I have some doubts regarding the design of regenerative packed towers or high-gravity reactors
Thread Content
I have been studying the design of *regenerative hypergravity reactors recently, and I have a question. The various empirical formulas used in such design require various physical property parameters of both the gas and liquid phases, including density, viscosity, flow rates, pressure, etc. Since I am aiming to design a regeneration device rather than an absorption device, I only know the properties of the liquid phase at present; those of the gas phase are still unknown. I would like to ask how these physical property parameters related to the gas phase can be obtained. Is it necessary to first obtain equilibrium data? So which module should be used? Also, in the design process, when calculating the packing height, there is an equation that uses this capacity factor; Aspen can calculate this value? Hope someone can help!
For the design of regenerative packed towers or high-gravity reactors, physical properties of gas and liquid phases are required, such as density, viscosity, flow rate, pressure, etc. The gas-phase conditions can be obtained through experiments or simulation software. In terms of simulation software, chemical process simulation software such as Aspen Plus can be used for modeling and calculating gas-liquid phases. Usually, it is necessary to enter some initial conditions and data on the properties of the substances, then set the model parameters before calculations can be carried out. Regarding the calculation of the capacity factor, Aspen Plus can be used to solve it. The capacity factor is a constant used to describe the relationship between the packing height and flow rate. Typically, the capacity factor must be determined through experimental data, which is then input into simulation software for calculations. Aspen Plus offers many types of trays and packings; it is also possible to define custom packing types. By changing the packing height and other parameters, one can observe how the output results change, thereby optimizing the equipment design. .
Was the first simulation done using radfrac? Or other modules, in the case where the gas-phase parameters are unknown? Since radfrac requires the design of the tower’s inner diameter, it seems that this information isn’t available yet
