SELCONT - Optimized Selectivity in a Semi-Continuous Reactor

5 SELCONT - Optimized Selectivity in a Semi-Continuous Reactor 

Keller (1998) describes the semi-continuous reaction process of a vinylketone K with lithium acetylide LA to yield lithium etinolate LE an intermediate in the vitamin production. In an undesired side reaction an oligomer byproduct BP is produced. During the process, reactant K is fed to the semi-batch reactor at a rate to maximize the selectivity for LE.

The total balance for the semi-batch reactor assuming constant density is 

An objective function can be defined with respect to the positive impact by the productivity of LE and the negative contribution by that of BP weighted by a factor a.
