Relationship between various parameters in the amine solution regeneration tower
Thread Content
Let’s discuss the relationships between the parameters of the amine liquid regeneration tower (bottom and top of the tower, temperature and pressure, reflux rate, steam flow rate, etc.) And the accidents that could result!
The temperature at the bottom of the tower is 113 degrees, while it ranges from 100 to 105 degrees at the top. The pressure at the top of the tower is 0.08 MPA; the flow rate of reflux is 0.2 T/H, and the steam flow rate is 1.25 T/H. The processing capacity is 15 T/H. There have been many accidents – in my experience, the most common issue was the inability to send acidic gases out of the system. A particularly serious accident occurred when the amine solution in the reboiler at the bottom of the tower could not circulate properly. Another issue was that the pressure in the rich liquid degassing tank was lower than that in the raw liquid tower, which led to gas backflow from the amine regeneration tower into the rich liquid tank, causing a water hammer accident. One of the later accidents was very severe; once, the entire framework started shaking, which was really scary··
The temperature at the bottom of the tower is 120–123 degrees, while it ranges from 100 to 105 degrees at the top of the tower. The pressure at the top of the tower is 0.09–0.105 MPA. The reflux rate is 1.2 T/H, and the steam flow rate is 3.5–4.5 T/H. The processing capacity is 46 T/H. Steam cannot be supplied to the reboiler at the bottom of the tower when the liquid level in the regeneration tower is below 50%.
Temperature: 120–125 degrees at the bottom of the tower, and between 110 and 120 degrees at the top. Pressure: 0.07–0.10 MPA at the top of the tower. Flow rate of recycled material: 2–3 T/H; steam flow rate: 5–7 T/H. Processing capacity: 40 T/H. The regeneration tower contains oil, and the sulfur production unit yields black sulfur. The reactor overheats and cannot be controlled; the catalyst is damaged. It’s frustrating – after working hard for several days, I still end up getting punished
The temperature at the bottom of the tower is between 120 and 123 degrees, while it ranges from 100 to 105 degrees at the top of the tower. The pressure at the top of the tower is 0.08 to 0.09 MPA. The flow rate of the return stream is 3–4 T/H, and the steam flow rate is 8–10 T/H. The processing capacity is 80 T/H. If the temperature is too low, the lean liquid often fails to meet the required standards; on the other hand, if the temperature is too high, it can cause damage to the tower! There’s still some time left; the pressure difference inside the tower is very high, so it’s impossible to push water through the tower! It’s probably because the tray is blocked by coke powder!
The temperature at the bottom of the tower is 119–120 degrees, while it ranges from 95 to 105 degrees at the top of the tower. The pressure at the top of the tower is 0.07–0.08 MPA. The flow rate of the return stream is 3–4 tons, and the steam flow rate is 35–45 tons. The processing capacity is 500 tons. The problem I encountered was tower flooding, inadequate regeneration of the amine solution, and foaming of the amine solution!
I also need information in this area. What are the parameters for the regeneration of ethanolamine after it absorbs carbon dioxide? I’m not sure what kind of amine is meant by the amine solution here
It’s usually about managing the tower; as long as the temperature at the bottom of the tower and the pressures at the top of the tower as well as in the flash tank are under control, then everything will be fine
The temperature at the bottom of the tower must not exceed 125 degrees; it is best to keep it between 123 and 124 degrees
