摘要
Intimate contacting of plural, physically disparate phases is achieved by establishing a current of axially extending, axially symmetrical helical flow of a first phase; separately establishing a current of coaxially extending, rectilinear flow of a physically disparate second phase, the currents of said first and said second phases being maintained physically separated from each other; circulating and directing said currents which comprise the plural phases to a zone of restricted flow passage with respect to said helical flow, whereby said plural currents converge and are intimately, homogeneously admixed and whereas such zone of convergence the momentum of the first phase helical flow is at least 100 times greater than the momentum of the second phase, coaxial rectilinear flow; and thence abruptly changing the velocity field of at least one of said plural phases, while at the same time maintaining the general direction of flow of said admixed plural phases, and whereby phase separation of the product of admixture results enabling easy recovery thereof. Such intimate contacting is especially desirable for concentrating dilute solutions of phosphoric acid with hot air.
