Why Foam Control Matters

During wet-process phosphoric acid production, phosphate rock reacts with sulfuric acid to produce phosphoric acid and calcium sulfate (gypsum). Carbon dioxide (CO₂) released from the phosphate rock, along with other gas-generating side reactions, creates excessive foam within the reactor.

This foam reduces operational efficiency by:

  • Limiting available reactor capacity
  • Reducing pumping efficiency
  • Increasing fugitive emissions
  • Causing product losses to scrubber systems
  • Reducing reactor circulation
  • Accelerating scale formation
  • Increasing filter plugging
  • Reducing phosphoric acid filtration rates
  • Increasing plant downtime

Without effective foam control, these issues reduce production capacity and increase operating costs.

Why Arkema's Defoamer Technologies?

Mechanical gas removal systems can help reduce foam but often require significant capital investment while providing only partial control.

Arkema's advanced defoamer technologies provide a more efficient and economical solution by reducing the surface tension surrounding gas bubbles, allowing entrained gases to escape quickly while improving reactor performance and process stability.

With decades of experience serving phosphate producers worldwide, Arkema develops customized defoamer formulations tailored to each customer's raw materials, operating conditions, and production objectives.
