PROCESS FOR THE REMOVAL OF ELEMENTAL OXYGEN BY MEANS OF A REDUCING AGENT IN A COOLANT CIRCULATING IN ONE OR MORE CLOSED CIRCULATIONS,AND APPARATUS FOR THE REMOVAL OF ELEMENTAL OXYGEN

摘要

The removal of elemental oxygen with the aid of a reducing agent from a liquid coolant which circulates in one or more circulations and from which salts are to be removed simultaneously in an ion exchanger mixed-bed filter (5) can be effected without substantial additional expense in terms of apparatus by at least partially loading the anion or cation exchanger resin present in the mixed bed filter (5) with the said reducing agent. The reducing agent is added via a metering means (6) upstream of the mixed-bed filter (5) in the secondary circulation (2).
