For the manufacture of biofuels of the second generation such as bioethanol, biodiesel or plant oil, Ekato is offering now solutions that have been developed together with the customer based on laboratory and pilot plant tests and can be reliably scaled up to production capacity. An entire series of several stirred tanks in continuous operation combines the advantages of a tube reactor that is under continuous operation. Due to the fact that the solids content and viscosity of the biomass slurry change during the process, it is possible with the cascade principle to intelligently combine the central impeller and close to the wall impeller with one another. For example, less expensive central impellers can be used – except in the first vessel – as the viscosity continues to drop from vessel to vessel as a result of the progressive hydrolysis of the basic raw material. As a rule, the viscosity is already low enough in the second vessel to operate without the cost-intensive close-to-the-wall impeller. Even replacing the first vessel with two intermittently operated vessels can additionally reduce the viscosity so that it is possible to use central agitators if the design provides this option.
