LNG Storage Tanks

LNG Storage Tank

LNG needs to be stored at temperatures around -162°C (-260°F).
The vacuum insulation helps minimise heat ingress, thereby reducing the amount of LNG that boils off and ensuring efficient storage.
Vacuum LNG tanks are designed to handle the pressure changes that occur due to the vaporization of LNG.

LNG Cryogenic Tanks – Liquid Natural Gas Storage Solutions

Optimizing Efficiency and Safety with Reliable LNG Storage
DSW has been providing LNG cryogenic tanks for liquefied natural gases since 2004.
Since then, DSW has sold over 2,000 LNG tanks with the highest-quality standard designs and individual solutions tailored to customer requirements.
DSW’s Vacuum LNG tanks have capacities ranging from 3,000 to more than 100,000 and feature standard operating pressures of 18 bar, 22 bar, or 36 bar, respectively.

LNG Tanks

Unparalleled Storage Capacity and Performance

Diverse Tank Options: We offer a wide selection of LNG storage tanks, ranging from 89m³ to 1225m³, available in horizontal and vertical configurations to suit your specific needs and site constraints.
Outstanding Thermal Efficiency: Our tanks feature a lightweight stainless-steel inner vessel encased in a robust outer jacket. Combined with superior vacuum insulation technology, this design minimizes heat transfer, ensuring extended LNG hold times and minimal product loss.

The DSW Plant is certified according to:
– AN ISO 9001/2000
– ASME (U, U2, R-Stamp)
– Manufacture license of special equipment
People’s Republic of China and others

The Pressure Equipment Directive EU 97/23/EC and EN 13458 manufacture and test the pressure vessels.
These codes are internationally accepted. Consequently, installing and using these tanks in and outside China will be much easier than before.

The Cryogenic Tank temporarily stores cryogenic liquefied gases under pressure. The inner vessels are made of austenitic stainless steel and cold-stretched for selected medium/high-pressure models. These tanks are also available vertically or horizontally and can be used for LIN, LOX, LAR, LNG, CO2, and N2O.
