Products Details
Liquefied Natural Gas (LNG)
Liquefied Natural Gas (LNG) is natural gas cooled to a liquid state for efficient storage and long-distance transportation. Its high energy density and clean-burning properties make it a key fuel for global energy markets.
Product Description
Liquefied Natural Gas (LNG) is primarily composed of methane (CH₄), with small amounts of ethane and other hydrocarbons. It is produced by cooling natural gas to approximately –162°C, reducing its volume significantly and enabling safe, non-pressurized storage and transport.
LNG is odorless, colorless, non-toxic, and non-corrosive, making it suitable for large-scale energy distribution. Before liquefaction, impurities such as water, acid gases, and heavy hydrocarbons are removed to ensure product stability and prevent damage to equipment during storage and transport.
LNG is widely used for transporting natural gas across regions where pipeline infrastructure is not feasible. Once delivered, it is regasified and distributed for industrial, commercial, and energy applications.
Key Features
High Energy Density
Offers significantly higher volumetric energy density compared to compressed natural gas (CNG), enabling efficient long-distance transport.
Clean-Burning Fuel
Lower emissions compared to conventional fossil fuels, supporting cleaner energy applications.
Efficient Storage & Transport
Liquefaction reduces gas volume substantially, making LNG suitable for marine and bulk transport.
Global Energy Utility
Widely used across power generation, industrial fuel systems, and gas distribution networks.
Technical Requirements
Storage & Handling Guidelines
- Store in specialized cryogenic tanks designed for LNG
