In refinery simulation and petroleum refining digital twin applications, evaluating a fuel blending operation requires considerably more information than simply measuring inlet and outlet flow rates. A
ProductMixer continuously decides which incoming streams satisfy
product quality specifications, determines how much of each stream is accepted into the final blend, rejects non-compliant material, injects additives, and verifies that the resulting product satisfies all
blending constraints. These operations cannot be evaluated using conventional flow statistics alone. ProductMixer Statistics are collected regardless of the selected blending algorithm and are available for both
Automatic Product Blending and
Manual Product Blending modes.
To support engineering analysis, ProductMixer Statistics combines process monitoring, blending optimization, and quality-control information within a single API for refinery simulation models. In addition to monitoring material flows, it evaluates
product properties, tracks rejected streams, reports
additive consumption, and verifies compliance with
blending constraints. Together, these metrics provide a complete picture of the blending process and allow engineers to understand not only how much product is produced, but also why the optimizer selected a particular blending solution. For an overview of ProductMixer capabilities, see the
ProductMixer Complete Guide.
The Anylogic based
Petroleum Refining Library organizes these performance metrics into several logical categories covering incoming flows, blended product statistics, quality constraints, additives, and optimization summary information. Together, these statistics provide a comprehensive framework for monitoring refinery blending operations, validating optimization results, and analyzing ProductMixer performance throughout the simulation. Although this article describes the available performance metrics, their generation and retrieval are integrated into the ProductMixer runtime API. For details about runtime configuration, public methods, events, and advanced control, see

ProductMixer performance simulation for an interactive example.
