Abstract.One of the methods of solving the problem of improvement of heat-mass efficiency of thermal deaerators of TPSs is application of jetfilm contact devices for interaction of vapor and liquid flows. The design of these devices has been studied. Estimate calculations of hydraulic resistance have been carried out. We have obtained the equation for calculation of resistance coefficient, depending on the height of element of contact device.

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.

“…The nozzle and plate contact devices are completely different in principle of operation, and their suitability for specific separation processes is different. The main difference is that in the packed column continuous contact is made between the gas and the liquid, while stepwise contact occurs in the tray [10][11][12][13][14][15][16][17][18][19].…”

The article is devoted to the study of methods for modeling the operation of rectification columns using the HYSIS application software package. Such studies are very important not only for design, but also for the functioning of existing industries. The article proposes to use for combining nozzle devices in the concentration part of the column, and plate-shaped structures in the distant part of the column for more efficient and stable operation of distillation columns. To determine the hydrodynamic parameters of the operation of distillation column, a technique of determining the range of stable loads and the position of the operating point inside or outside the range of stable loads was taken. A column model was constructed using the HYSYS software package for separating gas mixtures with various contact devices: sieve trays, Rashig ring nozzles. Experiments for the same type and combined contact devices were carried out and their comparison was carried out in terms of hydraulic calculation and operating range. As a result of experiments with the use of the HYSYS software package, it was shown that the combined arrangement of contact devices can provide a stable hydraulic mode, in contrast to the use of similar contact devices.
