Testing of magnesium complexates of nitrilotrimethylene phosphonic acid to prevent metal corrosion and salt deposits

Abstract

The work is devoted to testing magnesium complexonate nitrilotrimethylenophosphonic (NTP) acid as a reagent that reduces the corrosion rate and the amount of mineral deposits formed. The corrosion rate was controlled by measuring the polarization resistance of water using the Expert-004 device. In the course of the work done, a high efficiency of inhibition of scale deposits and corrosion was established in the boiler house of the city of Polevsky, operating on the water of the city pond. A complex scale and corrosion inhibitor Mg-NTF was proposed and tested under production conditions in the technological systems of URAL-Sakhar 1 LLC, which made it possible to significantly reduce operating and capital costs.
