The section efficiency is calculated based on fundamental mass-transfer considerations, including the approach to equilibrium both locally on the tray (point efficiency) and on the tray as a whole (tray efficiency). The conventional method of designing trays (2)employs Murphree’s definition of … See more If there are any hidden ties between the O’Connell and traditional methods for calculating tray efficiency, the approaches should produce similar results and the following approximation must hold: It is not obvious why … See more To establish the conditions under which the results of O’Connell’s correlation and the traditional model can agree, the stripping factor (λ), … See more The derived simplified theoretical model is expected to more accurately predict section efficiencies, albeit with increasing complexity. Therefore, a simple modification to … See more Combining Eq. 10 with Eq. 7 yields almost identical section efficiencies for a given value of the stripping factor and its reciprocal. Figure 4 … See more WebBubble-cap trays require extensive labor and more materials to produce than extruded fixed valves, and therefore are significantly more expensive (by a factor of 2–3). Although …
