Water entropy-driven electrochemical relaxation of dissolved oxygen in aerated refinery wastewater

Abstract

The results obtained in this paper show dissolved oxygen monolayer chemisorptions in gas bubbles in aerated and saturated refinery wastewater is water entropy-driven relaxation processes. Dissolved oxygen and hydrogen electrons affinity keep constant liquid water molecules entropy. In the time period of water molecules crystallization on water input, or volatilization on air output on active adsorption or condensation nucleuses depending on aeration regimes, oxygen adsorption heat keeping constant liquid water entropy enabling coupling with positive or negative hydrated hydrides entropy change. The relationship between oxygen monolayer adsorption heat to Langmuir adsorption isotherm and oxygen diffusion transfer energy after saturation time are found on the basis of previously obtained experimentally data (temperatures and stationary oxygen concentrations). In this paper, the energy efficiency depending on oxygen entropy level and oxygen total energy level between drift and saturation time period is also examined. © 2013 Balaban Desalination Publications.
