What is the tower design procedure?
Thread Content
In tower design, what aspects need to be designed by the process engineering team, and what aspects need to be designed by the equipment engineering team?
The process engineering team is responsible for designing the inner diameter of the tower, the openings in the tower, their locations, the diameter of the pipes at those openings, the number of tray layers, the structure of the trays, their open area ratio, the spacing between trays, the size and location of access holes, the total height of the tower, as well as the dimensions of the downcomers, overflow weirs, and overflow trays. The professional equipment designers determine the wall thickness, skirt, lifting methods, etc. of the tower, and then design it based on the process requirements.
1. Organize the process parameters (convert them to appropriate and uniform units for use). 2. Estimate the gas velocity in the empty tower; determine the tower diameter and round it off as necessary. 3. Determine the number of theoretical plates, the type of plates, the design of the downcomer, the overflow weir, and other structural elements within the tower. 4. Calculate the pressure drop across the tower. 5. Determine the dimensions and locations of various openings (such as those for material inlet and outlet). 6. Design the piping system for the tower equipment
I am extremely grateful to all of you for your explanations, which have been extremely helpful to me. However, there is one thing I still don’t understand: since there are specialized software programs for equipment design, such as SW6, are there any dedicated software programs for process design to carry out such tasks? Should we still use manual calculation?
First calculate the inner diameter, then the unit height, packing height, and accessories
Aspen Plus is said to be of an academic style, and it’s not easy to learn
It includes everything from the manufacturing process to the verification of mechanical strength as specified in jb4710-2005
