By a News Reporter-Staff News Editor at Science Letter -- Investigators publish new report on Science. According to news reporting out of Magdeburg, Germany, by NewsRx editors, research stated, "The simulated moving bed (SMB) technology is increasingly applied in various fields, ranging from the food to the pharmaceutical sectors, for the chromatographic separation of fine (bio)chemicals. In this study, an adaptive controller acting on the fluid flow rates and commutation period is used to regulate the spatial location of the adsorption and desorption waves, and in turn the purity and productivity of the raffinate and extract effluents."
Our news journalists obtained a quote from the research from Otto Von Guericke University, "This controller is based on a simple discrete-time model of the concentration fronts movement, derived from wave theory. A simple parameter adaptation scheme makes this controller robust to parameter uncertainties and drifts, and allows process start-up with minimum a priori knowledge of the separation parameters. In this study, the performance of the controller is demonstrated for two different applications: the separation of fructo-oligosaccharides (linear isotherms) and cyclopentanone-cycloheptanone (competitive Langmuir isotherms)."
According to the news editors, the research concluded: "Different plant/sensor configurations are also examined, indicating the potential of the control strategy even with reduced measurement information."
