Product Usage of Acetone Oxime (DMKO)
Acetone oxime is primarily used as a chemical oxygen scavenger in industrial boiler feedwater systems. Compared with conventional boiler deoxygenation agents, it offers advantages such as low dosage, high deoxygenation efficiency, non-toxicity, and no environmental pollution.
It is an ideal chemical for shutdown protection and passivation treatment of subcritical boilers, and also serves as a preferred alternative to traditional deoxygenators such as hydrazine in medium- and high-pressure boiler feedwater systems.
