Abstract
Mathematica has been used as an environment for object modelling of a new chemical pulping process. The usability of Mathematica has been enhanced by integrating it into an Information System (IS) supporting chemical process development. The implementation of IS is based on a new phenomenon driven process design methodology. The integration into the IS results in an easy way to change and give process structures for Mathematica and makes Mathematica an attractive alternative compared to commercial simulators.
