The paper studies the physicochemical properties of import-substituted and export-oriented nitrogen, amine and phosphorus new composite inhibitors for corrosion protection of steels as well as scaling obtained from local raw materials and industrial wastes. Inhibiting properties of corrosion and mineral salt deposit accumulation in acid and hydrogen sulfide environments have been determined. It was found that the efficiency of the inhibition process with the use of composite inhibitors in acidic and hydrogen sulfide environments obeys the Langmuir law. The values of activation energy of the adsorption process in these media and thermodynamic values (∆H, ∆S, ∆G).
Currently, the Republic of Uzbekistan deservedly pays attention to the introduction of inhibitors to protect equipment from corrosion and scaling in production. The use of inhibitors allows several times to increase the service life of expensive equipment. In this regard, the most effective inhibitors of neutral and slightly alkaline media are nitrogen, amine and oxygen-containing organic compounds [1-3] as well as zinc organophosphonic acids, which effectively prevent corrosion and deposits of mineral salts on the surface of equipment.
In the objectives of the Development Strategy of new Uzbekistan for 2022-2026, it is noted that the volume of construction and chemical materials production should be doubled, the raw material base should be expanded by involving non-traditional non-metallic raw materials and secondary resources, non-waste technology within the "green economy" should be developed and introduced. Proceeding from the task set in the work methods of regeneration of composite sorption materials (CSM) after use in wastewater treatment, synthesized based on rotor slag of Djizakh battery plant are investigated. The recovery of CWM by thermal regeneration, which is the treatment of the sorbent by steam or gas at 110°-400℃, is shown. High temperature thermal regeneration is considered to be the most intensive method of sorbate desorption.
