MAX HT® - A scale control technology used in the alumina process.

MAX HT® prevents the formation of impurities and contaminants in heaters resulting in optimized energy consumption and reduced emission.

MAX HT® is a scale inhibitor that eliminates sodalite scale from heat exchangers and contributes to the sustainability of the alumina industry. It reduces both energy and fresh water consumption, in addition to solving a legacy production challenge within the alumina industry. MAX HT® Technology prevents the formation of solid particles, it results in higher heat transfer rates reducing the need for energy to maintain high temperatures and enabling the generation of fresh condensate which is recycled in process, decreasing the injection of fresh water by 20%.

Key features

  • An estimated reduction of 0.54-3.9 billion kg of CO2 emissions, and 38-116 million kg of acid waste reduction when applied to the total alumina production from 20 plants
  • Billions of gallons of fresh water is saved annually

Profitability

  • The average net savings ranges from $2-6 per ton of Alumina
  • Reduction in the cost of energy consumption and an overall increase in the productivity of the production process
