Solvay’s  MAX HT® sodalite scale inhibitor has allowed alumina refineries to operate free of sodalite scale in the heat exchangers of evaporation and digestion unit operations.


Used by refineries globally, MAX HT® enables all of our customers to enjoy increased heat transfer coefficients and evaporator steam economies that result in reduced energy consumption, caustic losses and maintenance costs (acid and labor).


MAX HT® 550 won the prestigious US EPA 2012 Presidential Green Chemistry Award as a result of the environmental benefits it provides to alumina refineries, such as lower CO2 emissions and fresh water consumption.
