Methanol synthesis tower temperature branching
Thread Content
I am currently working on a methanol synthesis tower in which the temperature often fluctuates. I would like everyone to discuss the possible causes as well as ways to prevent and address this issue. . . . . . . . . . . . .
:handshake :handshake We have also encountered situations of single or double branching in the temperature of methanol. I believe it is necessary to analyze this from the following aspects: 1. It may be due to an excessively large tower diameter, which causes gas deviation. 2. It is necessary to check whether the carbon dioxide content in the gas is too high. 3. The upper temperature needs to be checked as it is too low. :handshake :handshake
Today, I found that the reasons for temperature splitting are roughly as follows: 1. Uneven catalyst loading, which results in excessive bed resistance and gas shunting; 2. Inadequate heating and reduction, leading to uneven reactions; 3. Short circuits in the cold pipes
Agree with the view from the third floor; generally, when the diameter of the tower is too large, this kind of situation tends to occur
The cut-off valve for the circulating gas in the cycle compressor failed to close properly in a timely manner, resulting in a sharp drop in pressure in the synthesis tower. The catalyst moved up and down, and the high level of carbon dioxide at the inlet caused branching in our bed layer.
