Assuming that the feed mixture is liquid at its boiling point (saturated liquid) determine … a) Calculate the flowrates (mol/hr) of the distillate and bottoms. b) Determine the theoretical number of trays and the feed tray number for the specified operation. WebA simple fractional distillation column is outlined in Figure 1. The column may be trayed or packed. The column consists of two sections, the rectification (or refining) section above the feed, the stripping section below the feed. Heat is supplied to the reboiler at the bottom of the column and removed in the condenser at the top of the column. dai-key ドレッサー
