Fluidization vessel dimensions

Batch mixing using fluidization has been successfully employed in many industries. In this case there is practicaUy no limitation to vessel dimensions. 

To simulate a rectangular fluidized bed reactor the bed vessel dimensions have to be specified first. The vessel used for validation has a rectangular cross section [40]. The bed vessel was 0.3 (m) wide, 2.22 (m) high and 0.2 (m) deep. 

It is useful to provide some details of such a system that has been used successfully. Siegell et al. (1986) provide the following data vessel dimensions, z-direction, 69 cm, 7.6 cm wide composite adsorbent of 30 wt% alumina, 70 wt % stainless steel solids density, 1.7g/cm bed depth, 14 cm (y-direction) fluidizing air velocity (y-direction)... 

Fluid catalytic vessels are very large. Dimensions and performance of a medium capacity unit (about 50,000 BPSD, 60kg/sec) are shown with the figure. Other data for a reactor to handle 15,000 BPSD are a diameter of 25 ft and a height of 50 ft. Catalyst holdup and other data of such a reactor are given by Kraft, Ulrich, and O Connor (in Othmer (Ed.), Fluidization, Reinhold, New York, 1956) as follows ...
