About the Results of Calculation of Adsorption for Liquid-Crystalline Nanodemulsifiers on the Basis of the Oxialkylene Block Copolymers

Nanodemulsifiers with the properties of crystalline liquids, intramolecular interblock activity and eternal intramolecular nanomotors

“…The APS is also determined based on individual points of scientific novelty of the proposed discovery which are closely linked to the name of the discovery itself: "The phenomenon of simultaneous destruction of oil-water and oil-water emulsions". The practical significance of the discovery is confirmed by the results of pilot testing and the introduction of polynanostructured nanodemulsifiers of the "IKHLAS" brand in rather complex fields of the Republic of Kazakhstan [14][15][16][17][18]25,26,29,34,35] . The annual actual economic efficiency from the implementation of this discovery stands at approximately $10,846,000 and in the period 2021-2023 $32,538,000 (there is an official certificate of economic efficiency from the implementation of the authors' scientific discoveries in the oil fields of the Republic of Kazakhstan).…”

“…Demulsifiers with the visual aggregate state of a crystalline liquid are demonstrated in Figure 1: (a) (b) (c) Figure 1. Some samples of nano-demulsifiers "IKHLAS" with visual aggregate states of crystalline liquids (for the first time) in glass bottles in vertical and horizontal positions: (a): "IKHLAS"-6003-20; (b): "IKHLAS"-5003-15; (c): "IKHLAS"-4003-10 [29] .…”

“…When dosing a demulsifier into crude oil, a redistribution of oligomer homologues occurs in oil-water and oil-water emulsions. Monoesters with relatively low n values, i.e., the most hydrophobic components are distributed in water-oil emulsions, and components with relatively high n values, i.e., relatively hydrophilic components pass into the oil-water emulsion [35] . Due to a similar redistribution of oligomer homologues in crude oil, the phenomenon of simultaneous destruction of water-oil and oil-water emulsions occurs and as a result, commercial oil is obtained with a water content of no more than 0.5%, as well as produced water (formation water) with an oil content of no more than 50 mg/dm 3 , which comply with current standards [20,21] .…”

“…For perpetual nanomotors such as block copolymers of ethylene (-CH2CH2O-) and propylene (-СН2-СН2-CH2О-) oxides based on glycerine; the cross section (S) of the molecules is S = 78 × 10 −20 m 2 [29] . It is known that the cross section (S) of the oxyethylene chain is 23 × 10 −20 m 2 [30] .…”
