Installation for the distillation of air

Air distillation installation, comprising:

• (A) air compressor means having an output connected to an outlet coupling;
• (B) two cylinders for the purification of air by adsorption having inlet/outlet couplings;
• (C) an air distillation column provided with a plurality of couplings for the inlet and outlet of fluids;
• (D) a framework in which are mounted elements of the installation other than said air distillation column, with connection conduits provided with couplings for the connection to other portions of the installation;
• and
• (E) tubes for connection between said couplings of (A) to (D).

Air distillation installation comprising six modules as follows:

• (A) air compressor means having an output connected to an outlet coupling;
• (B.sub.1) a first cylinder for the purification of air by adsorption having inlet and outlet couplings;
• (B.sub.2) a second cylinder for the purification of air by adsorption having inlet and outlet couplings;
• (C) a first framework in which are mounted (a) means for precooling air;
• (b) valves and a regeneration gas reheater;
• and (c) connection conduits for interconnecting (a) and (b), these conduits terminating in couplings for connection to other portions of the installation;
• (D) a second framework in which are mounted (d) heat exchangers and subcoolers;
• (e) cryogenic valves and a cryogenic pump and an expansion turbine;
• and (f) conduits for connecting (d) and (e) and (f) and terminating in couplings for connection to other portions of the installation;
• (E) an air distillation column provided with a plurality of couplings for the inlet and outlet of fluids;
