Patent GB-833588-A (GB)
Title: Improvements in the recovery of gaseous initial materials of organic chemical reactions from the waste gas
IPC: B01D53/14
Filed: 1957-09-04
Abstract: <PICT:0833588/IV (b)/1> Gaseous or vaporous initial reaction materials of organic nature are returned to a reaction chamber after separation from a waste gas which comprises at least one vaporous substance of greater solubility and one vaporous substance of smaller solubility in a selective solvent.  The process of separation comprises treating the gaseous mixture in a first absorption zone with an amount of selective solvent sufficient for absorption of the readily soluble component and further treating a part of the residual gas mixture thereby remaining undissolved from the gaseous initial materials of medium solubility in a second absorbent zone by washing out with the same solvent under the same conditions; introducing the solvent thus ladened into the first absorption zone and returning the other part of the gases not dissolved in the first absorption zone to the reaction zone.  The reactions exemplified are the alkation of amines by treating olefines and the production of alcohols from olefines, carbon monoxide and water.  Specifically exemplified is the production of butanol, propanol, mono-, di- and tripropylamine. The waste gas is withdrawn from a reaction chamber 1 through pipes 2 mixed with gas from column 13 and brought to a predetermined pressure by compressor 3.  The two gases are fed to column 5 through which flows a calculated amount of selective solvent supplied through pipe 7 and pipe 8.  A portion of this gas is returned through pipe 9 to the reaction chamber 1 while at the top of column 5 there is withdrawn and vented to the atmosphere the useless gases.  The washing water flows through pipe 11 to pressure release valve 12 and into exchange column 13 maintained at a lower pressure.  At the lower end of this column is supplied fresh reaction material by pipe 15; combined through pipe 16 with the gas mixture coming through pipe 2 from the reaction chamber and supplied again to the washing tower 5 through compressor 3.  The washing water flows from column 13 into a decompression chamber 19 in which it is partly gassed-out under a lower pressure and the returned gas thus set free is supplied through pipe 20 to a compressor 14 for return to chamber 13.  The water leaves the degasser 19 through pipe 21 and valve 22 with very little reaction product and can be discarded.  Another embodiment which is shown by dotted lines in the Figure allows the water to be returned to the washing tower 5 after regeneration in a second degasser 23 under atmospheric pressure.
