The equations for calculating the diffusion limiting current, ilim, in steady-state voltammetry (known as the Peers equation in membrane science) and the transition time, τ, in chronopotentiometry (the Sand equation) are broadly used in electrode and membrane electrochemistry. The applicability of these equations is limited because they are deduced under the assumption of a constant diffusion coefficient...
The study is devoted to the integrated effect of acoustic treatment and addition of an inhibitor on viscosity-temperature properties and n-alkane composition in high-paraffin oil sludge. Ultrasonic treatment for 1minute and addition of the inhibitor at the concentration of 0.05% wt. decrease viscosity by 10 times and pour point by 8°С.
