WebFeb 2, 2015 · When this is the situation, the bottom product cannot be used for either composition or level control and it will be necessary to use the column feed flow to control the level. Feed flow could also be used in the case of a very small bottom product flow, but it is uncommon for the feed flow to be available to manipulate with the column controls. WebApr 6, 2024 · Generally, the feed tray should be located near the top of the column in order to maximize the separation efficiency. A higher feed tray location increases the reflux ratio, providing more stages for the vapor-liquid separation process, resulting in a higher quality of top and bottom products.
