Abstract
Abstract A mixing method. A crude mixture of a gaseous and a liquid phase is contained in an elongated tubular inner space and in an annular outer space surrounding and communicating with the inner space. Jets of the mixture are forced from the inner into the outer space at longitudinally spaced locations of the inner space, and their intrusion into and dispersion in the mixture in the outer space effects more intimate admixture of the phases.
