Patent ID: 7226535

Claim:
An expanded fluid bed system for use in treating a fluid by contacting the fluid with a solid phase media contained in the expanded fluid bed system which system comprises: a reactor chamber having an upper end and a lower end to contain the solid phase media and at least one fluid distribution means adapted to be rotated and to distribute and deliver the fluid to be treated among the particles of the medium, in a substantially uniform manner over a cross sectional area of the fluid bed system, which system is sized and dimensioned to operate under plug flow conditions, wherein said fluid distribution means includes a number of elongated tubes extending radially outwards towards an outer periphery of the reactor chamber; each elongated tube has penetrations extending from the inside of the tubes to the outside thereof so that the fluid to be treated flows through the internal of the tubes via the penetrations and to the medium, and wherein said tubes have cross sections shaped, so that generation of turbulence induced by said rotation is avoided, when the fluid distribution means is rotated with an rpm lower than 10.
