“…The strength of inhibitor is reduced significantly in the presence of crude M irrespective of whether distilled water or brine solution was used. Some researchers have proposed that changes in interfacial tension between liquid hydrocarbon and aqueous phases due to the presence of inhibitor may be the reason for this unexpected behavior [38,39]. These surface active inhibitors decrease the surface tension and consequently improve the contact between the liquid phases, which allows increased gas diffusion with a lower barrier to mass transfer [40].…”

“…According to the literature [35][36][37], the exchange of macromolecules between the surface layer and the bulk phase can be neglected, but the exchange of monomers between different regions of the surface layer has to be taken into account. There are two main parts of the surface film: one is the proximal region (a relatively narrow concentrated region contiguous to the gas phase), the other is the distal region (a region of tails and loops protruding into the bulk where the concentration of monomers is lower) [35].…”

“…The first of these methods is the drop profile analysis tensiometer, which is used to measure surface tension by analyzing the shape of a droplet (bubble) [70][71][72], which can be operated in the low-frequency range from 10 -3 to 0.2 Hz. The second device is the capillary pressure tensiometer, which is used to directly measure capillary pressure [73] at higher frequencies of 0.1-100 Hz (in some cases, up to 500 Hz).…”

“…Therefore, the discussed method of an oscillating barrier is used at oscillation frequencies not higher than 0.2 Hz [118,122]. The method was applied in [123][124][125][126][127] and discussed in detail in a recent review [128].…”
