PROCESS FOR REMOVAL OF DISSOLVED OXYGEN FROM AN AGUEOUS MEDIUM USED IN STEAM GENERATION SYSTEM

摘要

Process for removing oxygen from an aqueous medium used in a steam generating system, the aqueous medium having hydrazine added thereto, wherein hydrazine-containing aqueous medium condensate formed in a condenser is exposed to ultraviolet light in the condenser hot-well, prior to being recycled to the steam generator. The exposure to ultraviolet light is for a period of time sufficient to effect removal of the dissolved oxygen by the hydrazine without the need to add chemical additives or catalysts to the system.
