Successful defense of a doctoral dissertation on a relevant topic corresponding to SDG 9, SDG 12, SDG 14

Bold Amangul successfully defended her doctoral dissertation for the degree of Doctor of Philosophy (PhD) on the topic: "Development of anti-corrosion coatings for oil field equipment" under EP 8D07101- "Petrochemistry"at the Kazakh National Research Technical University named after K.I. Satpayev. The work was carried out at the Department of Physical Chemistry, Catalysis and Petrochemistry of the Faculty of Chemistry and Chemical Technology of Al-Farabi Kazakh National University and in the Laboratory of Electrochemistry and Nanotechnological Processes of JSC "Institute of Fuel, Catalysis and Electrochemistry named after D.V. Sokolsky". The dissertation was presented in Kazakh. The dissertation was completed under the supervision of domestic scientific consultant Larissa Ravil’evna Sassykova, professor of the Department of Physical Chemistry, Catalysis and Petrochemistry of Al-Farabi Kazakh National University, and foreign scientific consultant - Vahramyan Tigran Ashotovich, professor, head of the department of innovative materials and corrosion protection of the Mendeleyev University of Chemical Technology of Russia, Moscow, Russia. The dissertation work is of an applied nature and is devoted to a pressing problem of the oil and gas industry and petrochemical production - the development of anti-corrosion coatings on metal surfaces in order to protect equipment at oil refineries. A composition of a phosphating solution based on Majef salt and hydroxylamine has been developed for obtaining phosphate coatings on iron samples, which allows eliminating the use of heavy metal salts (copper, nickel, zinc, chromium), which have a negative impact on the environment. Phosphating solutions have been developed based on rust converters using organic nitro compounds as accelerators, which allow obtaining low-temperature coatings with high corrosion resistance. Optimum conditions for applying zirconium oxide coatings used as adsorption layers under paint and varnish coatings have been determined. The obtained phosphate coatings from solutions of rust converters were tested in industrial water of the Pavlodar Petrochemical Plant (PPP). The topic of the dissertation corresponds to the objectives of the UN SDGs: SDG 9. Build resilient infrastructure, promote inclusive and sustainable industrialization and implement innovation. SDG 12. Ensure sustainable consumption and production patterns. SDG 14. Conserve and rationally use the oceans, seas and marine resources for sustainable development. Obviously, experimental tests on the creation of nanoscale ceramic coatings developed in the dissertation can replace energy-intensive and environmentally hazardous processes of chromating and phosphating, widely used in oil refineries.
