ProTRAX Improvement ‒ Initial Condition Groups

ProTRAX Improvement ‒ Initial Condition Groups

TREE VIEW: Using the new view options, users can organize initial conditions by group

RTEXEC now gives you the ability to place your initial condition (AV) files in groups, making it easier to organize and browse your initial conditions. Users can toggle between two views in the save and load dialog windows: List View and Tree View. This allows users to select initial conditions from a detailed list, or from collapsible groups.

The displayed initial condition files may be sorted by any column by clicking on the column header. For reference, the most recently accessed file is displayed in red.

The optional Subject field is also helpful for identifying AV files. This field is used to enter a description of the AV file for future use.

In the save and load dialog windows, the user can quickly add groups by right clicking on “AV Files” and selecting “Add Group.” Then, easily add initial conditions to each new group by dragging-and-dropping filenames into the group. A “(No Group)” heading is available for ungrouped initial condition files.

ProTRAX Improvement ‒ Initial Condition Groups

June 11, 2018

TRAX has delivered a carbon capture simulator for a 150 MW coal-fired unit that models the capture of the full flue gas stream.  The system provides both CO2 and SO2 capture, delivering the captured CO2 to a pipeline for industrial use and underground storage.

TRAX Carbon Capture Model Included:

—CO2 and SO2 capture
—Sulfuric acid plant
—CO2 and SO2 amines filtration and purification
—CO2 compression
—CO2 pipeline and cavern

As shown below, TRAX built a modular simulation replicating the plant layout using our software, ProTRAX.  ProTRAX contains a full suite of modules specific to carbon capture functions and can model a wide variety of processes.  TRAX also virtually replicated the user interface that appears in the plant.  

Model Scope

ProTRAX is a modular software that can easily integrate multiple models for larger projects.


TRAX organizes the simulator model to match the layout of the site or process being modeled.


Depending on the Absorber module selected, the module can remove water vapor (H2O), carbon dioxide (CO2), and/or sulfur dioxide (SO2) from an air or gas stream.


Each ProTRAX module is backed by comprehensive documentation, including a general description, module inputs and outputs, and mathematical formulae.


The training value of a simulator occurs in the interactive screens that replicate the site equipment.

Upon initial delivery, the TRAX simulator was used to debug control logic and processes prior to site installation and to provide operations training prior to plant startup.  There was a clear need to begin training operators as early as possible since they had multiple unfamiliar systems to learn.

Thanks to the ProTRAX simulator, our customer gained considerable insight into control functionality and system interactions, resulting in modification to some control logic and correction of simple errors.  TRAX was able to assist with controls tuning, and helped in development of initial plant Operating Procedures.

The latest upgrade brings the model into alignment with the as-built plant condition by updating and tuning the simulator models to match the current plant dynamics. In addition, TRAX has updated the simulator controls and HMI graphics to the as-built state.  Keeping the simulator aligned with the current plant condition is critical to maintaining a positive training value, and is of paramount importance to the customer.
