ABSTRACT:
The entrainment of reaction medium in the vapor phase is decreased in a chlorine dioxide generator producing a gaseous mixture of chlorine dioxide, chlorine and steam from a boiling reaction medium and wherein generator liquor is recycled with make up chemicals by providing a tangential entry of recycled liquor to the generator in the vapor space above the liquid level in the generator and a helically-arranged baffle projecting inwardly from the generator wall at least in the height of the generator corresponding to the tangential entry opening into the vapor space. The baffle is arranged to be above the trajectory of the recycled liquor as it enters the generator. Decreased liquor entrainment enables the generator diameter to be decreased, with consequentially decreased capital costs.
