Research Interests
Dynamic Modelling and Reactor Control of Polymerization Processes
- The objective of my research is to develop a detailed mechanistic mathematical model in order to simulate isothermal and non-isothermal emulsion copolymerization of AN-Bd (Nitrile Rubber), in batch, continuous, and trains of continuous reactors (CSTRs). The goal is to develop a practical tool to predict polymer production rate and product quality (molecular weight averages and branching characteristics) on an industrial scale. Model predictions will include conversion levels and polymerization rate, copolymer composition, number- and weight-average molecular weights, tri- and tetra-functional branching characteristics, and the number and average size of the polymer latex particles. Both 'cold' (low temperature range between 0 to 10ºC) and 'hot' (around 50ºC) recipes will be tackled.
- The long-term objective of my research is geared towards plant simulations and subsequent model-based applications on-line. The first application will involve the testing of non-linear model-based state estimation and control schemes for an industrial NBR continuous reactor train (in collaboration with industrial personnel). The second application will involve using the model as a storehouse of prior process knowledge for the implementation of a Bayesian sequential design of emulsion copolymerization plant-wide experiments. This will lead to a larger systematic study of multi-component polymerizations in an industrial environment.
