摘要: Carbonation of ammoniacal sodium chloride brine in the ammonia soda process wherein a phenol-free or phenol deficient ammonia is used as make-up ammonia, the improvement being that one or more phenolic compounds are added to the process in an amount sufficient to reduce the carbon dioxide content of waste gas leaving the carbonation stage to less than 12 percent carbon dioxide.
