CARBON-DIOXIDE CORROSION INHIBITOR FOR LOW AND MEDIUM PRESSURE STEAM GENERATING PLANTS Russian patent published in 2022 - IPC C23F11/14

Abstract RU 2764251 C2

FIELD: power engineering.

SUBSTANCE: invention relates to inhibitors of carbon steel corrosion; it can be used in the organization of a water-chemical mode of a steam-water path of a power unit with reel boilers, recovery boilers of low and medium pressure. The inhibitor includes components at the following ratio, wt. %: monoethanolamine (MEA) 16-18, dimethylethanolamine (DMEA) 15-17, cyclohexylamine (CHA) 2-4, and water is the rest.

EFFECT: reduction in the speed of equipment corrosion due to carbonic acid neutralization, and increase in pH value of steam and condensate, as well as maintenance of normalized values of pH of boiler water.
