Methanol production from coke oven gas ； Converted position
Thread Content
Why are the ceramic balls smaller at the top and larger at the bottom in the converter, and what is their purpose???
Reply to 1# Fan Longfei: It serves to distribute the airflow and protect the catalyst. I am also looking for materials in this area; feel free to add me as a friend to discuss ways to improve it together.
The upper area is not a region with intense reactions; therefore, the gas flow rate should be reduced to increase the reaction time of the gas on the catalyst surface. This is precisely because the gaps between the small ceramic balls are small. After the reaction below is complete, large porcelain balls are placed to reduce resistance (relatively speaking). Personal opinion; I hope everyone can discuss it together
You all know these things; I need to study hard again
Reply to 3# Wind and rain aside: Basically, the small ceramic balls at the top are used to ensure even distribution of the gas, so that it can burn fully in the combustion chamber and provide the necessary heat for the conversion of vapor at the bottom (an endothermic reaction)； I still need advice on the lower part. Thank you
Think about the structure of your converter dome and you’ll understand.
The gas at the lower level expands, so large balls are used, primarily to increase production capacity
The methanol cycle machine is driven by a steam turbine; what safety devices are available?
What’s happening in the methanol industry? It is said that the industry is saturated; those who know more about this, please share their insights. Thank you!
Methanol production by oxygen-enriched combustion of coke oven gas. Fluids rise upward and fluids descend downward. Ceramic balls are chosen because they are high-temperature refractory materials. The reason for the smaller size at the top and larger size at the bottom is that the upper part contains air, while the lower part contains liquid. That’s all there is to it. As for the rest, you guys can figure it out yourselves.
No matter who says it, I’ll learn it first*. The upper balls aren’t there to ensure even distribution, right? Even gas distribution has little to do with the size of the balls
