How to unload the catalyst from the DN1000 methanol synthesis tower
Thread Content
This post is concluded by Free Fall_CSHI edited on 2019-6-14 20:09 How to unload the catalyst from the DN1000 methanol synthesis tower. Figure 1 shows that the internal parts have been lifted out. Figure 2 shows that the large internal parts have been covered and only the inner cover of the internal parts is left. Figure 3 shows the heat exchange tubes leaking out after removing the inner cover and wire mesh. Since the chemist does not have the structural diagram of the internal parts, I don’t know whether the heat exchange tubes are connected to the rear section of the internal parts. I don’t know how many beds of catalyst are there in the internal parts? How to remove it? Or can anyone in the forum provide the following structural diagram of the internal parts of this type of methanol synthesis tower? Thank you!
I couldn't wait for the answer, so I tried to lift the bottom of the inner parts with a crane, and the catalyst was completely removed from the opening of the inner parts. The key point is that if the removal is like this, then when loading, is it also loaded from the top heat exchanger? Can it be filled evenly?
Your synthesis tower is awesome. You can lift it out to replace the catalyst, but our equipment won't move.

I see that the internal parts of the synthesis tower are somewhat similar to Linda's. When filling the catalyst, be sure to seal the thin tube first and not install the catalyst.
This type should be Guochang Tower.
This should be an early medium-pressure combined alcohol device. The early single-tube baffle reactors pursued self-heating balance. Due to the small filling volume, the tower was basically lifted out and then discharged. See the picture. The diameter of the reactor should be 600mm. The tower (800mm may be smaller) has basically been eliminated. Due to energy consumption issues, most current combined alcohols use low-pressure methods, which can greatly save compressor power consumption.
