Формирование дополнительного показателя для оценки вязкости деградированной нефти при разливе на морской поверхности

Abstract

The relevance and the possibility of introducing an additional information attribute in the study of the viscosity of degraded oil are considered. The method for the formation of this attribute is presented – logarithmic index of relative viscosity (γ). Taking into account the known interrelationships of individual processes occurring with oil in the aquatic environment, it is shown that with a certain dynamics of mutual changes in fractional portions Fem and Fev the introduced indicator reaches its minimum. An example of using the proposed indicator in assessing the level of pollution of the surface layer of the atmosphere with vapor of light fractions during oil spill is given. Thus, the minimum γ indicates the joint occurrence of evaporation and emulsification processes, in the absence of a minimum γ only the evaporation process takes place. At minimum γ based on the results of previous studies, a qualitative conclusion can be drawn about the high degree of pollution of the near-surface layer of the atmosphere. To quantify such pollution, you can use the data obtained previously during similar studies for a particular type of oil.
