LNG Engineering

Liquefied natural gas is widely used as clean energy. And for it, Jereh owns a variety of self-developed natural gas liquefaction technologies, such as mixed refrigerant cycle and expander refrigeration cycle. Depending on the different cooling principle and working condition, Jereh develops optimized single stage mixed refrigeration (SMR), C3 pre-cooled mixed refrigeration (C3MR) and double mixed refrigeration (DMR) for different needs.

Single-stage Mixed Refrigeration Cycle (SMR)

Technical Features

  • Simple process and easy commissioning
  • Low one-time investment
  • Less equipment and area coverage
  • Suitable for small and medium-size LNG plant


Propane Pre-cooled Mixed Refrigeration Cycle (PRECOOLED MR)

Technical Features

  • Low energy consumption in liquefaction and operation cost
  • Simple mixed refrigerant components, easy ratio adjustment
  • Suitable for medium and large-size LNG plant


Skid-mounted LNG plant


Stationary LNG plant
