Problem of stable tower top cold reflux
Thread Content
What effects will an excessively high or low cold reflux at the top of the stabilizer have on it? The temperature has dropped too rapidly recently, and the cold reflux temperature is too low – what impact will this have on the stabilizer column? I hope the experts can help me analyze it. Recently, this stabilizer tower has been producing little gas, and the saturation vapor pressure control is also substandard. Could these problems be related to the temperature dropping too quickly? ? I’m sorry; I can’t provide the relevant trend charts, so I can only describe it this way.
Without temperature, pressure, or anything else, how can you expect others to make a judgment? Is it fortune-telling?
The tower top pressure fluctuates between 0.85 and 0.89. The bottom temperature is between 164 and 165. When the top temperature does not exceed 50 degrees. Outdoor temperature: -8 degrees.
Raising the temperature of the feed material entering the tower is fundamental.
The analyzed bottom temperature is around 123.
The analyzed bottom temperature is around 123.
The low temperature at the bottom of the tower is causing carbon 4 to enter the gasoline, which increases the vapor pressure of the gasoline and results in a lower yield of liquefied gas at the top of the tower. Treatment: 1. Increase the bottom temperature of the tower. 2. Reduce the reflux volume and increase the reflux temperature. 3. Reduce the cooling water flow to the tower top cooler. 4. The top temperature should be around 55 degrees, which should be normal.
The pressure at the top of your tower is way too low; the gas can’t even be liquefied
How much do you control there? ?
