Thermodynamic diagnostic of electrons densities in gas bubbles in aerated saturated refinery wastewater

Abstract

Electro-chemical potentials of adsorbed hydrogen on active centers could help energy efficiency of oxygen transport in the aerated saturated refinery wastewater to be optimized. In stationary regime, by using of the same membrane diffuser, the true understanding of the spontaneous fastest parallel exchange of electrons by Boltzmann collisions and slowest oxygen mass diffusion transport by adsorption can be attained. This paper presents diagnostic of electrons density in the gas bubbles in aerated saturated refinery wastewater, according to the criteria of partial local thermodynamic equilibrium (PLTE). By the different stationary air flows, different water tank height and different motor oil content it was obtained that water entropy driven electrons density transport through the monolayer of the adsorbed air bubble controls energy efficiency of oxygen transport. © 2012 Desalination Publications.
