Recent Studies from Colombia National University Add New Data to Chemical Engineering

February 19, 2014

By a News Reporter-Staff News Editor at Journal of Engineering -- Investigators publish new report on Chemical Engineering. According to news reporting originating in Manizales, Colombia, by VerticalNews journalists, research stated, "One means of increasing the productivity of microbiological processes is to remove toxic inhibiting products as they are formed through extractive fermentation. The aim of this work was to develop a short-cut tool to allow the design and analysis of extractive fermentation processes."

The news reporters obtained a quote from the research from Colombia National University, "For this purpose, a rigorous model considering both the fermentation kinetics and the application of a thermodynamic phase equilibrium model was developed for batch and continuous regimes. The outcomes and regularities found during the analysis of extractive fermentation using the rigorous model were considered to develop the short-cut tool. The short-cut method was based on the principles of topological thermodynamics and was applied to several case studies in this article."

According to the news reporters, the research concluded: "This method enables preliminary information to be acquired and used during the subsequent rigorous simulation, enabling a decrease in the calculation efforts and in the number of experimental runs."
