<p>972,193. Cold separation of gas mixtures. PHILIPS GLOEILAMPENFABRIEKEN N.V. May 3, 1961, [May 6, 1960], No. 16031/61. Heading F4P. Readily condensible components e.g. water vapour and carbon dioxide are separated from a gas mixture e.g. air prior to liquefaction or separation, by passing the mixture through one or other of switchable chambers 1, 2 having valved inlets 18, 19, valved outlets 30, 31 and ice-collecting perforated partitions 3, 4 connected by fins 5, 6 to liquid gas reservoirs 7, 8 and the chambers 1, 2 are arranged in series through valved conduits 24, 25 for a short time after a switchover with the regenerated chamber e.g. chamber 2 upstream of the loaded chamber 1 until such time as a layer of ice 17 forms on the screen 4 of the regenerated chamber 2. The feed gas flow is then confined to the relatively ice-free chamber by closing a valve 29 in conduit 24 whilst liquefied gas is run off from reservoir 7 of chamber 1 which is then thawed out. Specification 885,482 is referred to.</p> |
