The article is devoted to the issue of reducing energy costs in industrial separation processes in rectification plants. The article reviews the ways to increase energy efficiency and reduce the costs of resources in industrial separation processes, assesses the possibility of using a heat pump as a secondary energy recycler in industrial separation processes. Calculation and comparative analysis of closed and open circuits for switching the heat pump into industrial separation facilities are presented. As a result of the analysis of the data obtained, it can be concluded that when using the “rectification column-heat pump of a closed type” installation, the heat energy consumption in the form of heating steam is reduced by 20% compared to the traditional installation, with the “rectification column-heat pump of open type” energy consumption is reduced by 35%. Also, the overall dimensions of the column itself are reduced, hence, the design becomes less metal-consuming, capital costs are reduced. The feasibility study of the option of switching the heat pump into industrial separation processes is given.

Intensification of heat transfer processes is an important and relevant task, and one way to solve it is the use of liquids with various nanoparticles, called “nanofluids.” Therefore, an experimental study of the convective heat transfer of nanodiamonds suspensions in a circular straight pipe was carried out in this paper. Ethylene glycol was used as the base liquid. The concentration of nanoparticles ranged from 0.25 vol.% to 2 vol.%. The Reynolds numbers varied from 5 to 100. The values of the viscosity and the thermal conductivity coefficients of the resulting nanofluids were also measured experimentally. It was found as a result of these measurements, that the dependence of the thermal conductivity on the concentration of nanoparticles is described by the Maxwell equation. The dependence of the nanofluids viscosity coefficient on the nanoparticles concentration was significantly differ from the Einstein equation, it was much higher. It was found as a result of experimental studies of convective heat transfer, that as the concentration of nanoparticles increases, the heat transfer coefficient also increases, and for a maximum concentration, it was 15% higher then for the base fluid.

The article proposes the software implementation of precise controllers in steam boiler control system. The practical significance of the study consists in the development of a step-time algorithm for the fuzzification of continuous physical quantities of the boiler process and the control flow-chart of a steam boiler with variable coefficients. The flow-chart for regulating the combustion and vaporization process is based on the system of production rules of two-valued logic. The indicators of quality and energy efficiency of a steam boiler automatic control with precise controllers using precise term sets are presented. A 3-D model for controlling the combustion and vaporization process in a steam boiler was developed in the fuzzyTech environment. The surface analysis of the constructed control model in the graphical shell of fuzzyTech on the basis of production rules is presented. The article is addressed to the teachers of technical disciplines in a university, as well as to postgraduate students.

This paper describes the results of comparing the lightning registration on the Kola Peninsula through single long-range lightning detector and lightning detection network of various manufacturers. The features of the considered lightning detection network are shown when lightning is detected in a given region. The comparative illustrations of discharges from two systems for some days with different thunderstorm activity are given. The similarity of the lightning discharges distribution is shown. Studies show that a large number of lightning detectors in a lightning network considerable improve the accuracy of determining the location of lightning. At the same time, a multidetector network, unlike a single lightning detector, does not determine the lightning polarity. Therefore the experiment revealing reliability of lightning discharge polarity determination has been made. This result allows uniting the systems that provides a basis for lightning detection development in Kola region.

The article is devoted to the development of a parameter control device for a medium voltage (MV) distribution electrical network. The classification of existing MV network control devices is given. Their advantages and disadvantages have been noted. The solid-state voltage regulator (SSVR) developed by the authors is simple and versatile. The design of the SSVR is presented and the network parameter regulating principle is described. The main attention is paid to the effects that can be achieved thanks to the SSVR. Adjusting the amplitude and phase angle of the voltage at the SSVR output allows controlling the active and reactive power flows, increasing the transmission line capacity, reducing the electrical losses in the network, ensuring the power system stable operation, etc. Options for the SSVR installation locations have been considered.

The technology of measurement and control of geometric parameters of large-sized parts in heavy and transport engineering, in power engineering, etc. is considered in this paper. It is based on the results of measuring the radial and axial run-out of the surfaces of the part and the subsequent processing of this primary measurement information, without requiring the accuracy of the output base. This can be comprehended by bringing the results of radial and axial run-out measurement to the virtual output datum - to the virtual datum axis, which is a straight line passing through the centroids of points of instantaneous rotation axes in sections of two rings mounted on the end face surfaces of the part approximately coaxial to its geometric axis.

This article provides a mathematical model of mass transfer taking place in the active zone of the diesel fuel hydrotreating reactor. It provides an additional insight into behaviour of physico-chemical process as the mathematical apparatus which was used to write this model completely interprets all subtleties of the proceeding process. Also it describes the necessity of combining thermal conductivity and diffusion equations into one model to ensure the most exact calculations of the heat-producing system and to form key parameters controlling system of the installation based on this model. In addition, the research considers analogy between process of filtering and process of efflux of diesel fuel through the layer of porous catalyst. Also, remember, that the medium consisting of mutually soluble chemically active components is exposed to filtering. The difference of homogeneous media from the complex heterogeneous substance considered in this case is in the presence of numerous interphase boundaries at the microlevel. At the same time each constituent phase occupies only a part of elementary volume of the saturated porous medium. Thus, in this paper the process of diesel fuel hydrotreating is considered as a combination of mass-exchanging, thermodynamic and filtrational processes. The cause of this point is that nowadays in literature the hydrotreating process is described mostly as heat-exchange, and the mass exchange is reported in the field of physical chemistry to describe the process kinetics. The article provides an addition to the existing diesel fuel hydrotreating reactor model that represents the description of thermal processes occurring in the active zone of the reactor [1]. This scientific research will help further understand problems of control of the object key parameters in detail [2], and further - to improve the process by transforming its mathematical description.
