Features of determining the mass of evaporation from solutions when calculating environmental damage to the environment
Abstract
The issues of environmental damage calculations are always relevant in the modern world for several reasons: increased attention to environmental protection from the world community; the development of legislation and international standards; the introduction of new technologies; public attention. The evaporation of pollutants into the environment is a serious problem, and the determination of the mass of evaporation makes it possible to assess environmental damage and develop measures to reduce it. The amount of damage caused by atmospheric air pollution is calculated based on the mass of the substance evaporated from the surface of such a spill. However, the evaporation model requires taking into account its multicomponent composition and changes in a number of parameters over time, but in practice the largest number of calculations are performed using methods where multicomponent solutions, in particular oil and petroleum products, are considered simplistically as quasi-one-component, and the calculations use averaged values of M and R. This paper presents comparative results of calculating the total mass of substances entering the atmospheric air during the bottling of an ideal solution, obtained from computer modeling with a given evaporation time step and calculations based on the obtained dependencies. It is shown that without the use of special programs, it is possible to determine the mass of evaporated substances, taking into account changes in the composition of the solution over time, as well as separately find the masses of each of the components of the solution entering the atmospheric air, which allows taking into account the corresponding atmospheric pollution and the time of complete evaporation of one of the components and the transition of the solution into a single-component liquid.
