Compositions for the treatment of water-steam boilers especially medium and high pressure systems.

摘要

Treatment compositions WATER-VAPOR SYSTEMS, ESPECIALLY IN BOILER MEDIUM AND HIGH PRESSURE. They include: deoxygenating agent and passively METAL SURFACES AS hydroxylamines; Alkalizing agents alkanolamines AS TO PHASE FOR LIQUID AND VAPOR cyclic amines. SOLUTIONS CONDITIONERS further comprise dispersant-SLUDGE FOR USE ON MEDIUM AND HIGH PRESSURE. CATALYST COMPRISING INCREASING OXYGEN uptake rate. Advantageously comprise: diethylhydroxylamine AS deoxygenating agent in concentrations from 5 to 26 per cent; Triethanolamine as alkanolamines AND / OR AS cyclohexylamine and morpholine cyclic amines in concentrations 7 TO 40 PERCENT; Copolymers of acrylic acid / acrylamide and its derivatives as CONDITIONERS-DISPERSING SOLUTIONS sludge present in concentrations of up to 10 percent; Hydroquinone as a catalyst in concentrations of 0.1 to 0.5 percent. SYSTEMS USED IN STEAM-WATER, PREFERABLY boiler systems at medium and high pressure.
