Technical Requirements
 
01/

The storage tank is equipped with stainless steel cryogenic globe valve, combined vacuum valve (including vacuum gauge to measure the vacuum degree of the insulation layer at any time), safety valve, relief device, pressure gauge, liquid level gauge and other valve instruments.

02/

The inner vessel is equipped with two sets of independent over-pressure relief devices to effectively ensure the safety of the tank. In addition, the safety explosion-proof devices installed on the outer vessel further ensure the safety and reliability of the entire equipment.

03/

For the inner vessel of the storage tank, 100% Radiographic Testing (RT) is first performed on Category A and Category B welded joints. This is followed by 100% Penetrant Testing (PT) on all welded joints. After ensuring that the non-destructive testing results are qualified, a pneumatic test is conducted on the inner vessel. Finally, each weld and joint is subjected to a leak test using a helium mass spectrometer leak detector.

04/

The finished paint film on the outer surface of the storage tank is dense, firm and reliable, and the dry film thickness of the paint is greater than 200 µm.

05/

The tank needs to be replaced with nitrogen before leaving the factory. Fill the interior of the liquid container with 0.03~ 0.05Mpa pressure nitrogen gas for protection.

06/

The LNG high vacuum storage tank is easy to install and have low maintenance costs. It is mainly used in city gas supply, industry combustion gas supply and gas station, etc.

 

Oxygen Vacuum Storage Tank

 

Advantages

Tank adopts with high vacuum winding insulation design and auxiliary high efficient vacuum maintain technology, result to a good heat insulation effect and less liquid evaporation.

 

Body adopts with large diameter design,low vertical transport height,to ensure product performance,save more costs when transportation.

 

Main structure is compact,footprint is small,installation is fast and convenient.

 

The pipe layout is neat and clearly,top of the tank is designed with whole forging welding structure to prevent gas or liquid leakage which caused by thermal expansion and cold contraction.

 

Option selected flow meter, remote monitoring,can be achieve digital and information management .

 

 

LNG Storage Tanks Applications

LNG storage tanks perform multiple key functions in the energy sector:


Import/Export Terminals: Import/export terminals consist of large-scale LNG storage tanks that hold liquefied natural gas until it needs to be regasified for distribution or loaded onto ships for transportation.


Peak Shaving Facilities: Utilizes smaller LNG storage tanks to regulate variances in demand for natural gas. Operators will be able to store excess liquid natural gas (LNG) during low-demand period and release them during times of peak demand.


Bunkering Stations: Used for refueling ships powered by liquefied natural gas, bunkering stations utilize LNG storage tanks as a cleaner alternative to conventional marine fuels.


Power Generation Plants: LNG is used as a fuel source in some power plants which means they need to store LNG on-site through the help of storage tanks to maintain a steady supply of natural gas for electricity generation.


Industrial Applications: Some industries utilize LNG as a feedstock in chemical processes or as an energy source for factory systems, which calls for specific storage systems.

Ethylene Vacuum Storage Tank

 

Construction Elements of LNG Storage Tanks

This includes the layout of the LNG storage tank, distribution re-flashing, insulation technologies, floating roofs, etc. Key features include:

 
 

Insulation

Liquefied natural gas tanks are heavily insulated with materials like perlite or polyurethane foam in order to keep the partner molecules at low temperatures. This insulation reduces heat transfer from the surroundings and prevents the evaporation of the LNG.

 
 
 

Materials

The inner tank is commonly made of nickel-steel alloys, which do not tend to become brittle at extremely lower temperatures. The outer tank is made of carbon steel / reinforced concrete.

 
 
 

Auto-Refrigeration System

The auto-refrigeration system is built in many LNG tanks and they can vent boil-off gas (gas that evaporates from the liquid) to control the temperature. This system also helps keep the pressure and temperature within acceptable range.
