Wellhead Gas / Industrial Gas CO₂ Extraction & Liquefaction Plant

Beschreibung

I. Core Basic Parameters (Standard Version for Bidding & Brochures)

1. Feed Gas

  • Feed: Natural gas wellhead gas, oilfield associated gas, coal chemical / fertilizer / steel / cement plant off-gas, biogas, etc.
  • CO₂ concentration: 5% ~ 98% (wide adaptability)
  • Pre-treatment: Dust removal, dehydration, de-heavy hydrocarbon, desulfurization, demercuration
  • CO₂ enrichment: Membrane separation + PSA/VPSA or cryogenic distillation
  • Liquefaction: Compression + drying + cryogenic liquefaction
  • Product: Liquid CO₂
  • Product purity: 99.5% ~ 99.999% (food grade / industrial grade / welding grade / EOR grade)
  • Liquefaction pressure: 1.8 ~ 2.2 MPa
  • Liquefaction temperature: -20°C ~ -30°C
  • Power consumption: 180 ~ 320 kWh/ton CO₂ (depends on feed concentration and capacity)
  • Capacity:
  • Skid-mounted small unit: 0.5 ~ 5 TPH
  • Medium unit: 5 ~ 20 TPH
  • Large unit: 20 ~ 100 TPH
  • Storage & transportation: Low-temperature atmospheric storage tank / tanker / cylinder
  • Control: DCS + PLC, remote monitoring, unattended operation

4. Typical Applications

  • Enhanced Oil Recovery (EOR)
  • Food-grade carbonated drinks, dry ice, welding shielding gas
  • Carbon Capture, Utilization and Storage (CCUS/CCS)
  • Greenhouse fertilization, supercritical extraction, polyurethane foaming

1. Europe

Key words: Carbon tax, compliance, CCS/CCUS, emission reduction

  • Meets EU ETS and CBAM requirements, directly reducing carbon costs and penalties
  • Supports mandatory emission reduction in steel, cement, fertilizer and power plants
  • Decarbonized well gas can be fed into pipeline grid with higher heating value
  • Liquid CO₂ for food, dry ice, welding and agriculture with high added value
  • Aligns with EU 2030 55% emission reduction and 2050 carbon neutrality goals
  • North America
  • On-site decarbonization for shale gas wells to improve gas quality and price
  • CO₂ EOR to increase oil production + carbon credits
  • High benefit from US 45Q Carbon Capture Tax Credit
  • Mature markets for food, cold chain, welding and carbonated drinks
  • Latin America
  • Stable demand for CO₂ in greenhouse, food processing and mining
  • Skid-mounted decarbonization + liquefaction for remote oilfields without pipeline

3. Southeast Asia

Key words: Industrial growth, food & beverage, agriculture, high CO₂ price

  • Booming beverage, beer and carbonated water market with shortage of food-grade CO₂
  • Strong demand in aquaculture aeration and greenhouse fertilization
  • Recoverable tail gas from oil & gas, petrochemical and palm oil industries
  • Centralized liquid CO₂ supply for industrial parks
  • Small skid-mounted units preferred: low investment, fast payback
  • Abundant associated gas with high CO₂ content, high economic benefit
  • Large-scale EOR is mainstream demand in oilfields
  • CCUS becomes standard upgrade for carbon neutrality targets
  • Export-oriented liquid CO₂ base for Europe and Africa
  • Designed for high temperature, sand and drought; modular and fast construction

5. Africa

Key words: Resource monetization, weak infrastructure, food & mining, export

  • Low-cost feed gas from previously flared associated gas
  • Skid-mounted, compact and mobile for areas with weak infrastructure
  • Large gap and high profit for CO₂ in food, beer, fishery and mining
  • Preferred low-carbon CO₂ source for Europe with carbon premium
  • Supports local industrialization with government and international financing
  • Convert wellhead/industrial off-gas into high-value products: emission reduction + revenue increase
  • Skid-mounted/modular design: fast construction, small footprint, movable
  • High purity, low energy consumption; supports food/industrial/EOR grade in one system
  • Fully compliant with global carbon policies: carbon tax, subsidy, trading, ESG
  • Fully automatic, unattended operation, low O&M cost
