The vapor exiting the condenser contains the most volatile components, while the least volatile components exit through the reboiler in the liquid stream. Equipment Design After the feed mixture enters the column, which is demonstrated by the green arrows in the animation below, liquid flows down the column and across the trays in either crossflow or countercurrent flow.
