Vertical Integrated Station

Vertical Integrated LNG Fueling Station

 

The LNG Integrated Station is an advanced LNG fueling solution that integrates the storage tank bottom valves and pump inlet valves directly at the base of the LNG storage tank. The submerged cryogenic pump is installed in close proximity to the tank, eliminating the need for a separate pump skid frame and achieving a highly compact, tank-pump integrated structure.
This innovative vertical integrated LNG fueling station system significantly optimizes space utilization while improving pumping efficiency and system reliability.

Vertical Cryogenic Storage Tank Design Advantages
The vertical LNG fueling station occupies a smaller footprint, while providing a larger liquid head height difference for the submerged LNG pump, which greatly enhances the operational performance of this core component.

Vertical cryogenic storage tank LNG fueling stations account for approximately 90% of LNG refueling stations worldwide, making this configuration the most widely applicable and proven solution in the LNG fueling industry.
High Economic and Social Benefits Through Innovation
Continuous innovation in vertical LNG integrated station equipment delivers significant economic value and operational efficiency improvements for the LNG fueling station industry.
Through optimized integration, the process area footprint has been reduced from 12 m × 8 m to 8 m × 8 m, achieving a one-third reduction in site space requirements for LNG fueling station installations.

The submerged pump sumps are arranged at the four corners of the pump skid area, forming a tangential layout relative to the vertical LNG storage tank when viewed from above.
Mounting brackets are installed on the outer wall of the cryogenic storage tank or the skid frame to facilitate submerged pump installation, maintenance, and servicing.
The EAG ambient air vaporizer (Electric Air Gas Heater) is mounted on the outer wall of the LNG storage tank, fully utilizing available skid space and ultimately achieving full integration of the LNG storage tank and pump skid system.

The vertical cryogenic storage tank and pump skid adopt a layered integrated design, with the submerged LNG pump installed beneath the storage tank. The pipeline connection between the tank and the submerged pump has been optimized from a traditional Z-shaped configuration to an L-shaped layout, significantly simplifying the LNG fueling station piping system.
This optimized pipeline design reduces system complexity and minimizes pressure losses within the LNG transfer lines, thereby enhancing the overall performance and operational efficiency of the LNG fueling station equipment.
All major systems undergo comprehensive factory pre-commissioning, including pressure testing, leak tightness testing, and functional performance testing prior to delivery. The integrated LNG storage tank and pump skid package is then shipped to the customer as a complete unit, which helps reduce on-site construction and installation time by approximately 21 days, accelerating project commissioning and lowering overall project costs.
