Many oil and gas fields are characterized by a high content of water, which complicates the extraction process. At the same time, the trend of increasing the volume of production contributes to a constant increase in the consumption of water resources. Due to the concentration of aggressive components of cooling water in heat exchange equipment and process pipelines, a number of interrelated problems arise during the continuous operation of the circulating water supply systems of petrochemical enterprises: deposition of salts, corrosion, and contamination by microorganisms. The high...

During processing, storage, and use, polymers are exposed to heat, light, oxygen, mechanical loads, and other effects. As a result, the properties of polymers change: mechanical strength and elasticity decrease, brittleness appears, color changes, the smooth surface becomes rough, etc. At present, the main raw materials for the production of antioxidants in the world are aromatic, low-molecular, and high-molecular amines and hydroxylamines, fatty acid amines, high-molecular alcohols, quinoline bases, imidazolines, thiourea derivatives, urotropine, phosphorus-containing compounds, as well as...
