Column description

The column description, product specifications, total plant operation time, number and size of available storage vessels, etc. are given in Table 6.8. For proprietary reasons the names of the components in the feed mixture are disguised and thermodynamic data ore omitted. Relative product values and feed costs are given in Table 6.10 (operating costs have also been scaled).

The process model is given in Leversund et al. (1993). As the polymer product forms a separate solid phase, this was not included in the process model. The model includes mass and energy balances, column holdup and phase equilibria and results in a set of DAEs. All thermodynamic, physical properties are calculated from library subroutines. The column description and data for the process are given in Table 9.6.
