Legend for Table 11.2 Comments

Data show a continuous dedine of HETP with higher loads (see Fig. 8.166). This implies maldistribution at low liquid rate ( 2 gpm/ft ) also a possible wetting problem. The HETPs listed are within a turndown of 1,6 from the apparent loading point. 

High purity ( 96 percent) of nonaqueous component in column overhead. 

Where two values are shown under column diameter or column height, the ilrst describes the relevant dimension above the feed, the second describes the relevant dimension below the feed. 

Value reported under reflux ratio is mass vapor to liquid ratio.
