1. An installation for recovering gaseous substances from gas flows comprising:
a first atmospheric gas-treatment (AGT) module equipped with:
an inlet conduit of the gas flows which includes at least one substance to be recovered;
a set of heat exchangers;
a compression system;
drying means;
a first gas outlet conduit for mobilizing a first outlet flow towards an atmospheric gas-separation module after a modification thereof in composition, pressure and temperature;
a second outlet conduit for mobilizing a liquid flow; and
a second inlet conduit for receiving adsorbed gases in first adsorption/desorption reactors existing in an atmospheric gas-separation (AGS) module;
at least one said AGS module equipped with:
a first gas inlet which includes at least one substance to be recovered, coming from a first outlet flow from the AGT module; which is connected to a first inlet conduit for transporting gases to the first adsorption/desorption reactors; the adsorption/desorption reactors being interconnected by respective pipes and valves adapted to support a first Pressure Swing Adsorption (PSA) adsorption/desorption process;
a first outlet conduit for mobilizing desorbed gas flow after the first PSA desorption process for the sending thereof to the AGT module in which the desorption process will be controlled by of a control system; and
a second gas outlet depleted in selected gases coming from the first adsorption/desorption reactors which perform the adsorption process; and
the control system of the installation, adapted in an operation thereof to control flows of gas so as to implement the first PSA adsorption/desorption process.
