Abstract

A nozzle for converting or separating a liquid/gaseous CO₂ into a dry ice includes a housing, a spherical chamber configured in the housing, and a first tangential inlet configured on the housing to tangentially inject the liquid CO₂ into the spherical chamber. The tangential injection creates a helical flow of the liquid CO₂ inside the spherical chamber causing flocculation at a desired pressure and temperature to ensure optimum phase transformation to create the dry ice. Further, a second tangential inlet is configured adjacent to the first tangential inlet to transfer a first secondary material into the spherical chamber to achieve highest possible degree of mixing, and resulting in the highest possible utilization of sub-cooling potential. Furthermore, one or more inlets are configured in the housing to receive a second secondary material to support expansion-based flocculation by thermally insulating the housing to achieve precooling of the spherical chamber.
