LNG Systems


Small scale LNG plants are playing a significant role in meeting the global demand for natural gas, and they are only increasing in importance with each passing day. These plants have low maintenance and operational costs with high levels of efficiency.

As an industry leader in small to medium scale LNG liquefaction technology and processes, Nikkiso Cosmodyne’s SSLNG plants provide pure, high quality liquid natural gas  We offer both closed-loop and open-loop liquifiers depending on your needs, all of which are modular and can be customized to fit your exact requirements.Our small scale LNG liquefaction systems are built using high quality, readily available parts to ensure that each plant operates at peak efficiency, exhibiting durability, longevity, and reliability. We offer two distinct series’ of SSLNG plants: the efficient, self -refrigerated closed-loop LINEX Series liquefiers and the simple, cost-effective liquid nitrogen-assist open-loop LINEX-OL Series. To complement our SSLNG plants, we also offer the LINEX BOG liquefier, a system designed to reliquefy boil-off gas generated from any storage tank containing LNG or other cryogenic liquids.

Pure LNG in Every Scenario

Thanks to our experience in hydrocarbon separation, we can produce LNG at most any quality that is required.  Regardless of your technical requirements, our small scale LNG plants give you access to reliable parts and an extensive array of customization options and controls. We offer support and assistance throughout the installation process, and we are always available for onsite maintenance or remote assistance.

Features & Benefits

  • Designed for either stationary single site applications or as portable systems to be transported from site to site on trailers, skids, or other mobile methods
  • Combination systems are available utilizing, ambient air during warm weather and gas fired, indirect or steam heated vaporization during cold weather.
  • Because natural drafts AAVs do not have any moving parts, reliability is maximized with zero maintenance
  • process emits no CO2 or other harmful emissions unlike conventional systems
  • AAVs offer a great solution to tap into a free source of energy without any harmful byproducts
  • For larger flow rates forced draft units are available (FAVs) and the forced convection heat transfer also assists in cold air dispersion maintaining process efficiency and minimizing ground area for the installation


Natural Gas applications include well service equipment, fuel supply for remote power generation, on and off road vehicle fueling, vessel pressure building, and send out stations for terminal regasification.

Other send out applications include peak shaving for plants, temporary gas pipeline supply in the event of emergency or scheduled shutdowns, or other process applications for continuous or temporary service.

  • Bulk transfer
  • Peak shaving
  • Virtual pipeline



  • Can utilize energy from diesel, propane, natural gas, ambient air, electricity, water, engine coolant, or steam
  • Ambient vaporizers utilize direct heat and mass transfer from heat available in the atmosphere with the most efficient technology in the industry
