Reflux issues in distillation columns
Thread Content
The reflux ratio at the top of the distillation tower is 0.1751, and the temperature at the top is 106 degrees. When I set the reflux ratio to 0 and add the same material to the top of the tower without a top condenser, why is the temperature of the gas at the tower top different?
What material are you distilling? With such a low reflux rate, is the quality acceptable? Without convection, how do you maintain thermal balance? What is returned by the reflux is the need to achieve a balance between the cooling load and the heating load in the reactor tower, so as to ensure that the distillation process can be controlled. Friend, you need to understand the purpose of distillation.
It depends on whether the material flow rate and temperature you introduce are exactly the same as those of the reflux material
Is there a distillation column with a reflux ratio designed to be 0? You are amazing. :lol
What is distillation? What’s the point of distilling if there’s no reflux? At its simplest, it is a stripping tower with a feed plate leading to the bottom of the tower.
If the relative volatility of the two components in the incoming material is very high, is reflux still necessary? For example, concentrated ammonia water is distilled into liquid ammonia; ammonia water contains more than 50% ammonia.
It’s okay without reflux. I currently have a column where reflux is used almost entirely~~~~ Hehe, LZ, you should pay attention to whether the temperature of the medium undergoing normal reflux is the same as the temperature of the materials you add later, as well as their composition I don’t understand why you would do that: lol
By \"adding the same material to the tower top without tower top condensation,\" do you mean that no reflux is used, and only a stream of material at 106°C from the tower top is added? In that case, it becomes an absorption tower. At this point, if you haven’t implemented control of the tower top temperature, the tower might still function properly, but the tower top temperature will stabilize at a level higher than 106°C.
