Introduction to Aspen PIMS for Petrochemical Planning

Build petrochemical planning models in PIMS to generate optimum plans including evaluating alternative feeds, process units, products, and markets. Develop Linear Programming (LP) structure in order to solve optimization problem including interpreting and analyzing the LP solutions. Review data tables and structures required to build and maintain a model. Understand the structures for developing typical petrochemical process units like pooling, delta based models, and compositional recursion.

Audience:

Technical as well as non-technical personnel who have no experience in linear programming. This course also provides a person who is knowledgeable in LP (but not necessarily knowledgeable in Aspen PIMS) with a quick way to gain a good understanding of the system.
