Definitions

  • the cooled air flows at atmospheric or substantially atmospheric pressure through the space 7 to the gasfractionating column where the air is divided into fractions.
  • the boiler contains a liquid quantity of the fraction having the higher boiling point, for example oxygen, which is vaporized by the heat supplied through the carrier 14.
  • the vaporized oxygen is replenished by the liquid rich in oxygen descending from the column into the tube 10.
  • a part of the vaporizing oxygen is supplied through the tube 9 to the column.
  • a further part is removed from the boiler through the tube 13, the support 14 and the pipe 23.
  • a gas separating apparatus comprising a fractionating column having an insulating outer jacket and including a boiler, a cold-gas refrigerator for withdrawing heat from said gas separating apparatus including a freezer and a condensor surrounding said freezer, means ma ntaining a sub-atmospheric pressure in said condensor ncluding a first outlet for condensed fluid provided wlth a liquid lock therein, a second outlet for condensed fluid connected to said column, and an inlet for said column wherein a gas mixture to be fractionated is drawn into said column at substantially atmospheric pressure due to the presence of sub-atmospheric pressure in said condensor, a tube in said boiler for expelling at least part of the vapor present in said boiler, means provided between the boiler and part of said column for causing a flow resistance to the rising vapors in said boiler whereby a pressure is built up in said boiler sufficient to expel said part of the vapor through said tube.
  • aconduit extending through said wall and extending below the liquid level in said boiler.
