ABSTRACT:
It has been discovered that ammonia and amines are useful to increase the pH and corrosion resistance of high density brines, such as zinc bromide brines, without significantly reducing their densities. The ammonia or amine additive is preferably incorporated by contacting the brine with the additive which is in the vapor phase. Optionally, a substituted carboxylic acid, such as hydroxy carboxylic acid, may be used to increase the amount of ammonia or amine that can be included in the high density brine without precipitation of salts.
