LNG Skid Systems

LNG Skid Systems

LNG processing units mounted on skids for quicker installation and startup.
LNG skid systems, also known as LNG skid-mounted devices, are modular, transportable units designed for various processes related to liquefied natural gas (LNG). These systems are essential for efficient, safe, and reliable LNG handling, storage, and distribution. As the demand grows for cleaner fuels, liquefying natural gas proves crucial for harnessing the world’s fastest-growing energy source. DSW offers modular LNG pretreatment systems to remove impurities upstream, improving plant efficiency and ensuring the gas meets specifications.

What Is An LNG Skid?

An LNG skid, or modular LNG, consists of pre-assembled, standardised equipment mounted on a steel frame or skid. These units are designed to be easily transported and installed, providing a flexible and scalable solution for various LNG applications. The modular nature of LNG skid systems allows them to be customized and integrated into more extensive LNG infrastructure or used as standalone units for specific tasks.

Key Features of LNG Skids

1. Modularity: LNG skids are pre-assembled and mounted on a steel frame, making them easy to transport and install. Their modular nature allows them to be customised and scaled to meet specific needs.
2. Integration: These skids can be integrated into more extensive LNG infrastructure or used as standalone units, providing flexibility in their application.
3. Efficiency: LNG skids streamline operations by combining multiple functions into a single unit, reducing the need for extensive infrastructure and minimizing installation time.
4. Safety: LNG skids are equipped with advanced safety features such as pressure relief valves, leak detection systems, and emergency shutdown systems, which ensure the safe handling and processing of LNG.

Critical Components of Modular lng

1. Frame or Skid: The structural base that supports all the mounted equipment, ensuring stability and ease of transport.
2. Piping and Valves: Essential for directing the flow of LNG and controlling its movement within the system.
3. Pumps: Used for transferring LNG from one location to another, such as from storage tanks to transport vehicles.
4. Meters: Instruments that measure the flow rate of LNG, ensuring accurate measurement for billing and operational control.
5. Heat Exchangers: Devices that transfer heat to or from LNG, used in processes like vaporization or liquefaction.
6. Control Systems: Automated systems that monitor and regulate the operation of the skid, ensuring safety and efficiency.
7. Safety Features: Including pressure relief valves, leak detection systems, and emergency shutdown systems to ensure safe operation.
