Fast payback with APC
As a process licensor and catalyst supplier, Axens has first-hand knowledge of the best strategies and approaches for APC projects. Performance Programs (P2) makes clients’ plants perform better and more safely with APC by:
- extending catalyst performance and service life
- reducing utility and logistics costs
- saving energy and decreasing carbon dioxide emissions
- avoiding the problems caused by off-specification products.
As product specifications become increasingly stringent, APC can pay off handsomely. Axens combines the ability to manage all phases of APC projects with the use of powerful computational resources; these include inferential modules, proprietary software packages, multivariable predictive controllers and an extensive database of chemical reaction kinetics and thermodynamic properties.
