Manufacturing of Corrosion Inhibitors and Flow Improvers from Recycling of Waste at Hail City, Saudi Arabia: Physicochemical and Electrochemical Studies on Steel in Petroleum Industries

“…Corrosion inhibitors are substances that are added in very small quantities for limiting the corrosion process by either inhibiting the anode or cathode reactions or both. − Corrosion inhibitors contain effective functional groups that enable them to be adsorbed on the metal surface such as hydroxyl and amine groups, as well as oxygen, nitrogen, sulfur, and heterocyclic materials. Organic and inorganic materials have been used as metal corrosion inhibitors in acidic, alkaline, and saline corrosive media and marine environments. − Environmental waste is recycled, and the results of recycling are used as metal corrosion inhibitors, whereas the waste of PET and PEAA plastics is recycled, and the recycled products are used as corrosion inhibitors for carbon steel used in the petroleum industry in acidic media and marine environments. − The surfactant materials prepared from plastic waste had an effective activity in adsorption on the surface of metals and protection of metals from corrosion, − as well as expired drugs were used as inhibitors. − Polymeric materials and heterocyclic compounds − were used to protect metals from corrosion. Corrosion of metals is a pervasive process related to the industry and to the daily use of metals in the environment.…”

Anticorrosion Agents for Carbon Steel in Acidic Environments: Synthesis and Quantum Chemical Analysis of New Schiff Base Compounds with Benzylidene

“…However, its inferior corrosion resistance necessitates a thorough investigation of corrosion processes in different environments. To counter this issue, various approaches, such as coatings, cathodic protection, and corrosion inhibitors, have been employed to prevent corrosion. , Understanding the corrosion mechanisms fully is crucial to effectively address specific corrosion problems with each protective technique. − Corrosion of carbon steel in acidic media is a persistent challenge faced by various industries, impacting the structural integrity and longevity of the equipment and infrastructure. As a result, the search for efficient anticorrosion inhibitors has been the subject of significant research. − …”

Synthesis, characterization, and evaluation of polymeric surfactants derived from PET plastic waste as green corrosion inhibitor of steel surfaces in marine environment for heavy industry

“…7,15 Adsorption of the surfactant on the metal surface can significantly alter the metal's ability to resist corrosion, 16,27–29 making research into the relationship between adsorption and corrosion inhibition critical. 31,33,40–43 PET was depolymerized using monoethanolamine and ethylene diamine in previous studies, 16–24 and the resulting nonionic surfactants were proven to be effective steel corrosion inhibitors in HCl. This article is part of a series aimed at reducing environmental pollution caused by the accumulation of plastic waste by recycling waste into modified products and evaluating the abilities of those modified products to prevent corrosion of metals and alloys in various aqueous conditions.…”

“…This article is part of a series aimed at reducing environmental pollution caused by the accumulation of plastic waste by recycling waste into modified products and evaluating the abilities of those modified products to prevent corrosion of metals and alloys in various aqueous conditions. 16–24 The present work is one from a series aimed at alleviating the environmental pollution caused by the accumulation of PET waste and evaluation of the products as corrosion inhibitors for metals and alloys in different corrosive environments. 1–18 The previously published papers focusing on the study of the corrosion in an acidic media such as HCl, H 2 SO 4 , and HNO 3 , all contain H + ions (investigate the effects of H + presence), with the conclusion of different inhibition efficiencies.…”
