摘要： System and method for determining total inventory of batch and continuous biomass inventories in a biofuel production process. Measured biomass inventory values are received, including batch inventories from multiple batch fermenters and at least one continuous beer well inventory. The values are premised on a controlled vapor pressure of the batch fermenters and beer well(s), where the pressure fluctuates in an uncontrolled manner. A measured vapor pressure for the batch fermenters and beerwell(s) is received, and pressure compensated inventory values determined based on the measured inventory and pressure values. Measured biomass input flow to the batch fermenters and output flow from the beerwell(s) are received, and are premised on a constant biomass temperature and density, where biomass temperature and density fluctuate in an uncontrolled manner. The total inventory of batch and continuous inventories is determined based on the measured flows and the pressure compensated inventory values, and stored.

摘要： System and method for managing fermentation feed in a biofuel production process, comprising a dynamic multivariate predictive model-based controller coupled to a dynamic multivariate predictive model. The model is executable to: receive process information, including water inventory and biomass information, from the biofuel production process; receive a specified objective for the fermentation feed specifying a target biomass concentration; and generate model output comprising target values for a plurality of manipulated variables of the biofuel production process, including target flow rates of water and/or biomass contributing to the fermentation feed in accordance with the specified objective. The controller is operable to dynamically control the biofuel production process by adjusting the plurality of manipulated variables to model-determined target values to stabilize water/biomass balance in the fermentation feed in accordance with the specified objective, including the specified target biomass concentration.

摘要： System and method for managing batch fermentation in a biofuel production process. A nonlinear control model of yeast growth and fermentable sugar concentration for biofuel (e.g., fuel ethanol) production in a batch fermentation process (pure and/or fed-batch fermentation) of a biofuel production process is provided.

摘要： The present invention provides novel techniques for controlling batch reaction processes. In particular, a parametric hybrid model may be used to parameterize inputs and outputs of batch reaction processes. The parametric hybrid model may include an empirical model, a parameter model, and a dynamic model. Critical quality parameters, which are correlated with, but not the same as, end-of-batch quality values for the batch reaction processes may be monitored during cycles of the batch reaction processes. The quality parameters may be used to generate desired batch trajectories, which may be used to control the batch reaction processes during the cycles of the batch reaction processes.
