Blending is a process to combine multiple components to meet the required specifications of salable products (e. g. different types of diesel or gasoline). The components are typically fractions from crude oil distillation as well as products from processing plants such as reformer, isomerization, hydrocracking, cat-cracking, coking etc.

In contrast to the direct sale of individual components, the blending of several components allows the specific and individual adjustment of the properties of the products. Thus, it is possible to produce the individual components in such a way that the process plants are operated at the most economical point.

The aim of the blending process is the provision of a recipe by controlling the flow. The start recipe is determined based on a mixed model (mathematical relationships between component properties and product properties) to fulfill the specification of the product. Analyzes during the blending process correct deviations of the real mix from the blended model so that the corrected recipe meets the specification.

VTA has great experience in the design and construction of blending equipment. It has been shown that a thorough analysis of the blending task (component structure and availability, production scenarios, product specifics, mixing models) prior to the construction of a blending facility is crucial for the efficiency of the overall system. VTA offers such studies in which, together with the plant operators, an optimal solution for the respective situation is worked out. In addition to such studies, VTA also offers all required services in the blending area, from engineering through automation to turnkey systems. In addition to the components described above, VTA also offers its own software tools that are used to optimize or integrate the blending systems in refinery planning.

Always there for questions.
