Inhibition of the coil-helix transition of gelatin and retardation of the gelation process of the system as a whole is an important scientific problem. The solution to this problem will make it possible to maintain the properties of gelatin solutions for a long time without changing their rheological characteristics. In this work, by the method of dynamic mechanical analysis, the dependences of the time profile of gelatin solutions depending on the concentration of 10, 13 and 16 wt.%, as well as the different diss...

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...
