Abstract
The entrainment of reaction medium in the vapor phase and the entrainment of gaseous phase in liquid phase are decreased in a chlorine dioxide generator (12) producing a gaseous mixture of chlorine dioxide, chlorine and steam from a boiling reaction medium (14) and wherein generator liquor is recycled with make up chemicals. These results are achieved by generator modifications, which include tangential entry (30) of recycled liquor to the generator (12) in the vapor space (16) above the liquid level in the generator (12), and the provision of a baffle (34, 50) projecting inwardly from the generator wall in the vapor space (16) and arranged to be above the trajectory of the recycled liquor as it enters the generator (12). These modifications enable the generator volume to be decreased substantially, with consequentially decreased capital costs.
