Abstract:
    Effluent liquors, eg. those produced on cooling synthesis gas streams obtained by the ash slagging of coal in the presence of steam and oxygen, and containing volatile and oxidizable species are purified by sparging the liquor with an oxygen-containing gas. The liquor may be sparged with steam prior to oxygen-sparging or, alternatively, a mixture of steam and oxygen may be used for the sparging. The gaseous products obtained after sparging may be used directly as reactants for the coal gasification reaction together with any supplementary steam and/or oxygen.
