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.

This paper presents and patents new profiled- and annular-channel tangential swirlers with 1.8–3 times less hydraulic drag coefficient compared to swirlers with straight channel walls at the same flow rate, respectively. The results of numerical simulation of the gas velocity and pressure profiles for tangential swirler channels of different structures are presented. The modelling was carried out with the help of OpenFOAM software using the k-ε turbulence model. It is found that the shape of the velocity profile at the channel inlet has a decisive influence on the swirler drag coefficient. The greatest contribution to the total drag coefficient of the tangential swirler is made by the pressure drop at the channel inlet compared to the pressure drop at the channel wall and the channel outlet. The experimental dependencies of the tangential swirlers’ drag coefficient on the Reynolds number with a gas criterion of 2000–20,000 and the following structural channel parameters: width 1, 2–9 mm, height 1, 5–10 mm, number 5–45 units, inclination angle 0–45° are presented. The experimental data were compared with the modelling calculations and the convergence of data was achieved. The generalized dependence for the measurement of the hydraulic drag coefficient of three types of tangential swirlers considering the effect made by the geometric parameters (flow rate, width and height of the channel, wall inclination angle) on the pressure drop has been determined; it can be useful at the unit design stage as it allows for reducing the calculation time of the swirler parameters.

“…A large quantity of industrial packingsis known and a lot of packings are offered to be used industrially [1][2][3][4][5][6][7][8][9][10][11][12][13], and the work aimed at the creation of new packings is still going on. Creation of new highly efficient packings is a difficult and time-consuming process that sometimes requires providing for necessary but colliding structural solutions [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19].…”

The article dwells on the method for summarizing experimental data on hydrodynamics of one-phase filtration flows through packed heat-and-mass exchange apparatuses differing in configuration. Summarizing is performed using a modified generalized equation. The described method simplifies the work with experimental bulk data, helps to compare the packed heat-and-mass exchange apparatuses, assess their energy performance and find the ways for their industrial implementation in heat-and mass exchange equipment.
