Motor fuels are complex products. Various diesel fuel and gasoline grades are prepared from a large range of individual blending components whose individual properties may be extremely variable over time. Each day, refiners must determine the blend recipe based on the properties, value and availability of those components, as well as the target specifications for the product. Once that is done, the operational challenge is to verify that the blended product delivered to the pipeline actually meets those contractually defined specifications. Variation in catalyst and unit operations, unrelenting cost pressures and an ever-wider range of crude oil feedstocks compound the challenge. No matter how daunting these factors are, it still remains the refiner’s job to manage all elements so that they are transparent to the pipeline operator.
