%X Une solution technique et ¨¦conomique a ¨¦t¨¦ mise au point pour traiter les pieds de bacsprovenant de la d¨¦mixtion de m¨¦langes m¨¦thanol - supercarburant au contact de traces d'eau. Le proc¨¦d¨¦ consiste ¨¤ provoquer une deuxi¨¨me d¨¦mixtion par addition d'eau ¨¤ la phase ¨¤ traiter. Les hydrocarbures ainsi relargu¨¦s sont s¨¦par¨¦s parfaitement en utilisant un coalesceur ¨¤ r¨¦sines ol¨¦ophiles. Il est ainsi possible de r¨¦cup¨¦rer et de recycler la quasi-totalit¨¦ des hydrocarbures contenus dans lespieds de bacs . L'effluent aqueux r¨¦siduel charg¨¦ en alcool peut, soit ¨ºtre recycl¨¦, soit trait¨¦ par la station de traitement d'eaux de la raffinerie. A technical and economic solution has been developed for processing bottoms of storage tankscoming from the demixing of methanol/premium-gasoline blends in contact with traces of water. The process consists in producing a second demixing by the addition of water to the phase to be processed. The hydrocarbons thus salted out are effectively separated by an oleophilic-resin coalescer. In this way almost all of the hydrocarbons contained in the bottoms of storage tankscan be recovered and recycled. The residual aqueous effluent containing alcohol can either be recycled or processed by the waste-water treatment station of the refinery.
