Column Diameter The vapour flow rate in either section of the column is obtained from the mass balance in kmol/hr. This is converted to m 3/s as follows: m3/s = (kmol/hr x mol wt.)/(density x 3600) From the continuity equation, q = va.

The question is posed as to why columns typically have a collection zone 10 m high (H) by 1 m in diameter (D). Three geometry dependent factors are considered: degree of mixing, Np; volumetric bias rate, B; and volumetric gas rate, G. Increasing H:D decreased Np and B, which improves performance but decreases G, which causes the column to approach overloading. Taking typical column operating ...

Column flotation devices were re-introduced for mineral processing in the late-1960's in Canada by Boutin and Wheeler (1967) at which time wash water addition to the froth was used to eliminate entrainment of hydrophilic materials to the float product. By the late-1980's column flotation had became a proven industrial
