Technical details and manufacturing context for CO₂ Storage Tank

Definition
A specialized storage tank that holds carbon dioxide in liquid or gaseous form under controlled pressure and temperature conditions, serving as a buffer and supply reservoir within a CO₂ supply system for industrial applications such as carbonation, chemical processes, or carbon capture systems.
Working Principle
Maintains CO₂ in a stable state (typically liquid under pressure) through insulation and pressure regulation, with safety valves and pressure relief systems to prevent over-pressurization, allowing controlled withdrawal for downstream use.
Common Materials
Carbon steel, Stainless steel

Application Fit & Sizing Matrix

Operational Limits
pressure: Up to 3000 psi (20.7 MPa) maximum working pressure
flow rate: Dependent on outlet configuration, typically 0-500 kg/min for liquid discharge
temperature: -40°C to +50°C (operating range for liquid CO₂ storage)
slurry concentration: Not applicable - designed for pure CO₂ storage only
Media Compatibility
✓ Food-grade CO₂ for beverage carbonation ✓ Industrial-grade CO₂ for welding applications ✓ Medical-grade CO₂ for healthcare facilities
Unsuitable: Seawater or marine environments due to corrosion risks from salt exposure
Sizing Data Required
  • Required CO₂ storage capacity (kg or tons)
  • Maximum discharge rate requirement (kg/min)
  • Available installation footprint and height constraints

Reliability & Engineering Risk Analysis

Failure Mode & Root Cause
Stress Corrosion Cracking (SCC)
Cause: Combination of tensile stress from internal pressure and corrosive environment from CO₂ impurities (e.g., moisture forming carbonic acid) in low-temperature storage conditions, particularly in welds and heat-affected zones of carbon steel tanks.
Brittle Fracture at Low Temperature
Cause: CO₂ storage at temperatures below -20°C can cause embrittlement in carbon steel materials if not properly specified (e.g., incorrect material grade like standard carbon steel instead of low-temperature carbon steel), leading to catastrophic failure under pressure or impact.
Maintenance Indicators
  • Audible hissing or whistling from pressure relief valves or fittings indicating potential CO₂ leakage or overpressure
  • Visual frost formation or ice accumulation on tank exterior (especially at welds or valves) suggesting insulation failure or internal leakage
Engineering Tips
  • Implement strict moisture control in CO₂ supply (maintain dew point below -40°C) and use continuous corrosion monitoring (e.g., ultrasonic thickness testing) at high-risk areas like welds and bottom plates
  • Ensure proper material selection (e.g., ASTM A516 Grade 70 for low-temperature service) and conduct regular non-destructive testing (NDT) including magnetic particle inspection for crack detection in stress concentration zones
