    摘要: In a batch process in which fluid is contacted with solid particles in a vessel and withdrawn therefrom through a passageway, the passageway is provided with filtering means to prevent solid particles from escaping. The next batch of feed is introduced into the vessel through the same passageway causing displacement of the particles retained by the filtering means and carrying them back into the contacting zone of the vessel.
