I have a question regarding absorption stability
Thread Content
During absorption stabilization, I’m not sure if there is a difference between desorption, desolvation, and resolution It seems the first two are the same thing, but what about the third?
Desorption and desolvation are the same; they are processes by which the adsorbed substance is removed from the surface of the adsorbent, and can be carried out through methods such as heating, reducing pressure, or purging. The analysis is unclear.
During absorption stabilization, desorption refers to the separation of the adsorbed substance from the adsorbent; generally, this involves a significant amount of material being separated； In the case of desorption, there is an additional 10% degree of separation, as well as a separation that occurs by releasing the adsorbed substance; generally, this process requires the application of external force ； Analysis specifically refers to the process of the adsorbate detaching from the adsorbent surface. There are differences among the three, but they are not significant; the first two represent more macroscopic descriptions of processes, while the third refers specifically to a detailed process of reflection.
Explanation: In catalytic cracking, crude gasoline is used as an absorbent to absorb as much of the heavier components in the gaseous phase (the rich gas), such as propylene, etc. As a result, what remains in the gaseous phase is mainly dry gas and hydrogen, etc. During the separation process, a heat source is used to heat the mixture, causing the crude gasoline to separate from it. This is the concept parsed in the process
Pages P171–P181 in the first volume of the Practical Special Topic Design Manual for Chemical Engineering are dedicated to absorption stabilization systems; those who are not familiar with this topic can take a look as it will be informative.
Sir, is there an electronic version of this book? Want to share! ;P
The furnace tubes in the high-temperature superheating section of industrial boilers often burst. What could be the reasons? Thank you!
Thank you for your detailed explanation; I’ve learned a lot from it!
