How High Pressure Control Valves Optimize Carbon Capture and Storage (CCUS) Systems

Carbon capture, utilization, and storage (CCUS) is becoming a key technology in reducing industrial emissions and achieving sustainability goals. By capturing carbon dioxide (CO₂) from power plants, refineries, and industrial processes, CCUS prevents it from entering the atmosphere, where it contributes to climate change.

But capturing CO₂ is only the first step. Safely transporting, processing, and storing it requires precision-engineered equipment. That’s where high-performance control valves come in. These valves regulate CO₂ flow, pressure, and phase changes throughout the CCUS process, ensuring reliability in high-pressure, corrosive, and extreme temperature environments.

In this article, we’ll walk through:

• The role of control valves in each stage of CCUS
• The challenges of handling CO₂ at high pressures
• How Trimteck’s engineered valve solutions improve system efficiency and safety

The Role of Control Valves in CCUS

CCUS systems rely on a network of pipelines, compressors, and injection wells to move CO₂ from industrial facilities to underground storage sites. Control valves play a critical role in managing pressure, preventing leaks, and maintaining system integrity.

1. CO₂ Capture and Compression

The first step in CCUS is capturing CO₂ from flue gases using post-combustion, pre-combustion, or oxy-fuel combustion methods. Once captured, the CO₂ must be compressed into a supercritical state—a phase where it behaves like both a liquid and a gas, making it easier to transport.

• Control valves regulate the pressure and flow rate of CO₂ as it moves through capture and compression units.
• These valves must handle corrosive solvents used in absorption processes while ensuring precise pressure control.

2. CO₂ Transportation

Once compressed, CO₂ travels through high-pressure pipelines to storage or utilization sites. Maintaining stable pressure during transport is critical to prevent phase changes that could cause blockages or inefficiencies.

• Severe service control valves ensure smooth CO₂ flow while withstanding pressure fluctuations.
• Automated valve systems enable real-time pressure adjustments, reducing the risk of failures in long-distance pipelines.

3. CO₂ Injection and Storage (Sequestration)

In the final stage, CO₂ is injected into deep underground reservoirs such as depleted oil fields, saline aquifers, or geological formations. Injection requires precise pressure control to prevent leaks, maintain reservoir integrity, and ensure long-term sequestration.

• High-pressure injection valves regulate CO₂ flow rates and prevent backflow.
• Erosion-resistant materials ensure durability in high-velocity injection conditions.

Key Challenges in CCUS Valve Performance

Managing CO₂ in a CCUS system presents unique challenges that standard industrial valves aren’t built to handle.

• Extreme pressure demands: CO₂ pipelines often exceed 1,500 psi, requiring robust, high-strength valve materials.
• Corrosive exposure: Contact with water, hydrogen sulfide, and carbonic acid can degrade standard valve components.
• Temperature fluctuations: Supercritical CO₂ transitions between different temperature states, putting stress on valve materials.
• Cavitation and erosion risks: High-velocity CO₂ flows can cause severe damage to valve internals if not properly managed.

To ensure long-term reliability, CCUS valves need to be engineered with severe service capabilities and corrosion-resistant materials.

How Trimteck’s Control Valves Improve CCUS Operations

Trimteck designs engineered valve solutions that meet the unique demands of CCUS systems. Our valves are built for high-pressure environments, corrosive gases, and extreme temperature conditions, ensuring safety and efficiency at every stage of carbon capture and storage.

What Makes Our Valves CCUS-Ready?

• Severe service valve designs – Engineered for high-pressure injection, supercritical CO₂ pipelines, and corrosive gas handling.
• Corrosion-resistant materials – Options include stainless steel, Hastelloy, and other high-alloy metals to prevent material degradation.
• Custom valve trim solutions – Optimized to reduce cavitation and noise, extending valve life in high-velocity CO₂ flows.

Why Precision Control Matters

CCUS operations require tight pressure control to maintain efficiency and safety. If a valve fails or performs inconsistently, it can lead to:

• Unstable CO₂ injection rates, reducing storage efficiency
• Increased risk of leaks, impacting environmental safety and compliance
• Higher maintenance costs, due to erosion and premature wear

With Trimteck’s engineered solutions, plant operators can optimize CO₂ handling, reduce risks, and improve overall system performance.

The Future of CCUS and Trimteck’s Role

As governments push for net-zero carbon targets, CCUS adoption is accelerating worldwide. New policies and incentives for carbon reduction mean that industries must implement long-term CO₂ management solutions.
