LNG Skid

Share:

The company's self-developed LNG Skid (SL-DQ) is equipped with LNG pumps, pipelines, instruments, valves and vaporizers etc. all on a skid. LNG pumps are all cryogenic submersible pumps, the main pipeline, pump sump and valves are all made of stainless steel vacuum tube. The LNG Skid has the functions of filling, unloading and saturation tuning etc.

SL-DQ LNG Skid has the following features:

- Highly integrated, small footprint, small on-site installation and speed to usage;

- Skid-mounted design, easy to transport and tranfer, with good mobility;

- The electrical instrumentation system adopts explosion-proof design, which is safe and reliable;

- The process line is compact, pre-cooling time is short, and the filling speed is fast.


LNG Skid Station 

The company's self-developed SL-DQ LNG Skid is a highly integrated solution that incorporates a high-performance LNG Dispenser, along with cryogenic submersible pumps, pipelines, instruments, valves, and vaporizers, all mounted on a single skid. Key components, including the main pipeline, pump sump, and valves, are constructed from stainless steel vacuum-jacketed tubing for optimal performance. This all-in-one unit delivers multiple functions such as filling, unloading, and saturation adjustment.

Key features of the SL-DQ LNG Skid include:

  • High integration, resulting in a compact footprint, minimal on-site installation requirements, and rapid commissioning;

  • Skid-mounted design for easy transportation, relocation, and enhanced mobility;

  • Explosion-proof electrical instrumentation system, ensuring operational safety and reliability;

  • Compact process piping layout, which reduces pre-cooling time and enables fast filling speeds.

Functions & Applications

Key Functions:

  • Filling & Unloading: Efficiently transfer LNG between storage tanks and transport vehicles (like tanker trucks).

  • Saturation Tuning: Maintains the correct pressure and temperature of the LNG storage tank.

  • Distribution: Can be configured as a simple skid-mounted station for dispensing LNG to end-users.

Typical Applications:

  • Satellite LNG Stations: Ideal for small to medium-scale industrial users not connected to the pipeline grid.

  • Vehicle Refueling Stations: Serves as the core unit for LNG refueling stations for trucks and buses.

  • Peak-Shaving Plants: Provides backup fuel supply during periods of high demand.

  • Industrial Gas Supply: Used as a reliable LNG source for manufacturing processes.



Why Choose Our LNG Skid?

  • Faster Deployment: Skid-mounted design means minimal on-site work. Get your station operational in days, not weeks.

  • Enhanced Safety: Integrated safety systems and explosion-proof components ensure reliable operation in hazardous environments.

  • Reduced Loss: Excellent insulation and compact piping minimize LNG boil-off gas, saving you money.

  • Cost-Effective: Lower installation and civil work requirements lead to significant overall cost savings.
