Process for treating substances in different phases, such as the treatment of substances in liquid, semi-liquid or paste form, by another notably gaseous phase

摘要

Apparatus and process for treatment of materials in different phases, one of which is in a fluid phase and another of which is in a gaseous phase, wherein the material in fluid phase is introduced as a stream within the axis of the gaseous phase in helicoidal flow for subsequent passage through a confined zone whereat a substance to be treated is introduced at the level of the smallest section of the confined zone.
