Comment. This calculation predicts that the column will flood, and that a larger diameter is required. As previously stated (Sec. 6.2.6), Fair's correlation tends to be conservative, especially at high pressure and liquid rate. If a conservative design is desired, column diameter should be expanded to 6.5 ft. In normal design, this type of result for the alternate check will signal a warning against reducing the diameter any further (say to 5.5 ft, as mentioned previously), and will also suggest that it would be beneficial to carry out a flooding check with a second alternative correlation. This will be performed using the Smith et al. correlation (Sec. 6.2.6).
