I have a little confusion about inputs required from various departments for designing a column..
As per my understanding…
Process gives
1. TL-TL dimensions
2. BTL EL. if governed by process
3. Column diameter
4. No of trays required to achieve given degree of separation.
5. Nozzle elevations.
6. Type of tray.
Mechanical gives
1. Column shell and skirt thickness.
2. Tray thickness.
3. Tray support details , distributor details.
4. Tray spacing.
Piping gives
1. Tray and nozzle orientation.
2. Piping and platform Support cleat requirement.
3. BTL elevation if governed by pump NPSH or layout requirement.
Now my question is what factors in column design are governed by the vendor.
