Investigation on processes for removal of chloramines from saturated sodium chloride brine solution

ERCO Worldwide, A division of Superior Plus LP, Saskatoon facility (“ERCO Worldwide-Saskatoon”) is a manufacturer of caustic soda, chlorine, hydrochloric acid and sodium chlorate. This facility has four fully developed underground brine wells. The brine solution as produced from the brine wells contains 26% sodium chloride in it. This saturated brine is purified and supplied to the electrolyzer system to produce caustic soda, chlorine, hydrochloric acid, and sodium chlorate. When brine containing chloramine is electrolyzed, it forms nitrogen trichloride (NCl3) along with chlorine.NCl3 is a contaminant in chlorine, and certain composition of this contaminant can possibly create hazardous conditions in the processing vessels. The project is to develop a suitable process to remove chloramines from brine. This project proposal focuses on the examination of various processes available to remove chloramine from brine, test them in bench scale and recommend a process, which is cost effective and is adaptable with the existing operation.
