Large Atmospheric Pressure Cryogenic Liquid Storage Tank

Flat bottom tanks are storage structures that present a round cylinder shape and a flat base. These systems can help preserve and store a wide array of substances and can thus be fabricated to specifically meet each substance and business needs. It represent an efficient storage system for a number of substances, including cryogenics and liquefied gases. As more and more businesses and industries are dependent on optimal storage of substances in order to have immediate access to them, flat bottom tanks are increasingly demanded.

This type of storage tank has the basic construction of ordinary dome roof tanks. The outer surface of shell and its adjoining area is insulated against heat leak and humidity penetration with polyurethane foam, foamglas or similar materials. This unit can be used to store liquefied gases such as butane and ammonia, which have a relatively high critical temperature.
 

Double Containment Storage Tank:

Basic structure is same on the below. This type of tank is suitable for the low temperature storage product such as LNG, and Ethylene.
 

Full Containment

A full containment tank design is defined as a double tank designed and constructed so that both the inner tank and the outer tank are capable of independently containing the refrigerated liquid stored. The inner tank contains the refrigerated liquid under normal operating conditions. The outer roof is supported by the outer tank. The outer tank is intended to be capable of both containing the refrigerated liquid and controlled venting of the vapour resulting from a product leakage after a credible event. A full containment tank may be referred to as a full integrity LNG container.

                             Flat bottom cryogenic tank's advantages

                              Spherical Type Tank

Spherical shaped storage are used in gas and liquid storage in many industries including midstream, downstream, petrochemical,chemical, waste water, and aerospace. Spheres can store many products such as anhydrous ammonia, LPG, NGL, gasoline, naphtha,butadiene, ethylene, hydrogen, oxygen, nitrogen, argon, LNG, biogas, sewage gas and waste water.
A spherical shape offers uniform stress distribution under internal loading resulting in highly efficient pressurized storage. Sphere storage results in the lowest land space for pressurized storage and offers lower costs for foundations, coatings, accessories, and piping than other options.

WOBO Group is currently a reference for the design, tailored manufacturing, commissioning, and maintenance of cryogenic equipment and installations.
We serve the world's largest industrial gas companies and work closely with them as technological partners.
The versatility of our professional teams results in innovative procedures that are adapted to the characteristics of our clients' projects, always seeking to optimize the processes and reduce the execution times.
