Understanding flue gas composition is key to optimizing a carbon capture system. Detailed characterization helps systems perform better and adapt to real-world conditions.

Reduce uncertainty in the design and operation of your carbon capture system with detailed flue gas characterization. This study uses a hypothetical cement plant as the project and then compares three scenarios. By comparing three scenarios, you’ll see firsthand how early and thorough flue gas characterization impacts a project. The scenarios are:

Detailed Flue Gas Characterization: The plant is designed with adequate pre-treatment, redundancy, amine reclamation equipment and operating costs are minimized.

Minimum Required Characterization with Site Optimization: The initial plant design is inadequate, and capture efficiency is low for the first two years while capital is spent on plant upgrades, eventually capture efficiency and operating costs match the detailed characterization scenario.

Minimum Required Characterization, Unmitigated: The initial plant design is inadequate, and no additional capital is spent on improvements, capture efficiency remains low and operating costs remain high for the life of the plant.

This study outlines how flue gas characterization can:

  • Reduce the levelized cost of capture.
  • Increase capture efficiency and rates.
  • Optimize system performance and efficiency from the start.
  • Reduce site downtime.

Flue Gas Insights for Reduced Capture Costs

Enter your projected capital expenditure and capture rates into the tool to map out scenarios for your flue gas pre-analysis.

This model uses a 1 million tonne per year carbon capture facility on a cement plant with a natural gas fired kiln. Contact us to request other sectors.

Projected Benefits

Based on your CapEx and CO2 numbers, we estimate that incorporating flue gas characterization and optimization will offer the following benefits compared to an unmitigated CCS facility after minimum required environmental characterization:

Levelized Cost of Capture ($/tonne CO2)
