WebJun 4, 2024 · Swenson Walker crystallizer is a continuous type crystallizer. This operation involves both heat and mass transfer. Crystallization is the formation of solid particles within a homogeneous phase. Its wide use has a two-fold basis; a crystal formed from an impure solution is itself pure. Swenson Walker Crystallizer Equipment; Types Of Crystallizers WebThe draft tube crystallizers (DT or DTB) ensure the ho- mogeneous mixture of the crystals with an internal axial pump. The energy supplied by the pump is much lower than that deployed by Forced Circulation, which signifi- cantly reduces attrition and breakage of the crystals, with a significant reduction in secondary nucleation.
