The Flow of Mixture Vapors in the Vacuum Column K101, Nominal and Reduced Capacity
Říha, Zdeněk
The report contains CFD results and description of the gas mixture flow in the bottom part of the vacuum column K101. There were solved two cases. Both cases had the same geometry. The difference between ones was in quantity of vapors on the inputs. The first case was calculated for the nominal quantity of vapors. The second case was calculated for reduced quantity (60% of nominal quantity) of vapors. Calculated results of above mentioned cases are placed in report´s enclosures 1 and 2.

CDF model of mixture gas flow in the vacuum column 12T-70102, revamp tower
Říha, Zdeněk
The report contains description of fluid flow for case with revamp tower of the column 12T -70102. Vapor flow was mainly calculated in the above mentioned geometry. In last iteration the liquid droplet (diameter 0,3mm) were injected into the geometry through the nozzle 12, see enclosure in the report. Introductory section of the enclosuere contains pictures with geometry and boundary conditions description, See figure G1. Then, slice plan follows, see figure G2. Next pictures show distribution of pressure and velocity on given slices. Pictures at the end of the enclosure show path-lines distribution and droplets particle traces distribution in the solved geometry.

CFD model of mixture gas flow in the vacuum column D-6501
Říha, Zdeněk
The report contains CFD results and description of the gas mixture flow in the vacuum column D-6501. Two rotationally opposite (swirl) input nozzles S1 and S2 (ID 0,835m) create main input of vapour into the vacuum column. There are two enhanced vapour horn (EVH) distributor, for given input nozzle (S1, S2) separately. Enhanced vapour horn makes redistribution of vapour leaded from above mentioned nozzles. There also is next input of vapor given by bottom striping section. The inner diameter of the column is 7,464m and solved domain has height c. 15m. Aim of the calculation is to show distribution of calculated variables (velocity, pressure, density, etc.) on given slices. Mainly, we would like to know if the distribution of velocity is sufficiently uniform at the input into the packing bed SECTION “B”.

CFD model of mixture gas flow in the vacuum column D-6501, adjusted EVH and tray
Říha, Zdeněk
The report contains CFD results and description of the gas mixture flow in the vacuum column D-6501 with adjusted internals against last calculated case, see [1]. Two rotationally opposite (swirl) input nozzles S1 and S2 (ID 0,835m) create main input of vapour into the vacuum column. There are two enhanced vapour horn (EVH) distributor, for given input nozzle (S1, S2) separately. Enhanced vapour horn makes redistribution of vapour leaded from above mentioned nozzles. There also is next input of vapor given by bottom striping section. The inner diameter of the column is 7,464m and solved domain has height c. 15m.
