ProTRAX Improvement ‒ Status Window

Graphical user interface, text, emailDescription automatically generated

The Status Window is meant to be the user’s central location for checking the status of all simulator components, including models, interfaces, and initial conditions. It collects and interprets numerous files to make viewing, navigating, and understanding the simulator’s status easier.

The Status Window consists of three main collections…

Statuses: the state of sub controllers, TCP/IP connections, licenses, or anything that is persistent

Events: includes RTEXEC commands such as a RUN, FREEZE, or LOAD

Logs: these are similar to traditional log statements in mon or log files and can also be associated with a Status or Event


  • Filtering based on labels and priorities (e.g., display debug messages or show only errors and warnings)
  • Progress indicators for long-running statuses or events, such as LOADAV
  • Filter logs via a search box
  • Error notification when the Status Window is configured to bring itself into the foreground on an error or warning
  • Configure and sort columns to show/hide, re-order, and sort columns
  • Anytime use in running or shut down simulators

ProTRAX Improvement ‒ Status Window

November 22, 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.
