The invention primarily concerns a facility for storing and cooling a liquefied gas, for example a liquefied natural gas, the facility comprising at least one tank configured to contain the liquefied gas, a closed cooling circuit configured to be supplied with liquefied gas in the liquid state coming from the tank, at least one injection member configured for reinjecting cooled liquefied gas into the tank, the facility being characterized in that it comprises at least one connection line configured to recover a cooled gas from at least one remote container that is separate and independent from the facility.

Disclosed is a cartridge for storing pressurized gas, including a main body with an internal volume for storing a gaseous mixture NO/N.sub.2, and a distribution valve for controlling the output of the gas. The internal volume of the main body is less than 1000 ml. The concentration of NO in the gaseous mixture NO/N.sub.2 is between 15000 and 25000 ppmv. The gas pressure in the internal volume is below 15 bar, measured at 23° C. Installation for delivering gas to a patient, including such a gas cartridge, a NO supply device fed by the gas cartridge, and a medical ventilator feeding a patient circuit which has an inhalation branch fed by the NO supply device. Use for treating patients suffering from pulmonary hypertension or hypoxia.

The invention relates to a method for providing pressurized gas from a source of liquefied gas to a consumer (8), wherein vaporized gas is supplied from the source of liquefied gas (1) through a main input line (2) to a compressor arrangement (300) for pressurizing the vaporized gas, the compressor arrangement (300) comprising a plurality of compressor modules (3, 5, 31, 51), each compressor module being able to operate independently from any other compressor module of the compressor arrangement (300), one or more of the compressor modules (5, 51) of the compressor arrangement (300) can be bypassed, and wherein gas is conducted through only a part or all of the compressor modules depending on at least one of pressure level, temperature level, mass flow and composition of the gas to be provided to the consumer (8).

The method for producing a filled container of the present invention includes: providing a metal storage container, at least an inner surface of which is formed of a manganese steel and in which the inner surface has a surface roughness R.sub.max of 10 μm or less; performing fluorination by bringing the inner surface of the storage container into contact with a gas containing at least one first fluorine-containing gas selected from the group consisting of ClF.sub.3, IF.sub.7, BrF.sub.5, F.sub.2, and WF.sub.6 at 50° C. or lower; purging the inside of the storage container with an inert gas; and filling the inside of the storage container with at least one second fluorine-containing gas selected from the group consisting of ClF.sub.3, IF.sub.7, BrF.sub.5, F.sub.2, and WF.sub.6.

A compressed gas energy storage system may include an accumulator for containing a layer of compressed gas atop a layer of liquid. A gas conduit may have an upper end in communication with a gas compressor/expander subsystem and a lower end in communication with accumulator interior for conveying compressed gas into the compressed gas layer of the accumulator when in use. A shaft may have an interior for containing a quantity of a liquid and may be fluidly connectable to a liquid source/sink via a liquid supply conduit. A partition may cover may separate the accumulator interior from the shaft interior. An internal accumulator force may act on the inner surface of the partition and the liquid within the shaft may exert an external counter force on the outer surface of the partition, whereby a net force acting on the partition is less than the accumulator force.
