Profit optimizing

The models presented so far, helped to determine profit-optimal plans by volumes and values. However, the optimization can result in underutilization of capital-intensive production resource, which is not a desired state. In this situation two questions are raised mainly by sales and marketing ... 

Which sales prices are profit-optimal fully utilizing a specific capacity ... 

Global profit optimization consistent with profit and loss statements demonstrates how to integrate the value and volume views in controlling, sales marketing, supply chain management, production and procurement.

Tubular reactors do not necessarily operate under isothermal conditions in industry, be it for reasons of chemical equilibrium or of selectivity, of profit optimization, or simply because it is not economically or technically feasible. It then becomes necessary to consider also the energy equation, that is, a heat balance on a differential volume element of the reactor. For reasons of analogy with the derivation of Eq. 9.1-1 assume that convection is the only mechanism of heat transfer. Moreover, this convection is considered to occur by plug flow and the temperature is completely uniform in a cross section. If heat is exchanged through the wall the entire temperature difference with the wall is located in a very thin film close to the wall. The energy equation then becomes, in the steady state ... 

In the context of improving the efficiency of use of natural resources and of profit optimization, the question arises whether a chemical process can explicitly be monitored in real time by low field NMR spectroscopy. Typical requirements are A resolution of about 0.1 ppm which is often sufficient to detect and quantify concentrations of reactants, a measurement time short enough for temporal resolution of the reaction (several 10 s). Questions like pre-magnetization and accuracy have to be addressed. The most obvious way to follow the reaction by NMR is via a bypass line. Representative sampling is here a crucial point, which was addressed in a recent publication. The esterification reaction of...
