What causes foaming inside the degassing tower and fluctuations in pressure difference? How to solve it? Thank you! ! ! !
Why isn’t anyone helping me? It’s severely restricting production; I would appreciate it if experts could offer some guidance
Where is the original poster from? Could you provide contact information? Can we communicate over the phone? If it’s convenient, you can call me in the evening; my phone number is 18729679199. Alternatively, you can send me an email with detailed information on the operation of your distillation tower, and I’ll help analyze the reasons.
Is the shift tower used for MDEA or liquid decarburization using substances like propylene? If it’s liquid decarburization, then it’s quite normal
Is the shift tower used for MDEA or liquid decarburization using substances like propylene? If it’s liquid decarburization, then it’s quite normal. I used to encounter such problems frequently.
It’s best to clarify the detailed conditions of the equipment and processes; otherwise, it’s difficult to provide advice. Generally speaking, the solution is the most likely culprit
After decarburization, it should not affect the denitration process. The operating pressure for denitration is 3.3 MPa; the tower is 45 m high and has a diameter of 3600 mm. It consists of three sections of packing, each 10 m high, with a tray distributor in each section. The circulation rate is 330 m3/h, while the gas processing capacity is 120,000 Nm3/h. During operation, there is an unexplained increase in pressure difference; adding antifoam agents or salad oil reduces this pressure difference, and sometimes using clear liquid also helps.
There are too many impurities in the solution; you can try using an appropriate amount of liquid. What is the method for desulfurization?
I’ve used both NDC and tannin alum, and this problem has occurred with both of them; it’s really annoying. . . :Q:(:L
Could you provide the most recent solution analysis? What are your desulfurization pressure and flow rate? How is the oil added? How much sulfur is imported?
This phenomenon has also occurred in our factory; it is mainly due to poor regeneration efficiency, which results in weak desulfurization capacity and an inability to remove sulfur. Our factory’s final improvement measure was to install a new change-and-regeneration tank, maintain the change-and-regeneration temperature, and increase the amount of regeneration air; the results have improved significantly compared to before. In a situation like the owner’s, the production system should be adjusted to reduce its capacity, thereby lowering the volume of liquid that circulates. If no such adjustment is made, the circulation volume will have to increase, and given the poor quality of the solution, this can lead to a vicious cycle, resulting in liquid buildup and the solution clogging the valves.
