AI Technical Summary
Existing modified polyether demulsifiers have weak resistance to ion interference, low oil droplet coalescence efficiency, and poor compatibility with auxiliary functional components when treating complex industrial quench water systems, resulting in low demulsification efficiency and easy secondary emulsification.
The technology employs a combination of oleo-esterified modified polyether and multifunctional synergistic additives. Through an integrated crosslinking-chelation-synergistic design, it combines phosphonamide groups to chelate metal ions, a mild crosslinking network to promote oil droplet aggregation, and intermolecular multi-force synergistic demulsification. Combined with directional esterification and azeotropic dehydration processes, it enhances interfacial activity and demulsification efficiency.
Under hard water conditions, the demulsification efficiency is increased by 30%-50%, the residual oil content in the effluent is reduced to below 10mg/L, the ability to chelate metal ions is strong, the dosage of demulsifier is reduced by 20%-30%, and the environmental friendliness is improved by 30%.
