ABSTRACT
The capture of oil and petroleum product vapors using pressure absorption is one of the promising methods for reducing their losses, which simultaneously ensures a reduction in environmental pollution. In its simplest form, such a vapor recovery unit (URP) provides for the use of a liquid-gas ejector (LGE), a pump and a circulation-separation tank, which makes it relatively low-capital-intensive and therefore attractive to consumers. Methods for calculating the characteristics of the HGE with a relatively high efficiency have been sufficiently developed to date. However, the methodology for determining the parameters of ejector URPS is not described in the literature. The purpose of the article is to develop a methodology for calculating ejector steam recovery units with a circulation-separation capacity. The paper provides a mathematical description of the problems of choosing a pump, determining the diameters of technological pipelines, choosing the height of the installation of a liquid-gas ejector, as well as determining the time period after which the low-volatile liquid in the installation circuit requires replacement. The pump is selected according to the pressure and supply found on the basis of the solution of the pressure balance equation compiled in relation to the calculation scheme given in the article. The peculiarity of its solution is the use of the method of hydraulic calculation of pipelines according to the recommended speeds, which made it possible to express friction losses without using pipe diameters in the calculation. Their determination is made further by the found flow rate of the working fluid and the recommended pumping speeds. The required pump head is determined based on the characteristics of the liquid-gas ejector and the pressure that must be provided at the outlet of the HGE. The frequency of replacement of a low-volatile liquid used as a working fluid is linked to the amount of evaporation losses, the degree of gasoline vapor capture and the permissible concentration of gasoline vapors in a low-volatile liquid. In general, a methodology for determining the parameters of ejector steam recovery units with a circulation-separation capacity is proposed.
KEYWORDS: losses of oil and petroleum products from evaporation, recovery, liquid-gas ejector, true gas content, circulation and separation capacity.

ABSTRACT
Based on data from the industrial application the article presents numerical study of the effectiveness of drag reduction agents in dependence on the operation mode of main oil pipeline: when pipeline looping is connected of and when Reynolds numbers and shear stresses are increasing of due to introducing additional pumps into operation. The results are obtained that combination application of the pipeline looping with the addition of an anti-turbulent agents leads to decreasing of the effectiveness of the anti-turbulent agent compared to the operation mode without looping. During the transition to more developed turbulent flow, the effectiveness of the anti-turbulent additive increases to a certain maximum value, and with a further increase of the flow velocity, shear stress and Reynolds number, it decreases.
KEYWORDS: drag reduction additive, operation mode, degradation of drag reduction additive, hydrodynamic drag.

ABSTRACT
Mathematical modeling of fluid flow modes through pipelines and leaks from them is well known and widely used for the development and application of leak detection systems. The adequacy of this model is of theoretical and practical value. However, as practice shows the standard leakage model leads to pressure trends, which may differ somewhat from the real ones. To adapt the classical model, amendments are proposed to bring the calculated pressure trends closer to the real. These amendments consist in the addition of dynamic components to the boundary conditions and also to the equations of motion and withdrawal.
KEYWORDS: Main oil pipeline, leak detection systems, pressure drop wave, wave front, wave tail, mathematical model, model adaptation.

ABSTRACT
The article proposes a method for increasing the corrosion resistance of welded joints made of carbon steels when irradiated with nanosecond laser pulses. An assessment of the corrosion resistance of modified surfaces of welded joints is given. The analysis of the microstructure of the surface of welded joints, which indicates pitting corrosion, is carried out. It has been found that laser-treated surfaces have improved anti-corrosion properties and have different degrees of corrosion protection depending on the type of nanorelief. It has been shown that the process of laser treatment makes it possible to purposefully change the surface morphology and physicochemical properties of steel with the formation of superhydrophobic surface and subsurface micro- and nanostructures.
KEYWORDS: corrosion, laser ablation, carbon steel, welded joints.

ABSTRACT
In the process of storage and transportation of oil and oil products, irreversible autocatalytic processes occur, leading to an increase in the content of moisture and mineral impurities in them. This, in turn, affects the change in the main physical and chemical parameters of petroleum products. This article presents the results of a study on assessing the impact of storing gasoline and diesel fuel in the conditions of the Krasnodar Territory of the Russian Federation on their standard quality indicators. It is determined that the deterioration of the quality of diesel fuel is more intense than the deterioration of the quality of gasoline. The water content and pour point are those indicators, the values of which after its storage have gone beyond the limits of parameters of regulatory documents. Particular attention was paid to the experimental determination and development of mathematical dependences of the influence of ambient temperature on the pressure of saturated vapors of gasoline and diesel fuel. The obtained research results can be used to establish evidence-based storage periods for gasoline and diesel fuel in the conditions of the South of Russia.
KEYWORDS: gasoline, diesel fuel, storage, moisture content, octane number, fractional analysis, saturated steam pressure.

ABSTRACT
A detailed justification is given for the need to introduce magnitude as a logarithmic function of the main parameter, eliminating the singularity of the probability distribution at point 0 for fractal objects, which include volcanic eruptions, earthquakes, etc. In an accessible form, the derivation of the basic formulas for the analysis of power-law distributions, which is the main method for describing fractal objects, is given. Applications of this methodology for practical volcanology are given. The main types of magnitudes in volcanology and volcanic seismology are described. Examples of volcanic eruptions of various explosive magnitudes (VEI) in Kamchatka are given. The Middle and Upper Pleistocene calderas in Kamchatka are shown, associated with the maximum possible eruptions with VEI = 7.
KEYWORDS: volcano, eruption, caldera, power-law probability distribution, magnitudes of volcanic eruptions.
