The Petroleum Refining Library (PRL) Mixer is a component for combining multiple material flows in process simulation. Unlike MixerLight, which supports mixing two input flows, Mixer can combine any number of incoming material flows. It supports mixer simulation by merging incoming streams into a single output flow while preserving mass balance. The calculation of the resulting product composition and properties is performed by the ProductMixer component.
The Mixer can be used as an independent component or internally by other Petroleum Refining Library components, for example, to combine material flows from multiple Process Units, Tank Farms, pipelines, and other process streams in refinery simulation, oil and gas process simulation, refinery production planning, and process simulation models. Mixer provides extensive statistics for monitoring and analyzing multiple input streams, flow ratios, mix factors, output flow, and valve state during process simulation.

The Petroleum Refining Library Mixer differs from the standard AnyLogic Fluid Merge by supporting dynamic mixing of multiple material flows while preserving mass balance.
The priority mechanism in the standard AnyLogic FluidSplit and FluidMerge components does not guarantee that a higher-priority flow will be accepted or transferred in full. Although these components support neutral, proportional, and priority-based allocation algorithms, the priority mode represents a preference rather than a strict allocation rule.
The configured priority coefficients are incorporated into the objective function of the underlying linear programming (LP) flow-network model as penalty or benefit factors. As a result, in complex networks, the LP solver may allocate flow from a lower-priority connection if this produces a more advantageous overall solution.
The Petroleum Refining Library Mixer provides a different mechanism: guaranteed flow acceptance. A designated input can be treated as mandatory, ensuring that its available flow is accepted in full before the remaining capacity is allocated among other inputs.

How the Mixer Combines Material Flows
Unlike MixerLight, which combines two incoming flows, the Mixer can combine an arbitrary number of incoming streams into a single material flow. The total output mass flow is calculated from the incoming flows allowed by the current merge configuration.
Multiple Input Flows and Dynamic Mixing
The Mixer supports an arbitrary number of input flows. Input flows are defined through the FluidEnter[] inputFlows array, where each array element represents one input connection. However, the mass flow rates and material composition of the existing input flows can change dynamically during simulation. The resulting output flow is continuously updated based on the combined incoming mass flows and their respective material compositions, ensuring mass conservation throughout the mixing process. This makes the Mixer suitable for dynamic material flow modeling in AnyLogic refinery and oil and gas simulation models.
Mixer API
The Petroleum Refining Library Mixer API provides methods for flow connection, material flow mixing, throughput control, and dynamic Mixer configuration during simulation.
Connecting Flows
The connect() method is particularly useful when connectAfterStart is enabled and the flow connections must be created programmatically after model initialization.
Managing Merge Factors
Merge factors control how individual input flows contribute to the resulting mixed flow. They can be configured for all input flows using an array of factors, specified by product ID, or used to select a single product flow. When setMerge(int productId) is used, the specified product flow is assigned 100% of the available input.
Managing Mixer Throughput
The Mixer throughput can be controlled using an overall flow limit or individual limits applied to specific input flows. These flow constraints can be used in refinery production planning and process optimization scenarios.
Managing Mixer State
The Mixer state can be controlled dynamically during simulation. It can be closed to completely stop the flow or reset to restore its default operating state.
Conclusion
The Petroleum Refining Library Mixer provides a flexible approach to mixer simulation and dynamic material flow mixing in process simulation. It combines multiple incoming flows into a single output while preserving mass balance. Merge factors can be changed dynamically, flow limits can be applied to the entire Mixer or individual input flows, and the Mixer can be closed or reset during simulation. These capabilities make the Mixer suitable for refinery simulation, petroleum refining, oil and gas process simulation, production planning, process optimization, logistics, and digital twin models, including models that combine flows between Process Units, Tank Farms, storage systems, and pipelines.
