Abstract. The pilot unit is developed for adaptation of the absorptive mathematical model in a scrubber of the Venturi on a finding of factors of phase equilibrium by algorithm working off in the absorptive processes of extraction SO2 on water. The technique of work by test tests of trapping CO2 for water which have shown adequate work of a scrubber of the Venturi in the cascade with a spray separator-cyclone separator is completed.

“…After a bromine explosion, the ozone concentration drops to a negligible level. As a consequence, the formation of BrO via Reaction (R5) drops to nearly zero, so that Br instead reacts with HO 2 or aldehydes to form HBr or with alkenes to form halogenated VOCs (e.g., Sander et al, 1997;Toyota et al, 2004;Keil and Shepson, 2006). In many models, including the present formulation, the reactions forming halogenated VOCs are simplified in a surrogate approach to form HBr instead.…”

On the contribution of chemical oscillations to ozone depletion events in the polar spring

Abstract. This paper presents a numerical study of the oscillations (or recurrences) of tropospheric ozone depletion events (ODEs) using the further-developed one-dimensional KInetic aNALysis of reaction mechanics with Transport (KINAL-T) chemistry transport model. Reactive bromine is the major contributor to the occurrence of ODEs. After the termination of an ODE, the reactive bromine in the air is deposited onto aerosols or on the snow surface, and the ozone may regenerate via NOx-catalyzed photochemistry or by turbulent transport from the free troposphere into the boundary layer. The replenished ozone then is available for the next cycle of autocatalytic bromine release (bromine explosion) leading to another ODE. The oscillation periods are found to be as short as 5 d for the purely chemically NOx-driven oscillation and 30 d for a diffusion-driven oscillation. An important requirement for oscillation of ODEs to occur is found to be a sufficiently strong inversion layer. In a parameter study, the dependence of the oscillation period on the nitrogen oxides' concentration, the inversion layer strength, the ambient temperature, the aerosol density, and the solar radiation is investigated. Parameters controlling the oscillation of ODEs are discussed.
