Reactor Internal
Axial Flow (Down Flow) reactors are characterised by a down flow, from the top to the bottom of the reactor, that gives rise to chemical reactions between the reagent fluids coming into contact with the catalyst.
In a typical two-bed Axial Flow reactor configuration, the reagent fluid is distributed, by means of an inlet diffuser, over the underlying distributor tray. This tray has the function of evenly distributing the liquid over the underlying catalyst bed, supported by the catalyst support grid. Further, down the reactor there is the quench zone where the reagent fluid is cooled by means of gas injection and is then conveyed into a mixing chamber. From here, the liquid is distributed over the subsequent catalyst bed thanks to a distributor tray. The outlet collector positioned on the bottom of the reactor supports the lower catalyst bed and enables the reacted fluid to be conveyed outside the reactor.
