Question

  • In ARDS Process 3 reactors in series first one single catalyst bed, and the other two having 2 catalyst bed for each. Why the first reactor out let line size (3 in) is smaller than the size of the outlet lines for other reactors (4 in).

    The selection of line size will be driven by the volumetric flow.  Assuming there is addition of quench gas between the reactors, and between the beds of the 2nd reactor, the volume flow from the 2nd reactor will be higher than the first. You may also have some cracking occurring, increasing the vapour fraction and hence volumetric flow in the outlet of the 2nd reactor.
