In boiler systems, water quality directly impacts operational efficiency and service life. Dissolved oxygen in water is one of the primary culprits causing metal corrosion. Therefore, effectively removing dissolved oxygen from water is crucial for protecting internal metal components and extending boiler longevity.
01 The Function and Importance of Acetone Oxime
Function of Acetone Oxime
High-Efficiency Deaeration: Acetone oxime reacts chemically with dissolved oxygen in water to form acetone oxime oxide, thereby effectively removing dissolved oxygen. The chemical equation for this reaction is: 2C₃H₇NO + O₂ → 2C₃H₆NOO. Following the reaction, the acetone oxime oxide precipitates in the water, achieving the deaeration objective.
Reduction of Corrosive Substances: Beyond direct oxygen removal, acetone oxime diminishes other corrosive elements in boiler water, such as carbon dioxide, thereby enhancing protection against corrosion within the boiler system.
Environmentally friendly: Compared to traditional deoxidants, acetone oxime is relatively safe and does not cause environmental pollution or harm.
The Importance of Acetone Oxime
Protecting boiler equipment: Dissolved oxygen is one of the primary culprits causing metal corrosion within boiler systems. By removing dissolved oxygen, acetone oxime effectively safeguards internal metal components from corrosion, thereby extending the boiler’s service life.
Enhancing Boiler Operational Efficiency: Corrosion degrades boiler equipment performance and may cause failures. Acetone oxime reduces equipment failures caused by corrosion, thereby improving boiler operational efficiency.
Reducing Operational Costs: By effectively removing dissolved oxygen, acetone oxime diminishes maintenance and replacement costs associated with corrosion. Concurrently, acetone oxime diminishes other corrosive substances within the boiler system, further lowering operational expenses.
Environmental compliance: With heightened environmental awareness, emission standards for boiler systems grow increasingly stringent. As a low-toxicity, eco-friendly deoxidiser, acetone oxime better aligns with contemporary environmental requirements.
02 Instrumentation Analysis
Applicable to thermal power generation, chemical fertilisers, metallurgy, environmental protection, pharmaceuticals, biochemistry, food processing, and municipal water supply industries. Suitable for analysing acetone oxime concentrations in boiler feedwater, condensate, steam water, internal generator cooling water, furnace water, and natural water sources.
Operating Principle
Acetone oxime is first hydrolysed by heating in dilute acid to produce hydroxylamine, which reduces ferric iron to the corresponding ferrous iron (II). The ferrous iron (II)-phenanthroline complex remains stable at pH 2.5–9, with colour intensity directly proportional to the quantity of ferrous iron present. The instrument employs photometric principles for measurement. According to the Lambert-Beer law: when a beam of monochromatic parallel light passes through a coloured solution, a portion of the light energy is absorbed. If the liquid layer thickness remains constant, the degree of light energy absorption (absorbance A) is directly proportional to the concentration of coloured substances in the solution.
