Frequently Asked Questions (FAQs)

At what maximum pressure should LNG be stored?
The LNG tank pressure limit is that which the tank is designed for. This value can be found on the mandatory nameplate of each equipment.
What regulations apply in Spain to the manufacture of static tanks for LNG?
The only mandatory guideline in the manufacture of storage tanks is the European Pressure Equipment Directive (PED 2014/68/EU). The choice of the standard or code for its design and manufacture is the responsibility of the manufacturer. For all LNG equipment that is installed in Spain, the indications of the Spanish regulations on LNG facilities must be observed.
I have a tank prepared for LNG storage. Can I store liquid nitrogen or other gases in it?
Each fluid has particular characteristics that must be taken into account. In some cases it will not be possible to store another fluid, or restrictions on the degree of filling must be taken into account. In other cases, it will be possible by making slight changes to the level measurement system.
Should I carry out a leak test on my LNG tank at the time of its installation?
According to Spanish regulations, a vacuum check is enough (it must be less than 0.6 mbar).
How often is it mandatory to check the vacuum in my cryogenic tank chamber?
Although the only mandatory inspections are those indicated in the Gas Regulations and the Pressure Equipment Regulations, it is advisable to establish a shorter periodicity to carry out this check. Each maintenance company must mark a maximum period, according to their maintenance plan.
What are the so-called economizers (in the field of a cryogenic storage tank)?
It is a circuit by which fluid is sent in the gas phase to the consumption pipe (normally the liquid phase). In this way, a rapid decrease in pressure in the tank is achieved, which can prevent the opening of safety valves. If there is no consumption, the economizer cannot perform its function.
How often is it advisable to create vacuum the isolation chamber?
There is no pre-established criterion. It is recommended to create vacuum (= reduce pressure) before reaching the value of 0.6 mbar.
