  • Energy optimizer for dehydrating biofuels through distillation towers and molecular sieves
    Patent number: 9014858
    Abstract: The present invention provides novel techniques for controlling the balance between energy usage and biofuels dehydration between a distillation process unit and molecular sieves with model predictive control technology. In particular, the present techniques are presented in the context of biofuel production, wherein control of the balance between energy usage and water removal in biofuel production may be optimized. However, the present techniques may also be applied to any other suitable applications, such as liquor processing, where energy may be used to remove water from the liquor.
