Principles of catalytic absorption towers and reabsorption towers
Thread Content
Many catalytic process engineers nowadays believe that the absorption principles in catalytic absorbers and reabsorbers are based on the principle of similarity and compatibility; I, however, think it is related to the vapor pressure of the solute, following Henry’s law. Please ask some expert for advice! ! !
Frightened, I quickly searched on Baidu to find out what Henry’s law is
I still think it’s easier to understand the concept of \"like dissolves like\"; I’ll wait for experts in this field to explain it so we can learn together* – there’s not much to learn in school anyway
That’s the principle behind it; it also involves the concept of saturation! In other words, the greater the concentration difference between the two, the better the relative solubility!
Saturation is not mentioned because the absorbent used in the absorption tower has a composition and molecular weight similar to those of the substance to be absorbed, and the principle of like dissolves like can be applied uniformly; moreover, the concentration gradients vary across different trays within the tower
