The Destruction Process

RRA destroys harmful refrigerants using advanced argon plasma-arc furnace Montreal Protocol approved destruction technology.

This process, known as pyrolysis, differs from traditional incineration, providing a more controlled and environmentally responsible approach.

Fluorocarbon refrigerants, typically made up of hydrogen, fluorine, chlorine, and carbon, are injected into a specialised chamber where argon plasma is maintained at an extreme temperature of approximately 10,000°C. The intense heat breaks the molecular bonds, forming hydrogen fluoride (HF) and hydrogen chloride (HCl).

These hot acid gases are neutralised using a water and sodium hydroxide (NaOH) solution called caustic soda. The process results in by-products, including sodium chloride (NaCl) salt, sodium fluoride (NaF) salt, water, and a minimal amount of carbon dioxide (CO2). The salt solution produced is safely processed through the sewer system.

The Plascon site operates under strict Victorian EPA and Melbourne Water approval limits and Federal government requirements to reach a minimum destruction rate efficiency of 99.9999%.

This innovative destruction method ensures safe and effective disposal, minimising environmental impact and supporting sustainable practices.
