Valves for CCUS

Proven valve solutions for CO₂ capture, utilization, and sequestration

Why choose SLB valves for CCUS?

Our broad offering of valves spans the full range of applications from CO₂ capture through processing, transportation, and eventual utilization or storage.

Low-emissions-certified portfolio

All our valves for CO₂ service have been fugitive emissions certified (FE certified) using methane (CH₄) or helium to prove their sealing capabilities, based on current certification protocols.

Prequalification of seals

CO₂ is challenging for seal materials because of swelling, rapid gas decompression damage, and the impact of low temperatures on elasticity. We have prequalified multiple seal materials to several applicable standards for different service conditions to ensure performance.

Trim selection

Depending on the level of contaminates, CO₂ can range from noncorrosive to extremely corrosive. Moreover, blowdown of CO₂ can result in very low temperatures, which affect the characteristics of materials. We offer a large range of materials and sealing technologies to match requirements.

Comprehensive offering

Beyond valves for CO₂ applications, we provide a host of auxiliary services, including digital enablement, monitoring, valve evaluation for repurposing pipelines for CO₂ service, and a suite of total valve care solutions.

CCUS: A path to mitigating carbon emissions

CO₂ is one of the greatest contributors to global warming, and capturing it is key to preventing large amounts from entering the atmosphere. It can be transported and handled in a gaseous, liquid, or supercritical (dense) phase, all necessitating special attention to valve and seal materials. Presence of contaminants can cause the fluid to vary from noncorrosive to highly corrosive and must also be taken into account. Leverage our proven products and decades of experience to address these challenges with confidence.
