Patent ID: 8398942

Claim:
A mobile plant for self-sustainable biodiesel production of configuration and arrangement of components on a rigid frame, chassis, on wheels, with one or two axels, comprising a vegetable oil storage container; a methanol or ethanol storage container; an electric generator with diesel engine; a unit of oil extraction by mechanical pressing; a filtration unit for vegetable recycling oils or in natura oils, optionally a stage to correct the pH of the oil; electrical control panel for starting and stopping of energy of all electrical system of motors, pumps and heating; electrical panel to activate lighting and electrical supply outlets an in natura vegetable oil storage container for storing vegetable oils from a process of mechanical pressing of oilseeds, followed by filtration; storage container for waste vegetable oil; a storage container for alcohol, the alcohol containing up to eight carbon atoms in its structure; storage container for biodiesel produced and purified; first reactor with controlled stirring and heating for the refining reactions or transesterification of vegetable oil; optionally a second reactor with controlled stifling and heating; a first settling tank for phase separation of refining or transesterification of vegetable oil, biodiesel or just reacted; a second settling tank operated in parallel to the first settling tank; a third settling tank operated in parallel to a first storage container of the dense phase produced in the transesterification reaction and separated; the first settling tank, the second settling tank or the third settling tank with heating to recover the methanol or ethanol; a second storage tank using heating to recover the unreacted methanol or ethanol in the transesterification step; heat exchanger for condensing the vapor of methanol or ethanol produced at the first storage container and the second storage container; a cold water container; a hot water tank with heating controlled to provide hot water to the process of purifying biodiesel; a liquid-liquid extraction column for hot washing the biodiesel produced under the polishing process; a drying tower of washed biodiesel with controlled heating, reduced pressure and circulation system and pumping of the processed liquid; a storage container of clean water for powering plant and laboratory; containment box of water from the process, coming from the stage of glycerin extraction from biodiesel into the liquid-liquid extraction column or from coolant liquid in the heat exchanger; and a box to contain the overflow of the containment box, while full loaded.
