Solution: Separator and Mixer for Petroleum Refining Simulation
A Light Separator is a simulation element used in refinery simulation to distribute an incoming material flow between two outputs. The resulting flows can be routed to downstream process units, pipelines, storage, or other elements of a petroleum refining model. Light separator simulation helps represent controlled flow distribution within refinery process models and can be used as part of larger refinery simulation and digital twin systems. The Light Separator is part of the broader group of separation and mixing simulation elements. Unlike SeparatorLight, the Separator can divide a single incoming flow into any number of output flows.
The SeparatorLight component was specifically developed to solve the problem of guaranteed flow routing to a single output, which is not available with the standard AnyLogic Fluid Split component.
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.

Controlling Separator Simulation in Petroleum Refining
In a refinery simulation, the Light Separator provides several methods for controlling how the incoming flow is distributed between two outputs.
Setting the Flow Split
The setSplit() method sets the flow values assigned to the first and second outputs. The values do not need to be normalized.If both values are positive, the separator uses proportional split mode. If one output value is zero, the separator switches to neutral flow mode. Calling setSplit() also disables fixed-limit split mode.The split can be specified as two individual values or as a two-element array: [firstOutput, secondOutput].
Limiting the Second Output
The setFixedSplitFlow2() method sets the maximum flow allowed through the second output, defining the secondary output flow limit. When fixed-limit split mode is enabled, the flow through output 2 is limited to the specified maximum, while the remaining available flow is automatically routed to output 1. Fixed-limit split mode is controlled by flowLimitSplitEnabled, while output2FlowLimit defines the maximum flow assigned to output 2. Both settings can also be loaded from an external INI file.
Other Flow Controls
The selectOutput1() method provides direct material flow control by routing the entire incoming flow to either the first or second output. The setSpeedLimit() method limits the maximum input flow rate, while getSpeedLimit() and resetSpeedLimit() allow the current limit to be read or reset. The resetState() method removes active flow split restrictions, restores the maximum input flow limit, and returns the separator to neutral flow mode. The input valve can be controlled with setClosed() and checked with isClosed(). The current separation ratios can be obtained using getSepRatios() or getSepFactors(). The isAllToFirst() method checks whether the entire incoming flow is currently directed to the first output, indicating that no flow is routed to the second output.
Properties and Events
The inputProductId property identifies the product associated with the input flow, while useIniSettings enables loading configuration for the simulation model from an external INI file. The onAfterInitialize() event is triggered after initialization. The onSpeedChange() event is triggered when the input flow rate changes and provides the new flow rate.

Light Separator Statistics
The Light Separator provides statistics for monitoring incoming and outgoing material flows, separation ratios, and active flow limitations. The Separator provides the same comprehensive statistics for monitoring and analyzing its operation, including input and output flow data and flow distribution between product streams. Access to the separator light statistics is provided through the internal statistics variable.
Input Statistics
The input statistics object provides methods for input flow monitoring, including the incoming flow and its current flow limit. The main methods below return flow values, check whether material is entering the separator, and generate formatted input summaries. SeparatorLight uses the SingleFlowProvider interface to provide basic statistics and flow-related information for its single incoming flow.

Conclusion
Light Separator simulation provides configurable flow distribution between two outputs in refinery simulation and digital twin models. The incoming material flow can be split proportionally, limited at the second output, or routed entirely to one output within a petroleum refining simulation. Built-in statistics support monitoring of flows, separation ratios, and active flow limitations.
