    Small & Medium-Sized Natural Gas Liquefaction Plant


    Product Overview
    CRYO-TECH’s Small & Medium-Sized Natural Gas Liquefaction Plant converts raw natural gas into liquefied natural gas (LNG) through advanced pretreatment and cryogenic processes. Using the internationally recognized SMRC refrigeration technology, this plant delivers high-purity LNG with superior energy efficiency, making it ideal for off-grid energy supply, industrial fuel, and transportation applications.

    Key Features


    1. SMRC Refrigeration Process:
      • Simple flow design reduces energy consumption by 15% compared to traditional methods.
      • Strong adaptability to varying gas compositions (e.g., methane, ethane, COâ‚‚).
    2. Modular Construction:
      • Skid-mounted units minimize on-site installation time and space requirements.
      • Scalable capacity from 50,000 Nm³/day to 500,000 Nm³/day.
    3. Low Operational Costs:
      • High-efficiency heat exchangers and compressors reduce maintenance needs.
      • Automated control system ensures stable performance with minimal operator intervention.
    4. Safety Compliance:
      • Dual redundancy in critical systems (e.g., refrigeration, fire suppression).
      • Meets ISO 13623, API 620, and ASME BPVC standards.

    Process Flow


    1. Pretreatment:
      • Remove impurities (Hâ‚‚S, COâ‚‚, moisture) using amine scrubbing and molecular sieves.
    2. Liquefaction:
      • SMRC refrigeration system cools natural gas to -162°C for liquefaction.
    3. Storage:
      • Store LNG in double-wall insulated tanks with 0.1% daily evaporation rate.
    4. Distribution:
      • Load LNG into ISO tanks, trailers, or feed to downstream vaporization stations.

    Applications


    1. Industrial Fuel:
      • Replace coal/fuel oil in power generation, ceramics, and glass manufacturing.
    2. Clean Energy:
      • Gasification for urban pipeline networks and decentralized heating systems.
    3. Transportation:
      • LNG for heavy-duty trucks, buses, and marine vessels.
      • CNG refueling stations via LNG-to-CNG conversion.
