The invention relates to a security device forming a pressurized gas release valve, said device including a body that defines a gas flow channel extending between a first upstream end, to be placed in contact with a source of pressurized gas, and a second downstream end, to be placed in contact with the outer atmosphere, the device including a stopper that is located on the channel so as to prevent the flow of the gas between the upstream end and the downstream end in a normal situation, the stopper being fusible and/or frangible so as to release the gas passage in the event of a dangerous situation when a pressure and/or a temperature exceeds a predetermined threshold. Said device is characterized in that said device includes a tank of an unstable, exothermically decomposable gas that is placed in communication with the pressurized gas released during the melting/breaking of the stopper.

Security device and container provided with such device

A method for the purification of a feed gas stream containing at least COand at least one impurity with by the incorporation of a purification step, enabling water to be at least partially removed is provided.

[object Object]

A method for the purification of a feed gas stream containing COand water and at least one impurity chosen from NOx and SOx, comprising the incorporation of a purification step for the preferential elimination of water is provided.

The invention relates to a method for the deoxygenation in a chemical loop of smokes resulting from oxidation-combustion reactions, that comprises: a first step during which the smokes are stripped from their oxygen by trapping the same by the oxidation of an oxygen-carrier material, thus producing a main flow of smokes with a reduced oxygen content; and a second step for also producing smokes that can join the main smoke flow and during which the material oxidized during the first step is reduced and regenerated by reaction with the fuel in order to be used again during said step. The invention also relates to an apparatus for implementing said method.

Method for deoxygenation of smokes and equipment for implementing same

The invention relates to a method for purifying or separating a supply gas flow containing at least one impurity, in which: a) said supply gas flow is contacted with a first adsorbent for the adsorption-removal of at least one said impurity; b) recovering said purified or separated gas; c) heating a regeneration gas containing at least hydrogen (H) and carbon monoxide (CO) using a heater having a skin temperature (T) of between 150&#xb0; C. and 200&#xb0; C. during the gas heating phase; and d) periodically regenerating the adsorbent of step a) with the regeneration gas heated during step c) at a regeneration temperature (T) such that: T=T&#x2212;&#x394;T with 5&#xb0; C.&#x3c;&#x394;T&#x3c;50&#xb0; C.
