Berlin, April 2010Plantwide Optimizing Control for the Continuous Bio-Ethanol Production Process v AbstractIn this work, the Plantwide Control (PWC) problem of a continuous bio-ethanol process is investigated from a Plantwide Optimizing Control (PWOC) perspective. A PWOC methodology is proposed which addresses this problem by integrating real-time optimization and control for optimal operation. The PWOC methodology consists of two main tasks. The first is a local control-oriented task related to the identification and design of necessary local control loops required for satisfying the primary objectives of the process (e.g. safe operation, environmental and equipment protection, etc.). The second is a Plantwide control-oriented task in which the available control degrees of freedom are used for maximizing the process profitability. This means that, excluding the local loops, no pre-defined set points will be either regulated or tracked. The core of the PWOC methodology proposed is the formulation

Uncertainties in the Bidirectional Biodiesel Supply Chain

“…In line with the conclusions of Ochoa et al (2010) and Aikman and Pridmore (2001), it should be stated that lack of buyersupplier knowledge forms an important source of production uncertainty. The lack of knowledge related to the measurement of biomass quality by the local buyer-suppliers has become evident for instance, as only one of the interviewed rubber farmers was able to describe a quality measurement process.…”

“…Education is shown by Aikman and Pridmore (2001) to be an important factor leading to externally caused machine failures, either through improper machine usage or by affecting the quality of inputs delivered (Ochoa et al, 2010).…”

“…Nevertheless, it might also be due to actions of other supply chain actors, e.g. through the delivery of poor quality inputs (Ochoa et al, 2010) or poor infrastructural quality (Richard, 2010). Finally, the resolution of machine failure as well as the overall operation of the production unit requires a certain educational level of the users and actors in the supply chain, which might relate to the overall educational level in a region (Aikman and Pridmore, 2001).…”

Simulation and Control of Enzymatic Hydrolysis Reactor of Soluble Potato Starch by Aspergillus Niger Glucoamylase for Fermentation Process Feed

“…Instrumented with liquid level sensor to determine the reaction volume, its set-point was set to half of total volume and product concentration set-point to 60 kg.m -3 . For liquid level, a single-input-single-output (SISO) control loop was implemented in reason that it is a simple and reliable strategy for level control and was also successfully applied by Ochoa et al (2010a). Two different strategies were tested for product concentration, the first based on a SISO loop, comparing the process variable with set-point and actuating in enzymatic solution inlet flow because it is the most affecting variable to glucose concentration.…”

Fuel gas blending benchmark for economic performance evaluation of advanced control and state estimation

“…For example, Ochoa et al apply plant-wide one-level and two-level methods to a bioethanol production process, contrasting these to a more conventional decentralized RTO method [11]. Zavala et al explicitly account for forecasting uncertainty in the optimal control of energy systems [12].…”
