Scale up reaction
WebThe reviews scale-up of chemical reactors considers the dimensionless parameters, mathematical modeling in scale-up, and scale-up of a batch system. The objective of a scale-up in a reactor design is to determine the criteria on which to base the transfer of the laboratory scale into a full-scale commercial unit. Additional investigations are ... WebThe scale-up of chemical reactions is not simply a case of using a larger reaction vessel – many factors need to be considered just to keep reactive chemicals contained, let alone achieve successful scale-up for the desired product. Consequently, scale-up requires specially trained chemists, indeed often a whole department in larger companies.
