Macromolecular Orientation of Rigid Dumbbells in Shear Flow
We use molecular modeling to study the non-equilibrium behaviour of polymeric fluids. Specifically, we explore the macromolecular orientation induced by shear flow fields. We choose the simplest molecular model, the rigid ... -
Mathematical model for ethane pyrolysis in an industrial furnace
(2014-09-23)Ethane pyrolysis is an important industrial process that occurs by passing ethane and steam through radiant coils (tubes) in gas-fired furnaces to produce ethylene and other light olefins. Undesirable side reactions that ... -
A Mathematical Model for the Devolatilization of EPDM Rubber in a Series of Steam Stripping Vessels
(2012-10-24)A steady-state mathematical model for the stripping section of an industrial EPDM rubber production process was developed for a three-tank process, and two four-tank processes. The experiments that were conducted to determine ... -
Mathematical Modeling of Arborescent Polyisobutylene Production in Batch Reactor Using Novel Material Balance and Monte Carlo Methods
(2014-10-02)Four mathematical models have been developed to describe copolymerization of inimer and isobutylene via living carbocationic polymerization in batch reactors. In this system, there are six different propagation rate constants ... -
Mathematical Modeling of Arborescent Polyisobutylene Production in Continuous and Semi-Batch Reactors
Mathematical models are developed for arborescent polyisobutylene (arbPIB) production in continuous-stirred-tank and semi-batch reactors. The objective of the research is to assess how reactor type influences final polymer ... -
