Universalism of Hydrogen Sulfide and Carbon Dioxide Corrosion Inhibitors in Conditions of Oil Production and Processing

Approximate analytical overall isotherms: lateral interactions of adsorbate species and patchwise topology

“…The adsorption functions represent dependencies of coverage on pressure for the former and on ionic activity or concentration (for solutions with constant ionic power) for the latter. The last case seems promising, in particular, for modeling of the corrosive environment where there exists a competition between aggressive surface-active ions (as, e.g., Cl-ions whose adsorption is sure to be considered involving lateral interactions) and inhibitor's molecules for the surface's active centres at which intermediate adsorption complexes are being formed [ 16 , 17 , 18 ].…”

“…We can numerically calculate now x i ¼ x i ðy FG ¼ y i Þ for all i ¼ 0; I due to Eq. (18). For these x i we calculate then y i ¼ y i ðx i Þ due to Eq.…”
