“…The information technologies have found the greatest application in the field of mechanical engineering, and, in particular, chemical engineering, for calculation and simulation of processes and devices of chemical technology in order to find the optimal designengineering solutions [1][2][3][4][5][6][7][8]. It is difficult to imagine the development of modern chemical and petrochemical equipment without using such software systems such as ChemCAD, Ansys, SolidWorks, WinMachine, Compass 3D.…”

Theoretical aspects and experience of using the mathematical modeling and computerized simulation technology for solving the problems of installation and repair of process equipment of chemical and petrochemical industries are considered in this scientific paper. Computational model of restoring process to working condition of pipeline section has been developed. It is shown that if you use the developed model, then the labor-intensive installation activities, related to the repair works on heat and power networks of chemical industries, can be performed in a more efficient way.

“…Cooling towers are widely used for cooling circulating water in thermal power plants, as well as in petroleum refineries, chemical, and petrochemical plants [1,2]. Mechanical-draft cooling towers have a wide distribution by virtue of their energy efficiency, accessibility, and upgradability [3][4][5]. The cooling efficiency of these towers is highly sensitive to design and operating parameters (water temperature, gas and liquid flow rate, type of filler, and others) [6][7][8].…”

The paper deals with a pressing problem on the effective cooling of circulating water at industrial plants using the evaporative cooling towers. A new design of the cooling tower is developed that prevents the biological fouling of the equipment surfaces without the use of chemicals. The design of the filler unit with the inclined-corrugated plates and the metal mesh provides the advanced gas-liquid contact surface. An evaluation of the cooling efficiency of the inclined corrugated contact elements is performed by means of the volumetric coefficient values of heat transfer in the gas phase. From experimental data, it has been found that with increasing the wetting density, the volumetric heat transfer coefficients also increase at the same mean-flow air velocity. A comparative analysis of Merkel numbers for the developed filler unit with the existing analogs as the characteristic of cooling capacity indicated its superiority.

“…Operation efficiency of evaporation cooling apparatuses mainly depends on the operation efficiency of their contact packings . Papers [4,9,10,51] demonstrate that spraying units having fibre structure and having high values of porosity and specific surface are very promising in this sphere. An important feature of such fibre structure is that it is simple and easily manufactured [51][52][53].…”

The article presents the results of the experiments on fluid and gas dynamics through a layer of packing material S-Aisi304ε-0, 95 (ε=0, 95, σ=160m2/m3) suggested for use as packing blocks in small-size evaporation cooling apparatuses for industrial recirculated water. Experimentally confirmed effects are covered that prove the performance efficiency of wastes from metal-working machinery as packing materials for contact evaporation blocks. Results of mathematical modelling and engineering calculation of the main process parameters and dimensions for a small-size evaporation cooling apparatus for industrial recirculated water with use of contact blocks filled with the studied packing material are provided.
