Process for the removal of hydrocarbonaceous compounds from an aqueous stream and hydrogenating these compounds |
| abstract |
A process for the removal of hydrocarbonaceous compounds from an aqueous feed stream comprising less than about 1 volume percent of the hydrocarbonaceous compounds which comprises the steps of: (a) contacting the aqueous stream with an adsorbent to remove the hydrocarbonaceous compounds from the aqueous stream to provide an aqueous stream having a reduced concentration of hydrocarbonaceous compounds; (b) contacting spent adsorbent which has accumulated the hydrocarbonaceous compounds from the aqueous stream with an elution solvent to remove the hydrocarbonaceous compounds from the spent adsorbent thereby regenerating the adsorbent; (c) contacting the elution solvent in admixture with the hydrocarbonaceous compounds which were removed from the spent adsorbent in step (b) in the presence of hydrogen with a hydrogenation catalyst in a hydrotreating reaction zone; (d) contacting the hydrotreating reaction zone effluent with an aqueous scrubbing solution; and (e) introducing a resulting admixture of the reaction zone effluent and the aqueous scrubbing solution into a separation zone to provide a hydrotreated elution solvent and a spent aqueous stream having a volume of less than about 4% of the aqueous feed stream. |
