One of the most effective ways to clean industrial gas emissions from dust is to filter them through a porous partition, in kind of which is the most often used a fabrics with different characteristics.
Filters which uses fabric as a flexible porous partition got the name “bag” due to the currently most common form of the frame in the form of a sleeve cylinder on which the fabric is stretched.
The main differences of fabric filters is in the method of regeneration, the design of filter elements (sleeves or cassettes), the number of sections in the filter, the modes of filtration and regeneration.
Bag filters are widely used in ferrous and nonferrous metallurgy, the chemical and petroleum industries, in the production of building materials and other industries.
The efficiency of dust collection in a bag filter depends on the dispersion of dust particles, the characteristics of the filter material, the method and mode of regeneration, the value of the specific gas and dust load, and the hydraulic resistance of the filter.

EGU-type electrostatic precipitators are designed for cleaning non-explosive process gases and aspiration air from 250 ° C to 330 ° C (according to the permissible temperature for the body frame) with a exhausting up to 10 kPa (1000 kgf /m²).
Electrostatic precipitators are used at the enterprises of the energy industry, ferrous and nonferrous metallurgy, the building materials industry and other sectors of the national economy.
Electrostatic precipitators are one- or two-section devices of rectangular shape with external thermal insulation consist of two to five or more electric fields installed sequential along the gas flow.
The core of the electrostatic precipitator consists of lamellar collecting electrodes and needle corona electrodes.

In modern industrial processes of dry dust collection in industrial, waste/exhaust gases are used bag fabric filters, which are capable of ensuring efficiency of > 99.9%, to meet environmental requirements. Moreover, their introduction involves less capital costs and smaller production mounting areas.
Sulfur oxides (SO2, and in smaller quantities SO3) is one of the largest and most difficult-to-clean air pollutants, and formed by their combination with water vapor acid (H2SO3 and H2SO4) cause the destruction of metal structures and building materials.
The greatest current interest is the use of technologies of gas desulphurization of dust air flow, which is capable of ensuring the effective (> 90%) binding of sulfur dioxide. The relevance of SO2 emission reduction is defined as the expansion of electricity generation using pulverized fuel and an increase in the share of coal in the balance of metallurgical industries.
One of the most effective methods is a method of semi-dry desulphurization, created and implemented based on the use of technological schemes and equipment manufactured by “BMZ “Progress”.
