Weboperation and optimal performance of this reaction within a CSTR, the following design considerations must be taken into account: reactant flow rate, reactor sizing, reaction kinetics and mixing. Reducing the flowrate of the reactants will result in a higher conversion due to the increased residence time, but this will sacrifice the overall ... WebThe design equation for the CSTR is developed from a substrate balance over the reactor at steady state 17 where F refers to the volumetric flow rate and S R to the substrate in the feed reservoir ... The design equation which predicts conversion in a plug flow enzyme reactor in terms of residence time (τ) is given in Equation 6.37. WebBy choosing random numbers, R, from the uniform interval [0, 1] to equal to the values of in Eq.
