For the design of a naphthalene oil distillation column in a graduation project, how do I calculate the theoretical plates? Where can I find the saturated vapor pressure data needed to determine the temperatures at the top and bottom of the column? Thank you
Don’t let the question scare you, right! First, it is necessary to determine the composition of the materials. Then, using the principles of chemical engineering, value of a can be determined, the theoretical number of plates can be calculated, and the reflux ratio can be established. The actual number of plates can be found based on this, and considering that the efficiency of plate towers ranges from 0.4 to 0.6, the actual number of plates can be computed accordingly. In the case of packed towers, the packing height is calculated based on the equal plate height concept. Remember, it’s essential to use a safety factor; sometimes, this factor is quite high in industrial applications. If the saturated vapor pressure is not available, it needs to be calculated! If you have the software, you should be able to find the saturated vapor pressure of your material system. If these values do not appear during the calculation process, then your problem can be solved.
The approach is correct; currently, the bubble point method is being used to determine the top temperature of the tower. Should I look up the saturated vapor pressure in a physical chemistry handbook?
