Abstract

A procedure for separating soot from an aqueous suspension of soot by adding a water-immiscible auxiliary liquid to the suspension and separating an aqueous phase that is practically free of soot, in which process, in a mixing step, the aqueous suspension of soot is contacted with the auxiliary liquid at the same time as it is vigorously stirred in order to form a dispersion in water of soot agglomerates and auxiliary liquid, after which, in a separation step, the dispersion Aqueous agglomerates are brought into contact with a stationary phase of an auxiliary liquid which is also immiscible with water, whereby the agglomerates pass into this phase, and finally an aqueous phase - practically free of agglomerates - is discharged, and the agglomerates are separated of said stationary phase of auxiliary liquid by mechanical means in such a way that a quantity of liquid is dragged with the agglomerates The auxiliary fluid should be as small as possible, while any amount of possibly entrained auxiliary liquid is replaced, if necessary, by new addition in the separation stage.
