MTO quench water centrifugal separation catalyst particles

But it is said that suspension separators tend to clog, and I’m wondering why not use a plate and frame filter? Today’s plate and frame filters can also operate continuously online. As far as I know, the catalyst in the quench water after the acrylonitrile fluidized bed is produced using a plate and frame filter press, with excellent results, and there are almost no particulates in the filtered water. MTO experts, let’s discuss this issue and pool our ideas.
Sir, which MTO plant are you working at?
How does a plate and frame filter separate gas from liquid?
There’s no chance to work on the MTO unit again; I’m writing a process simulation and investigation report on this topic. Since I don’t know much about it, let’s discuss it together. You should be at the MTO plant, right? Keep in touch!
That’s right; the liquid taken out from the bottom of the quench tower contains no gas phase, but it does contain a large number of fine catalyst particles
Currently, MTO units are also equipped with filters on the back side of the suspension separator; similar to plate-and-frame filters, these filters consist of a porous metal core, and during filtration, small solid particles form a filter cake on the inner wall of the filter element – such filters are known as LSI filters.
Why don’t you consider using vacuum evaporation technology? We have already conducted experiments on its application in the recovery process at Sinopec’s DMTO unit, and the results were very good. The manufacturers have already purchased the equipment; we can provide you with some technical documents if needed
I’m also interested. My email address is 15895635286@163.com
Send the information over so I can take a look; we’re facing a problem right now, let me check it
Please send the materials to tianjun@Chinajiutai.com! Thank you!
Can a plate and frame filter press solve high-temperature problems and sealing issues? 200-300 tons of quench water need to be processed per hour; it is at high temperature and contains some toxic and harmful volatile components. In such cases, can a plate and frame filter press meet the requirements?
