ABSTRACT:
Dissolved organic compounds in waste water resulting from coal degassing or gasification processes are removed by extraction with a solvent which is substantially water-immiscible, the solvent residues in the waste water are removed by inert gas scrubbing, and CO.sub.2, H.sub.2 S and NH.sub.3 in the waste water are removed by heating and steam contacting. NH.sub.3 is effectively removed in a steam gas/liquid contacting column by feeding the condensed head product of the column back to the top portion thereof, withdrawing a portion of the condensate from the column at a level intermediate the top and bottom portions of the column, treating the condensate in admixture with waste water containing CO.sub.2, H.sub.2 S and NH.sub.3 in a deacidification gas/liquid contacting column, and feeding the sump product of the deacidification column to the first column at a region below the region at which the condensate is withdrawn but intermediate the top and bottom portions of the NH.sub.3 -removal column.
