Abstract
The apparatus proposed herein relates to mass-exchange apparatus for isolating polymers from hydrocarbon solutions. The apparatus comprises a vertical column provided with a device for producing polymer crumb and an aqueous suspension, a device for feeding live steam, and contact trays which divide the column into compartments as for height. The device for producing polymer crumb and aqueous suspension is accommodated in the top portion of the vertical column and is essentially a chamber established on at least one side by the overflow baffle. The chamber accommodates the water supply nozzle and a conventional injector-type polymer crumb former. Such an arrangement of the device for polymer crumb formation and producing aqueous suspension results in a simplified construction of the entire apparatus and diminished overall dimensions thereof, as well as to a simpler attendance of the apparatus.
