OMS developed Model based tanks quality tracking system integrates tank qualities using infrequent lab analysis,  upstream process unit analyzers or multiplexed analyzer at tank inlets. This facilitates blend recipe optimization using more accurate blend component qualities.

The concept has been field proven in Singapore refining with a reported savings of 2.5 Millions Dollars/year from open blending system for Diesel and Kero blend products.

The results are published in Hydrocarbon Engineering.
