LAR Storage Tank
Introduction
Liquid argon storage tank is a low-temperature pressure vessel using vacuum insulation technology, specifically designed for safe and efficient storage of liquid argon gas (-186 ℃). It is a key equipment in the production, storage, transportation, and application industry chain of argon gas.

Function in air separation equipment
Storage terminal for high-purity products
Receiving and storing ultra-high purity liquid argon produced by the full distillation argon production system, which is the final export for its external sale or internal use as a commodity.
Buffer and guarantee of the production system
Balance the mismatch between the continuous argon production of the air separation equipment and the periodic or fluctuating consumption of downstream users, ensuring the stability of the operating conditions of the air separation main tower.
The direct manifestation of economic benefits
Argon is one of the most economically valuable by-products in air separation units. The configuration of the storage tank is directly related to the storage capacity, sales flexibility, and overall revenue of this high-value product.

Main advantages
High storage efficiency
The volume of liquid argon is only about 1/800 of that of gas, with a large storage capacity in a single tank, significantly saving space and costs.
Ensuring gas purity
As a liquid storage, it can effectively maintain the high purity of argon gas and prevent pollution, which is crucial for high-end applications such as semiconductors.
Stable supply
It can be used as the main or backup gas source to ensure stable supply for continuous production processes, without being affected by gas equipment maintenance or transportation interruptions.
Flexibility and economy
For users who are not close to large air separation plants, transporting and storing liquid argon through tanker trucks is often a reliable and economical way to obtain high-purity argon gas.
