During production of printed materials the ambient air in the working area absorbs a lot of gaseous pollutants (contaminants) that have so-called `paint smell` - solvents of various kinds (alcohols, ketones, aromatic hydrocarbons, etc.). The presence of these substances in the working area ambient air produces harmful effect at least on the personnel. In addition, solvent emission into the air is penalized in compliance with current regulation.
One of the problems arising in wood processing and production of popular materials based on wood, such as plywood, wood-chip and wood-fiber materials (chipboard, hardboard, OSB) is removing harmful substances from the air. Emissions from these industries are characterized primarily by the presence of phenol and formaldehyde, and the level of discharge is significant, up to 100 000 m3/hour of contaminated air.
Manufacturing and processing food products produces emissions that must be treated. Firstly, emissions produced by heat-treating raw materials should be treated, in particular carboxylic acids, formaldehyde and acetone.
PLAZKAT Aero systems are used to treat emissions from motor and railroad vehicles. It has been found that exhaust gases from internal combustion engines (ICE) contain over 250 ingredients. Major components include carbon oxides, nitrogen oxides and hydrocarbons.
PLAZKAT Aero units are used to neutralize bad smells from waste treatment facilities, caused by the presence of sulfur and nitrogen compounds - hydrogen sulfide, mercaptans, and ammonia. Urban waste treatment facilities, local waste treatment systems in factories, pumping stations in waste water treatment systems are characterized by a strong smell of sulfur and nitric compounds.
In connection with treatment of emissions from the pharmaceutical industry it is neccessary to observe stringent restrictions on biological air contamination. The use of PLAZKAT units in the pharmaceutical industry not only allows effective treatment of biological contaminants in the air, but also of harmful impurities.
In connection with the production and processing of polymer materials (manufacturing and cutting plastic film, workingwith thermoplastics, laser cutting plastic) it is necessary to remove pollutants from the ambient air in the working area (e.g.contaminants). In this environment it is usual to install systems for removing organic substances, mainly carboxylic acids, ketones, styrene, hydrocarbons С1-С10 etc.
Today, the reduction of atmospheric emissions produced by the gas processing and petrochemical industries is an acute problem. The most widely used technique of exhaust gas treatment comprises complete burning, even though this method does not provide an adequate degree of treatment. Therefore, in this case PLAZKAT systems are a more effective solution for removing aromatic hydrocarbon from the emissions.
Metal casting and heat treatment processes are associated with harmful gaseous emissions into the atmosphere which include substances such as carbon monoxide, nitrous oxides, oil vapors and sulfur dioxide.
It is known that 100% of the solvents contained in paints are released into the atmosphere when paint is applied and then dried. In addition, when paint is applied in a paint spray booth, about 30%of the sprayed paint is released into ambient air.
Plasma catalytic treatment is desirable in the following processes used in the chemical industry: basic organic synthesis, production of artificial fibers and manufacture of mineral fertilizers.
