Electrical tomography (ET) techniques are used for determining material distributions within the detection volume of the sensor, and they are based on measuring the material-dependent responses of electrical excitation signals. The state of the art i

Pigging of a multiphase (i.e. liquid/gas) pipeline can result in a large "pigged" liquid slug when a normal (i.e. non-by-pass) pig is used. This requires a large separator or slugcatcher, or otherwise accepting production deferment during pigging. Th

Equilibrium surface tension isotherms of sodium dodecylbenzene sulfonate (DDBS) are obtained at various fixed concentrations of NaCl. The contents of unsulfonated dodecylbenzene (DDB) in the used surfactant sample is determined by processing the surf

The main target of this study is to develop a theoretical method for determining small contents of dodecanol in samples of sodium dodecyl sulfate (SDS) by a detailed analysis of surface-tension isotherms. As a tool for our analysis, we employ the van

By NMR and static and dynamic light scattering we investigated how the micelle size, shape, and aggregation number vary during the solubilization of triolein in mixed aqueous solutions of the nonionic surfactant C12En (n = 5 or 6) and the nonionic tr

A theoretical model of oil solubilization in micellar surfactant solutions is developed. We consider oils that are practically insoluble in pure water, like triolein and other triglycerides. The nonionic micelles, which are capable to solubilize such

We investigated the kinetics of solubilization of triglycerides (triolein and soybean oil) by observing the diminishing of individual oil drops (radius ≤ 50 μm) in a micellar surfactant solution. We used two solubilization cells. Cell no. 1 is a c

In the preceding paper of this series we studied the effect of several oils of different chemical structure on the foaming properties of sodium dodecylbenzenesulfonate solutions. A straightforward correlation was found between the foam stability and

Foam tests and model experiments with sodium dodecylbenzenesulfonate solutions are performed to clarify how the foam stability and the foaminess are affected by several oils of different chemical structure. The foam tests show that 2-butyloctanol (2B

Instability driven by diffusion flux across an asymmetric liquid film is theoretically investigated. To specify the system, we consider an oil−water-air film; the transported species are oil molecules. The latter are dissolved (solubilized) at the
