| Abstract: | The effects of different outlet weir heights on the tray efficiency and the overall column efficiency of cross-type valve trays were studied in a column with diameter of 750 mm in cyclohexane-heptane system under the conditions of full reflux and atmospheric pressure.Its overall column efficiency was also compared with that of F1 valve trays.The experimental results show that the tray efficiency can be enhanced by 5%-12% with the increase of outlet weir height from 30 mm to 50 mm in the normal operation.At ... |
