Blend optimization integrated into refinery-wide strategy

To achieve the highest benefit from the optimization of product blending, the blending support systems should be integrated with the systems that support planning and scheduling functions. Texaco Refining & Marketing Inc. has been extremely active in blend optimization and the integration of this function into the refinery-wide operating strategy at its refineries. Here is how Texaco has integrated the blending support system with the off-line upstream functions of scheduling and planning. Also discussed is the use of the system in a real-time, on-line environment, and the relationship between blend optimization and the downstream functions of control and reporting.
