LNG Skid Functions

Regasification

Regasification lets you turn liquefied natural gas back into a usable gas form. You use an LNG skid to make this process fast and safe. The skid handles the cold liquid and changes it into gas for your needs.

Vaporization

You can vaporize LNG using different methods. The most common ways are shown in the table below:

Ambient vaporizers use the air outside to warm the LNG. Water bath vaporizers use hot water to speed up the process. Both methods help you get natural gas ready for use.

Regulation & Metering

Regulation and metering help you control the gas flow and measure how much gas you use. An LNG skid uses special meters, like Coriolis flowmeters, to give you real-time data. You can see exactly how much gas you get. Automated systems keep the gas pressure steady and safe. You can trust the skid to deliver the right amount of gas every time.

Liquefaction

Liquefaction lets you turn natural gas into a liquid. You use an LNG skid to cool the gas until it becomes a liquid at very low temperatures. Small-scale LNG skids can produce between 10 and 200 tons of LNG each day. Most often, you see skids making 20 to 80 tons per day. Some skids can make up to 130 tons daily. You can choose the size that fits your needs.

Liquefaction makes it easier for you to store and move natural gas. You can use the liquid for fuel or send it to other places.

Loading & Offloading

Loading and offloading help you move LNG from one place to another. You use an LNG skid to keep the LNG cold, around -162 degrees Celsius, during transfer. The skid has special valves, pumps, and insulated pipes. These parts make sure you move LNG safely and quickly.

• Automation helps you control the process with less effort.

• Safety systems protect you from accidents.
