Defining the New Generation of Liquefaction Plants

Chart defined small-scale LNG through a range of standard plants with capacities ranging from 3,000 gallons per day (10 tons per day) to 450,000 gallons per day (725 tons per day). Each plant is a complete packaged solution required to liquefy natural gas. Chart’s mid-scale modular model challenges the traditional paradigm that a large baseload LNG facility provides the best economy of scale.

Modular Mid-Scale LNG Liquefaction

In contrast to the risk profile and upward CAPEX of a traditional baseload liquefaction plant, Chart's mid-scale solutions use multiple, smaller modular LNG trains that allow clients to scale projects according to market conditions and expand capacity as demand grows. Modular solutions are quicker to market and thereby generate faster revenues for stakeholders.

IPSMR® Process Technology

Chart’s IPSMR® process technology provides significantly better efficiency and superior performance over other comparable technologies and makes it possible to optimize liquefaction systems over a wide range of site conditions. IPSMR® process technology can be configured to match available gas turbine power with single cold box capacity to >4 MMTPA.

Efficient Heat Exchange is Key

Brazed aluminum heat exchangers provide optimal thermal performance and operating efficiency versus other heat exchanger types and are at the heart of our standard and modular plant solutions and process technologies.

LNG Liquefaction Plants

Features and characteristics of Chart liquefaction plants, all the way from micro- to modular mid-scale.


Biogas Liquefaction

Commercially viable solution for the liquefaction of smaller gas volumes typically associated with biogas. Chart's C15MR Micro LNG liquefaction plant enables customers to recover and monetize methane produced during anaerobic digestion processes.

BioLNG is defined as the highly sustainable version of LNG, has virtually identical chemical properties and can be used at source for power generation, natural gas vehicle fueling, bunkering, loaded into cryogenic containers and transported for regional use or vaporized and injected into the pipeline.

Biogas liquefaction plant

Plant features include:

  • Nameplate capacity of 15,000 gallons per day (25 tons per day)
  • Shop built and tested equipment
  • IPSMR process technology
  • Skid mounted for over the road shipping and easy site install

Floating LNG (FLNG)

FLNG refers to the process of developing offshore, or near shore, natural gas reserves using a floating facility that incorporates raw gas processing, liquefaction and storage. The floating units can be platforms or converted ships/barges, the latter typically slated for small- and mid-scale FLNG projects.

As with all offshore projects, minimized footprint, modularization and reliable equipment performance in a harsh environment are all pre-requisites, hence why Chart critical cryogenic and rotating equipment has a proven pedigree in many FLNG projects, including, reportedly, the first floating vessel to produce LNG in 2016.

Chart FLNG equipment scope includes:

  • Brazed aluminum heat exchangers (BAHX)and cold boxes - heavy hydrocarbon removal can be incorporated into the design providing further process integration
  • Mixed refrigerant compression loop
  • Cryogenic storage tanks
  • Vacuum insulated pipework (VIP)
  • Screw compressors
  • Steam turbines
  • Turbo blowers

IPSMR® Process Technology

Chart's IPSMR process technology, proprietary brazed aluminum heat exchangers and cold boxes are the key to right-sizing mid-scale LNG.

Interesting Facts


of carbon dioxide emissions saved

Since 2014 Gaslink has been using a fleet of Chart ISO containers to transport LNG to the gas fired power station on the island of Madeira.

More than 10,000 deliveries of clean burning natural gas have prevented 270,000 tons of CO2 being emitted into the atmosphere as well as > 3,000 tons of SOx, > 12,000 tons of NOx and > 150 tons of particulates.
