Intensity of Neutralization of Dangerous Gases during Deposition with Small-Dispersion Water

Abstract:

The intensity of neutralization of dangerous gases (chlorine, sulfur dioxide, hydrogen cyanide, phosgene, hydrochloric acid, ammonia) is researching during deposition with small-dispersion water. For this purpose, a mathematical model of neutralization of a dangerous gas, which is lighter than air, with fine water was modified for use in neutralizing a dangerous gas, which is heavy relative to air. The model takes into account the main parameters of sorption (environmental conditions, physical and chemical properties of the dangerous gas, parameters of the liquid flow supplied for deposition), which minimizes the forecasting time and is critical in the elimination of an accident with a release of dangerous gases. It was found that when dangerous gases are deposited in a finely dispersed water stream, the determining parameter is the Henry's constant of the dangerous gas, rather than the intensity of the fine water stream. It is confirmed that for dangerous gases that are poorly soluble in water (have small values of Henry's constant), it is necessary to add additives to the water stream that increase the chemical activity of the solution.
