is associated with the raw material employed, making it a less competitive and more expensive fuel. Therefore, research is being done in order to use low price raw material, such as acid oils, frying oils or soapstocks. s work, a biodiesel production plant was developed using supercritical methanol and acid oils as raw materials. This technology was compared with some other alternatives previously described with the aim of making a comparative study, not only on the technical aspects but also on the economic results. ess simulator was employed to produce the conceptual design and simulate each technology. Using these models, it was possible to analyze different scenarios and to evaluate productivity, raw material consumption, economic competitiveness and environmental impacts of each process. gh the supercritical alternative appears as a good technical possibility to produce biodiesel, today, it is not an economic alternative due to its high operating costs.
