The features of the degradation process of petroleum hydrocarbons in the Kandalaksha Bay resulting from physical-chemical modeling

In this paper the results of studies of waters in the Kandalaksha Bay of the White Sea have been generalized; the chemical analysis and subsequent computer simulation using the software package for calculation of the equilibrium composition of multicomponent heterophase systems "Selector" have been conducted; an attempt to identify the most important factors determining the characteristics of the oil degradation process in the bay waters has been made.

Numerical modelling of dusting processes in ANOF-2 tailings impoundment

The paper considers issues related to study of multi-dispersed admixture transfer processes raised by wind current. Basing the 2D numerical CFD-model the influence of dusting surface height on the atmosphere surface layer downstream at dusting intensity variation has been evaluated. It has been shown that at dusting surface height growth the significant increase (from 50 % to 150 %) of contaminant concentrations in the atmosphere is predicted. The authors have come to the conclusion that full-scale 3D modelling study is required.
