MixerLight Simulation in Petroleum Refining
A MixerLight is a simulation element used for mixer simulation in petroleum refining to combine two incoming material flows into a single output. The mixed flow can be routed to downstream process units, pipelines, storage, or other elements of a petroleum refining model. Mixer simulation in petroleum refining supports controlled material flow mixing within refinery process models and digital twin systems. The MixerLight is part of the broader group of separation and mixing simulation elements. Unlike MixerLight, the Mixer can combine multiple input flows into a single output flow.
The MixerLight component was specifically developed to ensure guaranteed material flow from a selected input, allowing the model to prioritize one inlet when combining flows.
Controlling Mixer Simulation in Petroleum Refining
In petroleum refining simulation, the MixerLight provides several methods for controlling how two incoming material flows are combined into a single output.
Setting the Mix Ratios
The setMerge() method sets the relative flow values for the first and second inputs. The values do not need to be normalized. When both values are positive, the mixer uses proportional merge mode. The mix can be specified as two individual values or as a two-element array: [firstInput, secondInput].
Other Flow Controls
The MixerLight provides direct control of the incoming flows and the resulting mixed stream. The setSpeedLimit() method limits the maximum outlet flow rate, while getSpeedLimit() and resetSpeedLimit() allow the current limit to be read or reset. The resetState() method removes active flow restrictions and restores the mixer to its default operating state. Individual input valves can be controlled with setClosed() and checked with isClosed(). The current mix ratios can be obtained using getMixFactors() or getMixFactorsMap().
Properties and Events
The connectAfterStart property defines whether the MixerLight connections are established after the simulation starts. The inputFlows and outputFlow properties provide access to the current inlet and outlet flow values. The onAfterInitialize() event is triggered after the component is initialized, while onSpeedChange() is triggered when the flow rate changes and provides the new flow rate.

MixerLight Statistics
The MixerLight provides statistics for monitoring material flows, mix ratios, and flow limitations in refinery simulation models. The statistics interface is divided into input and output statistics, providing access to flow values and formatted summaries. Unlike MixerLight, Mixer provides a comprehensive set of statistics for analyzing its operation, including individual input flows, flow ratios, active products, mix factors, total output flow, maximum flow rate, and outlet valve state.
Input Statistics
The input statistics object provides methods for monitoring the flow from both mixer inlets and their combined flow.

Conclusion
Mixer simulation in petroleum refining allows two incoming material flows to be combined into a single output stream. MixerLight supports proportional mixing, flow-limited merge operation, inlet flow control, and outlet flow limits. Built-in statistics provide information about individual and total inlet flows, the resulting outlet flow, mix ratios, and active flow limitations, supporting monitoring and analysis within refinery simulation and digital twin models.
FAQ
1. What is MixerLight in petroleum refining simulation?
MixerLight is a simulation element that combines two incoming material flows into a single output stream.
2. How does MixerLight control the mixing of two flows?
The incoming flows can be combined using configurable mix factors and proportional merge mode.
3. Can MixerLight limit the flow from one input?
Yes. Flow-limited merge mode can limit the flow from the second input while allowing material to continue flowing from the first input.
4. Can the outlet flow be limited?
Yes. The maximum outlet flow rate can be controlled using setSpeedLimit(). The current limit can be obtained with getSpeedLimit() and removed with resetSpeedLimit().
5. Can individual inputs be opened or closed?
Yes. Input flow can be controlled using setClosed(), and the current valve state can be checked with isClosed().
6. What statistics are available?
MixerLight provides statistics for individual and total inlet flows, outlet flow, inlet contribution percentages, mix ratios, flow-limited merge mode, and outlet flow limitations.
