Metering Function

CO₂ applications require accurate flow measurement for EOR injection monitoring, CCUS custody transfer, beverage grade distribution, and refrigeration systems. Metering skids handle liquid, gas, or supercritical CO₂ with density compensation calculating mass flow. Typical accuracy ±1-2% supports operational and commercial requirements across diverse CO₂ applications.

System Components

Complete skids include Coriolis or ultrasonic flow meters measuring mass flow directly, density transmitters for phase verification, temperature and pressure monitoring, flow computer with CO₂ property calculations, totalizer for cumulative mass, isolation and bypass valving, and control panel. Pre-assembled packages suit installation in CO₂ pipelines and distribution systems.

Meter Technology

Coriolis meters provide direct mass measurement independent of phase handling liquid, gas, or dense phase CO₂. Ultrasonic meters suit large diameter pipelines with no pressure drop. ERGIL selects technology based on CO₂ phase, flow range, operating pressure typically 800-2200 psig, and temperature conditions ensuring accurate measurement across supercritical transitions.

Applications

Enhanced oil recovery CO₂ injection metering, carbon capture transport and storage custody transfer, food grade CO₂ distribution, industrial refrigeration systems, dry ice production monitoring, and beverage carbonation supply. Serves oil and gas EOR projects, CCUS facilities, food processing, and industrial gas operations.

Phase Considerations

CO₂ exists as liquid, gas, or supercritical phase depending on pressure and temperature. Metering systems accommodate phase changes maintaining accuracy. Dense phase CO₂ at pipeline conditions requires specialized measurement. Flow computers apply appropriate property correlations ensuring correct mass calculation across operating conditions.

Control Integration

Real-time flow and density data enables injection optimization in EOR operations. Totalizers support custody transfer documentation. Alarm functions detect abnormal conditions. Integration with SCADA provides remote monitoring and emissions reporting for CCUS compliance.

Material Selection

Stainless steel construction resists CO₂ corrosion particularly with water content. Materials rated for cryogenic conditions in low-temperature applications. Design handles operating pressures to 3000 psig and temperatures -50°C to 50°C. Proper material selection prevents stress corrosion cracking.

Construction Standards

Design per ASME B31.4 or B31.8 for pipeline applications. Meter installation per manufacturer requirements. Materials suitable for CO₂ service per NACE standards. Explosion-proof electrical systems where required. Complete documentation with calibration certificates supporting custody transfer validation.

ERGIL CO₂ metering skids deliver reliable measurement for enhanced oil recovery, carbon capture operations, and industrial CO₂ applications ensuring accurate flow tracking and commercial compliance.
