Expertises ([TEXT NOT REPRODUCIBLE IN ASCII] 1998) had demonstrated, that as a result of pressure bump of warm damp air in area of cooling towers and the determined removal from them the special microclimate alee is created.
The problem consists that near to a zone of a layout of group of cooling towers at a territory jfchemical (or oil refining) enterprises there are the potential sources of pressure bump in an atmosphere of those or diverse harmful matters, some of which are introduced in Table 5.
Vedeneyev ([MATHEMATICAL EXPRESSION NOT REPRODUCIBLE IN ASCII] 1977) had demonstrated, in particular, that calorific pressure bump of cooling towers at small speeds of a wind can render essential influencing on intensity of eddy diffusion that causes appreciable magnification of ground concentration of an admixture.
where: [Q.sub.i]--intensity of pressure bump of i-th source.
However, the account in an aerologic oilpainting of harmful pressure bumps of the chemical enterprises in this work is not planned, as it will demand the big massive of the complementary information.
Depending on the location of cooling towers, their type and power, a lay of land and meteorological conditions pressure bumps of drop moisture in the form of an aerosol from a cooling tower can render the determined negative environmental impact.
Interaction of harmful pressure bumps with steam-air plumes from cooling towers.
Sources of harmful pressure bumps at the enterprises of an oil-and-gas complex usually are torches and chimneys.
Groups ventilatory section and single, and also tower cooling towers in aggregate with chimneys and other sources of harmful pressure bumps, being concentrated in the bounded territory of an industrial platform of the enterprise it is possible in plotting scale of a surrounding atmosphere, to esteem as peephole point sources.
As a result of interplay of a steam-air plume with pressure bumps of harmful matters of the chemical productions which have been laid out in a zone of propagation of a plume, namely in radius of 2-10 km, under the determined meteorological conditions there is an odds of fallout on soil of the pointed harmful matters.
