Carbon Capture

Techniques to achieve carbon capture

Global climate change is strongly influenced by the amount of Carbon in the atmosphere. Decades of industrial and individual use of fossil fuels have increases the Carbon levels effecting the atmosphere concentration of Carbon. Carbon capture can reduce the amount of carbon being added to the growing levels. It can even be used to “clean up” the existing levels of carbon already emitted to the atmosphere.

Currently research is growing rapidly in techniques to achieve carbon capture / carbon reduction long term. Unfortunately with research we have to start from the beginning and increase efficiency with more research over time. The drive to succeed is very much a global effort with Universities, Governments and the private sector all seeing this as a great opportunity to develop more efficient solutions and discover new pioneering solutions.

Carbon Taxes have resulted in the emitters of Carbon to look for solutions to avoid hefty charges. Below are some of the common applications and how our products are helping solve them.

Carbon Capture applications and solutions

Gas Flow Control for CO₂ Capture Systems

Gas flow control is essential for maintaining absorber efficiency and preventing solvent degradation. In UK carbon capture plants, dynamic load changes demand fast-response mass flow controllers to stabilise CO₂ and flue gas streams. Accurate flow ensures optimal reaction kinetics, reduces energy waste, and supports compliance with emissions targets. Integration with SCADA systems enables real-time monitoring and automated adjustments, critical for large-scale and pilot installations.

Relevant products:

  • Alicat MC Series Mass Flow Controllers: These controllers deliver rapid response (50–100 ms) and a wide turndown ratio (10,000:1), making them ideal for variable flue gas conditions. Multi-gas capability supports CO₂, N₂, and calibration blends.
