The column comprises within one common vessel (3): a first inlet (41) for a first liquid feed stream (51), a second inlet (42) for a second liquid feed stream (52), a first outlet (61) for a product stream (71), a second outlet (62) for a byproduct stream (72), a mixing section (8) comprising an agitation means (9), a static section (10) comprising a packing (11), optionally a collector (12) and/or distributor (13), characterized in that within the common vessel (3) are only one mixing section (8) and only either one or two static sections (10). The invention further relates to a process for using said column. The present invention further relates also to the use of the column or process in removing aromatic compounds from organic streams, in treating an oil stream of a refinery, or in a liquid-liquid extraction process.</p> |
