Vibration fluidization and compaction of thermal insulation

Industrial Applications of Fluidized Beds

“…Figure 7 illustrates some of the designs reported in the open literature. Figure 7(a), adapted from Avery and Tracey [9], shows the multistage process developed by engineers at Courtaulds Ltd. for the recovery of dilute carbon disulfide (~0.1%) from air. To reduce the power consumption needed to handle the very large volume of air to be treated, each stage is very shallow (5-8 cm) and rests on a simple perforated steel plate.…”

“…The initial particle size of the carbon is 2-3 mm, but with continuous attrition and makeup the size reduces to 0.1-3 mm after a few months, according to Avery and Tracey [9]. The circulation rate of carbon around the plant is controlled by variable orifice valves at two locations, as shown in Fig.…”
