Emissions Control Systems

For gas turbines up to 100MW, IST is now providing solutions to help meet the increasingly stringent demands of environmental regulations. IST has the experience and knowledge to reduce your plant emissions while you continue to simply generate more profit.

With more environmental legislation, many new and existing open cycle plants will need to add emissions control systems and IST is ready to help.

Here are three simple reasons why you should consider an IST Emissions Control System for your next simple cycle installation:

Flexibility, a compact Emission Control System that matches your physical requirements …
Schedule, we have the capability and capacity to meet your schedule …
Trust, minimize your risk …


Adaptable configurations mean that an IST’s Emissions Control System can be tailored to precisely match your plant requirements:

  • Range of applications up to 100 MW gas turbines
  • Emission reduction efficiencies are fully compliant for all jurisdictions
  • Vertical gas path design requires less real estate and offers unique configurations
  • The true modular design reduces emission control system footprint by as much as 1/3 when compared to traditional units
  • Systems can be designed for emission control in dual fuel operation


IST has full fabrication facilities and the expertise to construct an emission control system quickly. With IST’s short erection schedule, your operation can be up and running fast:

  • System is designed to optimize erection hours; ducting modules are pre-assembled, catalyst frames and AIG are pre-installed in the ducting
  • Short delivery for SCR and CO equipment reduces project time
  • These features not only save time, they save money too


IST has experience, resources and an industry reputation for reliability and quality- we stand behind our products and minimize your risk:

  • IST’s project management approach ensures that the right things happen at the right times and between the right people
  • The power generation industry has come to respect IST as a leader in the delivery of quality steam generators and Emissions control systems with excellent support services
  • IST has created a dedicated business unit that is mandated to produce, deliver and install emission control systems
  • Emission control systems by IST are backed by a competitive, multi-year warranty and performance guarantee
  • IST is a part of Aecon, Canada’s largest publicly traded construction and infrastructure company

IST has the experience and expertise to supply your complete Emission Control/SCR system- everything from the gas turbine outlet expansion joint through to the outlet stack, including silencers.

Our process and capabilities for application and design include:

    • Performing a CFD for every system to select proper flow distribution device for optimal catalyst performance
    • Multi-pollutant control for NOx, CO, VOC, etc
    • Supply of both aqueous and anhydrous ammonia systems
    • Control systems, thermal stress analysis, acoustic testing, life cycle design, cost/benefit analysis
    • Full modular and semi-modular designs for gas turbines up to 100 MW
    • Competitive, multi-year warranty and performance guarantee
