A problem often associated with the manufacture of hydrochloric acid by combustion processes is that the hydrochloric acid is contaminated by dissolved chlorine. Conventional practice is to remove the free chlorine from the hydrochloric acid by adding reducing agents. As an alternative, an electrochemical chlorine reduction process has been developed and investigated both on a laboratory and pilot‐plant scale. The advantages of this method are that it obviates the need to add chemicals and effectively prevents chlorine corrosion.
