Title:
AIR SEPARATOR
Document Type and Number:
Japanese Patent JPS576282
Kind Code:
A
Abstract:
An air separating system, including: at least three impurity adsorbers connected with each other by a number of on-off and follower valves and located in air supply conduits leading from an air cooling tower for water-cooling the feed air to reversing heat exchangers of the system; an expansion turbine for producing chill necessary for the system; turbine output gas conduits for feeding part of output gas of the expansion turbine to one of the impurity adsorbers through the heat exchangers; regenerating gas conduits for feeding to another adsorber the outflow of the turbine output gas from the first adsorber after heating; and a cooling water circuit for circulating cooling water between a water cooling tower for cooling the cooling water against waste nitrogen gas to be discharged from the system through the heat exchangers and the air cooling tower; the feed air from the air cooling tower being supplied to the heat exchangers in operation through at least one of the impurity adsorbers, while discharging part of the turbine output gas through the remaining adsorbers which are connected in series by the on-off and follower valves and the regenerating gas conduits.
