The difference between stripping tower and distillation tower
Thread Content
Stripping and gas stripping methods are used to remove dissolved gases and certain volatile substances from water. That is, the gas (carrier gas) is introduced into the water to fully contact each other, so that the dissolved gas and volatile substances in the water pass through the gas-liquid interface and transfer to the gas phase, thereby achieving the purpose of removing pollutants. Air or water vapor is commonly used as carrier gas. The former is called stripping and the latter is called stripping. Stripping towers are generally made like distillation towers! The question is what is the difference between it and the distillation tower? Because the feed for distillation is generally a heated gas-liquid mixture, but the feed for the stripper is liquid, I personally think there should be some differences at the feed port! I hope friends who know more about it can tell me!
The two are different. Distillation is more complicated than stripping. Distillation has several types of stripping section, rectification section, and bubble point feed. In addition, rectification has reboilers and so on. Stripping is where the gas is in contact with the stripping fluid. Anyway, there are many differences. I don’t know if I don’t understand what you mean.
Stripping towers generally have one gas feed and one liquid feed, and generally no reflux. The distillation tower must have reflux. Stripping tower is similar to absorption and desorption tower
2#wu* The anhai distillation column is obviously a feed, with reflux and reboiling. According to the principle of stripping, air is introduced at the bottom of the tower and liquid is placed at the top of the tower! There are similarities in their principles, but there are also big differences! So, what are the similarities and differences in construction, design, sampling, control, etc.? Are there other shapes for the stripper?
The stripping tower should be a distillation tower heated directly by steam.
