“…After that, the purified gas leaves the apparatus through the outlet nozzle. Settling out of small particles on the surfaces of the arc-shaped elements can also be a result of electrostatic forces, Brownian motion, inertial forces and the combination of all these factors [15][16][17][18]. The finely dispersed particles settle on the surfaces of the elements, which are periodically cleaned by means of special equipment (Fig.…”

This paper includes the description of a separator, developed by the authors for the gas flow purification from the finely dispersed particles. The authors also studied the influence of the separator dimensions and the dusty gas flow rate on the degree of its purification from the finely dispersed particles, as well as on the change in the hydraulic resistance of this apparatus. This paper also shows that the main forces that make the greatest contribution to the purification of the gas flow from the finely dispersed particles are centrifugal and inertial. Moreover, the dependencies of the purification efficiency on the Stokes numbers are shown in this paper. The authors studied the change in the hydraulic resistance coefficient of this apparatus from the Reynolds numbers as well.

“…A certain number of technical activities in environment well known ways decreasing volumes of harmful emissions of GFS into the atmosphere were described in literature, for example, [3,4]. In [11,12] cleaning device [13] for the aspiration schemes to reduce dust and gaseous emissions. It was proposed to use this liquid device as absorber for trapping gas.…”

The issue of this article is improving the ecological safety of gas filling stations (GFS) that are placed within urban areas and the boundary of the sanitary protection zone. It has been determined that the main share of GFS' emissions is produced by petroleum products, especially when reservoirs are filled fuel storage tanks. It was proposed the way for reduce emissions from fuel storage tanks during the filled operation. It could be reach by applying of an apparatus for the absorption of gasoline vapors from GFS' emissions into the atmosphere. There presented the results by proposed devices for cleaning emissions GFS' in this article. It was obtained the regressions of recovery effectiveness for the improving design devices by mathematical processing for fuel oil and kerosene as work sorbent liquids. There are suggesting some approaches for modeling and engineering calculation's ways of such absorbing recovery devices in this article. The research results were implemented for design of full scale industrial set up that was installed and successful tested in one aspiration schemes GFS situated in Stavropol region of Russia. It was showed the reliability of the proposed device for practical use in the structure of the city municipal economy.

“…As of today, a large number of various devices with high efficiency of dedusting the gas flows were developed, for example, various modifications of inertial dust collectors, such as dust-collecting chambers, cyclones, etc. [9][10][11][12][13][14][15][16][17][18]. Easy operation, high reliability and ability to operate at high temperatures and pressures are important advantages of these devices.…”

The article deals with the problem of increasing the efficiency of dedusting the gas flow from the finely dispersed particles smaller than 10 μm. In order to solve this problem, a design of centrifugal separator with coaxially arranged pipes is proposed. The described principle of operation includes the large values of centrifugal forces, which take place inside the device when the flow is swirled, and these forces throw the finely dispersed particles to the walls of device. This scientific paper shows a numerical simulation of gas flow dedusting process by means of ANSYS Fluent software package. The efficiency of dedusting the gas from the finely dispersed particles of up to 10 μm in the device is on average within the range of 53.8–76.7%. The exponential function, describing the changes in the pressure loss from the input gas rate, is obtained. In the course of studies, it was found that the pressure loss in the device is not more than 800 Pa at the input gas rate from 3 to 19 m/s.
