Special Report: Process/Plant Optimization

Increase product value through process modeling

Using a rigorous refinery-wide simulation, a refiner moved more low-value products into value-added end products

A model of a refinery is more than the sum of the parts. The interactions between processing units determine true profitability from feedstock, products and utilities pricing. By applying rigorous kinetic nonlinear models, refiners can exploit all opportunities to maximize plant operations and profitability while boosting productivity. A sophisticated, kinetic non-linear models can be invaluable when attempting to accurately predict outcomes from proposed operating changes. The use of a rigorous, refinery-wide detailed simulation model can extrapolate specific unit's behavior accurately. These models also account for the interactions between each unit of the total process. True profitabili
