TrayHeart 4.7 Release
TrayHeart 4.7 Release
We are happy to introduce the new version 4.7 of TrayHeart with many new features and functions.
The list below shows some highlights. In the user area you can download the version history with a detailed description of the new features.
Multiple column configurations within a file
Up to the last version of TrayHeart there was one column design per file. You were able to compare and calculate several load scenarios for this column design by different cases, but all belonged to a certain column design.
To compare multiple column configurations within a file (e.g. for as-built vs. optimized design; or for comparing different designs from suppliers; or for checking effects on fouling/corrosion), we have equipped TrayHeart with new options for handling multiple column configurations within a file.
Additional profile graphs
Up to version 4.6 there were 3 profile graphs available: Stream profile graph, pressure drop curve and flooding factor curve. By this you can analyze the hydraulic behavior of a column.
For more details, we have implemented two further profile graphs on the main result screen: A „Level profile“ and a „Relative parameter profile“. In each of these graphs, important design parameters can be displayed.
Column inclination evaluation
There are various problems resulting in a poor level of an active area of a tray:
- Poor-leveled support rings
- Poor-leveled outlet weir
- Poor-leveled column
- Pressure surge deformation of active area
- Overloaded panels, resulting in sagging
- Wind load to the column shell resulting in an inclination
By this, the thickness of the two-phase layer is not the same on the active area and therefore the conditions for the gas flow are no longer uniform: A gas flow passing through a thin layer suffers a lower pressure loss than passing through a thicker layer.
Accordingly, more gas flows through at the point with the thinner layer until the pressure drop is the same again for all areas. This results in gas maldistribution. In the worst case, gas will not flow through a section of the active area at all.
We added a tool in TrayHeart to quantify those effects. Taking into account the column dimensions and the tray design (flow passes, flow path length, weir dimensions, …) gas maldistribution effects are calculated.
Other functions and features
There are many other functions and features: Ladder-type intake, one and three spray nozzle distributors, multi-flow-lane design of Thormann-type tunnel designs, weir ring designs for piped downcomers, import of ChemSep files, overall checks for column profiles, new models, new database entries, …
