Specialty LNG is an ultra-high-purity, performance-engineered form of Liquefied Natural Gas designed for applications that demand precise combustion behavior, consistent thermal output, and exceptionally low emissions.
Unlike standard fuel-grade LNG, Specialty LNG is produced using advanced gas treatment, fractionation, and composition control technologies to achieve tightly controlled methane content and minimal trace impurities.
The purified natural gas is cryogenically liquefied at approximately –162°C, converting it into a clear, odorless, non-toxic, and energy-dense liquid suitable for high-efficiency industrial, power, and commercial applications.
Composition & Quality Control
Specialty LNG features a tightly controlled molecular composition to ensure predictable and repeatable combustion.
Methane (CH₄): 90–99%
Ethane (C₂H₆): Controlled trace levels
Propane & heavier hydrocarbons: <1%
Nitrogen (N₂): <1%
Carbon dioxide (CO₂): <20 ppm
Moisture (H₂O): <1 ppm
Sulfur compounds (H₂S, mercaptans): <1 ppm
This strict quality regime prevents flame instability, protects equipment, and ensures emissions compliance.
Key Characteristics
High-Purity Methane Content
Provides clean flame characteristics, stable ignition, and uniform heat release for precision systems.
Low-Emission Fuel
Up to 50% lower CO₂ emissions than coal, negligible SOx, very low NOx, and zero ash or particulates.
High Energy Density
Energy content of 50–55 MJ/kg reduces fuel handling and storage volume.
Cryogenic Storage Stability
Maintains physical and chemical stability with controlled boil-off and predictable vaporization.
Consistent Combustion Performance
Uniform Methane Number and Wobbe Index enable automated and repeatable operations.
Safe & Non-Corrosive
Non-toxic, non-corrosive, and compatible with modern cryogenic infrastructure.

Storage, Handling & Safety
Stored in vacuum-insulated cryogenic tanks with pressure relief, boil-off gas management, continuous monitoring, gas detection, and emergency shutdown systems.
LNG is non-flammable in liquid form and only ignites when vaporized and mixed with air within specific limits.
