CA 2625719

It is intended to provide a method of producing a chlorine gas having a small bromine content, an aqueous sodium hypochlorite solution having a small bromic acid content, and liquid chlorine having a small bromine content. More specifically speaking, a chlorine gas is produced by a production method comprising: (A) the step of, in a gas washing unit comprising a column tower or a plate tower, washing a chlorine gas containing bromine, which is supplied from the lower part of the gas washing unit, by the counterflow gas/liquid contact with liquid chlorine which is supplied from the upper part of the gas washing unit; and (B) the step of taking out the thus washed and purified chlorine gas from the upper part of the gas washing unit, wherein the weight ratio of the chlorine gas to the liquid chlorine which are supplied in the step (A) is form 1/1.0 to 1/0.3.

L~invention concerne un procédé de fabrication de chlore gazeux présentant une faible teneur en brome, d~une solution aqueuse d~hypochlorure de sodium présentant une faible teneur en acide bromique, et de chlore liquide présentant une faible teneur en brome. Du chlore gazeux est plus précisément obtenu par un procédé de fabrication comprenant : (A) une étape de lavage de chlore gazeux contenant du brome dans une unité de lavage de gaz comprenant une colonne ou une colonne à plateaux, le gaz étant introduit par la partie inférieure de l~unité de lavage de gaz, le lavage ayant lieu par contact gaz/liquide à contre-courant avec du chlore liquide introduit par la partie supérieure de l~unité de lavage de gaz ; et (B) une étape de retrait du chlore gazeux ainsi lavé et purifié par la partie supérieure de l~unité de lavage de gaz, le rapport massique entre le chlore gazeux et le chlore liquide introduits à l~étape (A) étant compris entre 1/1,0 et 1/0,3.
