As the title suggests, what is the amount of CO2 that can be absorbed by 1 part poor methanol, and how much CO2 can be absorbed by semi-poor methanol? Please share your opinions on how to determine the circulation volume in the end! ! Note: At 5.3 MPa and -64 degrees Celsius, synthetic ammonia
Also, what is your load? This is the most important, right?

Under fixed process conditions, the ability of methanol to absorb CO2 should remain constant. I’m not sure if you have conducted any tests on this; personally, I think the loading capacity depends not only on the production capacity of the facility but also on the absorption capacity of methanol – the greater the absorption capacity, the lower the circulation volume should be
How can it be calculated in such a general manner? It also has a great deal to do with the contact time between gas and liquid; otherwise, why would different types of trays be used in various devices? This requires calculation in reverse, that is, the calculation process followed by design firms during development；
Methanol washing is a physical process, and at present the physical properties provided by several patent holders are quite accurate. The specific circulation volume is determined by the patent holder. What others have given is just an estimated value, and it’s not very accurate. This is also closely related to the process flow – whether it is fully depleted liquid or partially depleted liquid, as well as factors such as temperature and water content – so it cannot be considered in a general manner.
