Special Report: Improving Process Control

Use techno-economic benchmark to review supply-chain models

Value profile of crude and high vacuum unit fractions is the key for crude selection and, thus, refinery profitability

Hartmann, J.C.M., Consultant

Planning the supply chain can be done with linear programming (LP). LP models provide a blueprint for: Supply of crude/ feedstocks Loading and operation of distillation/ treating/ conversion plants Routing of components Prediction of quantities and properties of the produced final products. On a monthly basis, the feasibility of this plan can be verified by comparing it with actual refinery performance. Differences between actual and plan are reduced by adjusting plant (property/ yield) data, revising constraints, and optionally by introducing safety margins and fiddling factors. The conventional LP does not consider
