Oil is produced in the form of an oil emulsion due to the high depletion of deposits and significant water cut in wells. The formation of emulsions can lead to a number of complications in the operation of various field equipment, and sometimes even to emergency shutdowns or failures. Therefore, the study of the properties of demulsifiers and their effectiveness is an important task. The work investigates the surface-active properties of seven industrial demulsifiers produced in Russia, such as: interfacial and su...

This study is devoted to studying the properties of a new polymer sorbent based on polyvinyl alcohol and carboxymethylcellulose using infrared spectroscopy and thermogravimetric analysis. The influence of calcium chloride on the performance characteristics of the sorbent, such as oil capacity, floatation, moisture content and polymer degradation, is studied. The cross-linked matrix has improved properties: increasing the oil capacity and flotation time, retention of the structure when the sorbent is on the water s...
