| abstract | <PICT:0843978/III/1> Apparatus for removing the light oil from a benzolized wash oil and for purifying the wash oil for reuse comprises means for applying water vapour to the benzolized oil to remove the benzol therefrom, means for receiving a portion of the light oil from the first named means and including steam provision means to vaporize said light oil thereby producing a mixture of light oil and water vapours, means for supplying one part of said mixture to said first named means to provide the water vapour therefor, means for removing the light oil vapour from the other part of the mixture by condensation and returning the condensate to said first means as purified light oil, and means for supplying the water vapour remaining from said other portion to said steam provision means. In a preferred embodiment benzolized wash oil which is taken from a scrubber is lead to a heat exchanger 11 and then to a heater 15 and a stripping tower 17 in which the light oil is stripped from the wash oil with the aid of live steam. A purifier 19 purifies a portion of the wash oil and supplies steam to the stripping tower, and a pump 21 circulates the debenzolized wash oil. Steam for the stripping tower 17 is first sent through purifier 19 which has an inlet 51 for receiving the wash oil to be purified, an outlet 53 for vapours, a bubble-type tray 55 for condensing the wash oil vapours, an inlet 57 for cool wash oil for the condensing of the wash oil vapours, an outlet 59 for the purified wash oil, a mist separator 60, a water vapour outlet 61 connected by way of conduit 62, and a compressing injector 63 with a steam inlet 65, an auxiliary indirect steam heating coil 67 and an outlet 69 for the withdrawal of the residue. The quantity of stripping steam required for stripping the light oil from the wash oil in tower 17 is used as the compressing fluid in injector 63. |
