PARAMETERS OF THE ACTUAL AREA OF CONTAMINATION UNDER THE CONDITIONS OF THE RELEASE (SPILL) OF HYDROGEN CHLORIDE
The article is devoted to the problem of calculating the actual zone of contamination in the event of a release of hazardous chemicals using an interpolation estimate based on the results of practical studies carried out in relation to ammonia and chlorine. The prospects for the application of a semi-empirical model for calculating the parameters of the actual zone of contamination, which is formed during the release (strait) of hydrogen chloride, are considered. A method is proposed for calculating the curtain efficiency coefficient in relation to an inert impurity and an impurity capable of absorption interaction with water. Using an interpolation estimate based on vapor density and water solubility, the depth of the actual zone of contamination, the absorption capacity and transmission coefficient of the water curtain in relation to hydrogen chloride were determined. On the basis of the data obtained, the depth of the actual infection zone was calculated under the conditions of setting up water curtains during rescue operations. An estimate of the change in the depth of the actual zone of infection as a result of a change in pressure in the bag sprayer is given.
