Title:
REMOVAL OF BROMINE IN CHLORINE
Document Type and Number:
Japanese Patent JPS5992903
Kind Code:
A
Abstract:
PURPOSE: To remove bromine from chlorine containing less than specific amount of bromine, industrially and economically, by washing the chlorine with water free from bromine.
CONSTITUTION: Bromine is removed from chlorine containing ≤2,500ppm of bromine, by washing the chlorine with ≥1pt.wt., preferably 3W150pts.wt., based on 1pt.wt. of the chlorine, of water essentially free from bromine. The washing is preferably carried out by the counter-current contacting method using a packed column, however, any methods capable of essentially washing chlorine can be used for the purpose. Since the process can be combined with an electrolytic plant, it is industrially advantageous.
