Main applications:
- in oil production industry to prevent or to limit deposits of difficultly soluble compounds (mainly carbonates) in the process of oil production, preparation and transportation;
- for prevention or limitation of deposits of difficultly soluble compounds (mainly carbonates) in heat exchangers, in systems of hot water supply of open and closed type at temperature up to 130 °C;
- in pulp-and-paper industry as a stabilizer of hydrogen peroxide properties while cellulose bleaching instead of sodium silicate;
- in the process of highly mineralized water utilization.
