Regeneration of Used Fire-Resistant Triaryl Phosphate Oils

  • INNOVATIVE TECHNOLOGIES OF OIL AND GAS
  • Published:
Chemistry and Technology of Fuels and Oils Aims and scope

A method is proposed for the regeneration of fire-resistant triaryl phosphate oils by heat treatment with anhydrous neutralizing agents with subsequent distillation of the reaction mixture. This treatment leads to the elimination of aging products in used triaryl phosphate oils such as acids, phenols, condensation products, wear metals, introduced sludge, and water. This method gives high yields of the regenerated oils meeting the standard requirements of fire-resistant triaryl phosphate oils for reuse.
