Webthermodynamic efficiency while the rest of the works developed expressions to calculate thermodynamic efficiency and have applied them to a new problem of optimal control: Maximum thermodynamic efficiency. 2. Description of the process For this study we used a conventional batch distillation column consisting of: x Reboiler x Tray column http://blog.chemstations.com/
WebStep 5. Determine Actual Number of Trays This is determined by taking the quotient of the number of theoretical trays to the tray efficiency. Typical values for tray efficiency range from 0.5 to 0.7 (Douglas, 1988). These values depend on the type of trays being used, as well as the internal liquid and vapor flow rates.

WebTrays are the most common contactor in use. What are the functions expected of tray contac-tors in the tower? Figure 5 depicts a single tray contactor in a distillation tower and shows the primary functions desired: - Mixing rising vapor with a falling fluid. - Allow for separation after mixing. - Provide path for liquid to proceed down the tower.
