TRAX Partner Spotlight: STEAG Energy Services (India)

STEAG Energy Services (India) Pvt. Ltd. — a TRAX partner for many years — is a subsidiary of STEAG Energy Services GmbH, a German IPP. They are involved in a wide array of industries and provide valuable services such as project development, engineering, and operations and maintenance.


Recent Success. Sanjeev Kumar, STEAG GM (System Technologies), says this has been “a special kind of simulator.” For this sizeable project, STEAG used ProTRAX to model the system elements, including 13 boilers and seven associated steam turbines, desalination plant with 24 Ros, five limestone FGDs, electrical distribution, and BOP.

STEAG and TRAX have been partners for over 10 years and have worked together to develop superior service for simulator customers, first in India and now as far as Africa. STEAG independently develops simulators using the ProTRAX software platform and has amassed an impressive customer resume. Their experience includes work with traditional drum boilers, CCGT, supercritical units, solar thermal processes, and other process configurations. STEAG is currently developing 13 simulators, with several others out for delivery.


STEAG is proud to call itself “the Consultant with Operational Experience,” and TRAX is grateful to have such an exceptional partner. Our partnership is already planning new collaborations in new countries.

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.
