What is the volume change of the combined alkali mother liquor after absorbing ammonia?
Thread Content
When the second ammonia mother liquor absorbs ammonia, it will also absorb ammonia gas, carbon dioxide and water vapor produced by the distillation of the weak liquid. Will the absorption of these gases have a big impact on the volume of the ammonia mother liquor two? I hope sea friends will discuss this.
Let me give you a general overview of my situation. I don’t know the specific situation of your evaporated liquid distillation. Personally, I think it should have little impact on the size of the M2. Judging from the situation of the weak liquid distillation tower itself, the amount of gas coming out is relatively small. The main component is ammonia, and a small amount of water vapor, and the CO2 is even less. After M2 is absorbed, the volume will definitely increase, which will have a little impact on the FNH3 concentration of A2, but that is very small. In our case, only a small amount of M2 is used to absorb the gas from the weak liquid distillation (at the outlet of the M2 pump Adding a second line to regulate the absorption of dilute liquid distilled ammonia), on the contrary, has certain benefits for the entire production. The temperature of dilute liquid ammonia is high, which can increase the temperature of A2, which is beneficial to the production of soda ash. At the same time, M2 will reduce the solubility of NACL after absorbing ammonia, and dilute liquid ammonia contains a certain amount of water vapor, which is beneficial to reducing agglomeration. The above are personal opinions. If you have different opinions, please speak up and discuss.
After inhaling, the volume will increase, that's for sure. It is introduced in Soda Ash Engineering. But the impact is not big, just a few percent.
The volume will naturally increase as the temperature rises after absorbing ammonia.
