Sažetak

The mathematical model of the dynamics of thermohydraulic processes in
a high pressure tubular reactor for production of low-density polyethylen
has been presented. The equations of the mathematical model have been
formulated based on one-dimensional fluid flow assumptions. Polyethylen
production has been modelled by multivaribale, nonlinear function defining
dependence on temperature, concentration and flow velocity. Simulations
results of typical operating conditions (start-up, regular operation, transient
response to coolant temperature changes) provide a realistic description of
the process.
