Abstract

For the non-clogging, fractional desublimation of vapor-phase solids contained in a gas-vapor mixture, the gas-vapor mixture, exiting at high velocity from a nozzle, is mixed with a cooling gas, likewise exiting at high velocity from another nozzle. The gas-vapor mixture and the cooling gas flow toward each other, the axes of the two gaseous streams being a straight line. Fractional desublimation of the solids is attained by adjustment of flows leading to the regulation of the temperature and residence time of the cooled gas-vapor mixture. This desublimation system is capable of degrees of efficiency and solids purities higher than 99%.
