Sodium Sulfate

Na₂SO₄ Production Plants

Highlights

Production of high purity Na₂SO₄ from brine:

  • Na₂SO₄ ≥ 99.5 %
  • H₂O ≤ 0.5 %
  • Close granulometry
  • Minimal fines

Feedstocks

Na2SO4 brine feed – all concentrations


Process Characteristics

  1. Utilization of glauber salt route to minimize energy consumption
  2. Direct conversion of glauber salt to anhydrous in melter
  3. Crystal size can be selected over a wide range
  4. Close crystal size with minimum fines
  5. Low product moisture content of product from fluid bed dryer

Plant Characteristics

  • Wide range of feed compositions
  • MVR or multiple effect depending on utility costs
  • Cooling water requirement minimised by utilization of brine for condensation
  • High plant availability
