Max take-off frequency per runway

Hi does anyone know the highest take-off and landing frequencies you can have per runway?

If stands can process planes every 4.5 hours (270 minutes), then in theory using 54 stands you can have a plane taking off every five minutes. Is it practical to have all these flights land on one runway, and take-off from another runway? Or would more runways be required?

Well, might want to look at that for a second :thinking::
