Dynamic mathematical modeling for control of film gauge for Tedlar® film casting

The objective of the proposed research project is to develop a mathematical model that can be used to predict, monitor and control the thickness profile of extruded Tedlar® film, particularly during product transitions and batch switches.  Development of this model will require a detailed understanding of the extrusion and film casting process, as well as identification of key polymer and process parameters that influence film gauge.  Existing and new process data from grade and batch changes will be collected and used to explore the influence of polymer properties and process conditions on

Developing Microkinetics Oxidation Models

The emissions of NOx and SO2 are subject to increasingly severe environmental regulations. In an effort to reduce the amount of NOx and SO2 emitted by DuPont’s industrial facilities, the intern will develop new capabilities in NOx and SO2 absorption modeling. During the project, the intern will begin by learning the ChemKin™ software, which he will apply to simulate the absorption of NOx and SO2 into caustic. Caustic is a liquid solution currently used to “clean” exhaust gases from NOx and SO2 in wet scrubber equipment.
