Modeling of Polyolefin Polymerization in Semibatch Slurry Reactors: Experiments and Simulations

Optimal Temperature Control of Semibatch Polymerization Reactors

B Abstract. Recently, in a paper of Chylla and Haase 2], a model of a multi-product semibatch polymerization reactor has been developed which is representative of those found in the speciality chemical processing industry. One of the aims in these processes is to keep a certain reaction temperature setpoint, in order to t the quality requirements for the polymer. In the present paper, the optim...

Modeling and optimization of tubular polymerization reactors

Batch and semibatch catalytic reactors (from theory to practice)

A short review of batch reactor theory and practice is the subject of this paper. Based on unsteady state mass and energy balances, the mathematical set of equations describing the time-dependent behaviour of a batch or semibatch reactor is reported. The attention is focused on some examples of batch reactor experiences (experimental studies, scale-up techniques, industrial operation and optimi...

Simulation of Styrene Polymerization Reactors: Kinetic and Thermodynamic Modeling

A mathematical model for the free radical polymerization of styrene is developed to predict the steady-state and dynamic behavior of a continuous process. Special emphasis is given for the kinetic and thermodynamic models, where the most sensitive parameters were estimated using data from an industrial plant. The thermodynamic model is based on a cubic equation of state and a mixing rule applie...

Modeling of the Fischer–Tropsch synthesis in slurry bubble column reactors

A multicomponent one-dimensional dynamic mathematical model for the reacting slurry systems with a change in gas flow rate due to the chemical reaction is developed. A change in gas flow rate caused by the chemical reaction is modeled using the overall gas mass balance. Thus, all relevant chemical species are included in the model. Linear first-order reaction kinetics is considered. The gas pha...
