ABSTRACT:
Water for use in steam generation systems, which is contained in a storage tank, is deoxygenated for use in the system by adding hydrogen to a stream of the water and intimately mixing the same, pressurizing the stream to a pressure of 60-150 psig, and contacting the pressurized stream with a catalyst bed of palladium or platinum dispersed on a solid carrier. The hydrogen reacts with the dissolved oxygen in the presence of the catalyst at ambient temperatures, to produce a deoxygenated stream of water containing less than 10 ppb of oxygen. The deoxygenated water can be returned to the storage tank or supplied directly to the steam generation system.
