Study on Corrosion Scale Inhibitor for Blast Furnace Gas TRT System

Abstract:

Cyclohexylamine, morphine, ethanolamine, propiolic alcohol, seventeen alkenyl amide ethyl imidazoline, water depolymerization malaya acid anhydride, etc were chosen as the raw material of corrosion scale inhibitor in view of corrosion scaling reason and characteristic of blast furnace top gas pressure recovery turbine unit. The optimized formula of corrosion inhibitor have been obtained through orthogonal experiment. Corrosion and scale inhibitor performance were evaluated respectively by static weight-loss method, dynamic weight-loss method and calcium carbonate deposition. The results show that when these components are reasonable distributed, the corrosion effect is satisfied. When water depolymerization malaya acid anhydride is combined with the corrosion inhibitor, the corrosion and scale inhibition efficiency of composite inhibitor are more than 90%. Simulation blast furnace gas is adopted in dynamic simulation experiment, the corrosion inhibition efficiency is over 92%.
