Problems solved by technology

[0003] The technical solutions proposed by prior art 1 and prior art 2 are degassing towers. The current degassing towers are generally plate towers or packed towers using structured packing. Packed towers are selected as degassing process devices, which are suitable for rapid and instantaneous reactions. The process has the advantages of high specific surface area, high gas film mass transfer coefficient, and reduced gas phase flow pressure. The disadvantage is that the liquid storage volume is small and the liquid stays in the packed tower for a short time; the plate tower is selected as the rectification process device, which is suitable for In the fast and medium speed reaction process, it has the advantages of small liquid backmixing, uniform residence time, and large liquid film mass transfer coefficient. The disadvantages are complex structure, large gas phase pressure drop, and low corrosion resistance of tower internals.
In summary, due to the limitation of the liquid storage capacity of the packed tower and the plate tower, the processing capacity is small, the mass transfer efficiency is low, the pressure drop is large, and the operating flexibility is small
