“…Rantow et al 128 allowing for the maximum allowable change in reactor temperature over two consecutive periods, the authors reported four optimal feed policies with corresponding profiles in temperature: varying the charge composition, overall time horizon, solvent, and initiator composition, the optimal temperature policy shown to be a gradually decreasing/increasing, resp. by not more than five degrees, whereas the decrease/increase, resp., occurred in terminal double bond/chain branching, resp.…”

After World War II, scientific investigations for processing in chemical batch reactors were started, for its “most adopted” application in the industrial sector. Taken from the industrial perspective, serious instances, unable to be endured, happen; hence, the process must be in control of, which impedes the realization of batch reactor objectives. Therewithal, with the evolution of large-scale optimization software packages, the “ease” to convert novel optimal control policies into industrial environment strategies, becomes realistic. This work presents a detailed bibliography on the optimal control functioning for reactor configuration named “stirred jacketed”, waged in batch/semi-batch processing of fine chemicals and polymers, along with methods according to this definition. To the author's knowledge, all the existing schemes are discussed, focusing on their strong points.

A reduced-order mechanistic polymerization model and its application in the design of a lowdimension multi-rate state estimator (soft sensor) for monitoring spectroscopic and chromatographic polymer properties are presented. A model reduction approach is used to simplify a method-ofmoments mechanistic model. Using this approach, the order (number of the state variables) of the model is reduced from 20 to 7. The soft sensor estimates spectroscopic and chromatographic polymer properties from (a) frequent measurements of the reactor temperature and the flow rates of monomer (n-butyl acrylate), initiator (t-butyl peroxy acetate) solution and solvent (xylene) feed streams, and (b) infrequent and delayed measurements of polymer number-and weight-average molecular weights and the concentrations of terminal solvent groups, terminal double bonds and short chain branches. The benefits of using the infrequent measurements in the estimation are shown. The soft sensor is implemented in real-time, and the calculated continuous estimates of polymer number-and weightaverage molecular weights and the concentrations of solvent, terminal double bonds and short chain branches are compared to the corresponding chromatographic and spectroscopic measurements.
