Abstract
1,011,569. Cold separation of gas mixtures. PETROCARBON DEVELOPMENTS Ltd. May 7, 1964 [Feb. 8, 1963], No. 5215/63. Heading F4P. Oxygen-free argon is freed of contaminant nitrogen or of a mixture of nitrogen and hydrogen by separation in a column 4 after the feed gas mixture has been at least partly liquefied by indirect heat exchange at 2 with a gaseous refrigerant, e.g. nitrogen, having been compressed at 6 and expanded without liquefaction at a turbine 9. The so-liquefied mixture then traverses a reboiler 3 and is expanded at a valve 12 into the column from the base of which liquid argon is withdrawn and after expansion at 13 is passed through a reflux condenser 5 and an exchanger 1 where it is assisted by overhead nitrogen to cool incoming feed mixture. The refrigerant performs a closed cycle and the amount fed to the turbine 9 is controlled by a by-passed valve responsive to the level of liquid argon at the base of column 4. A pressure indicating controller 14 maintains the column pressure constant, a similar controller 15 maintains constant the pressure gradient between the column and the vaporizing liquid argon but is overridden by a flow indicating controller 16 when maximum plant capacity is reached. A flow controller 17 maintains constant the overhead nitrogen flow.
