Will catalysts be introduced into catalytic diesel?
Thread Content
I would like to ask whether catalyst powder from the catalytic unit may be carried into the catalytic diesel fed into the hydrogenation unit. Then does it cause blockages in the downstream devices?
Generally, catalytic diesel is hydrotreated at gas stations or in storage tanks. During this process, if the catalyst powder is not completely removed, it may be carried into the catalytic diesel. However, through repeated processes such as precipitation, filtration, and purification, the catalyst powder is completely removed. Therefore, catalyst powder is generally not carried into the catalytic diesel entering the hydrogenation unit. Even if residual catalyst powder is present, it will not cause blockages in downstream equipment, as modern refining technologies can effectively remove foreign substances and impurities. In short, no catalyst powder is introduced into the catalyzed diesel, nor will it cause problems such as blockages in downstream equipment; therefore, users can use it with confidence. .
Generally, no catalyst powder is added. If carrying it, it’s necessary to thoroughly investigate the issue of catalyst carryover. Since diesel is also being carried, one can imagine how much catalyst will end up in the trays below; this can easily lead to clogging of those trays.
You’re completely wrong – it’s not unrealistic at all. Before entering the hydrogenation process, particles larger than 25 microns need to be removed using backwashing equipment. It is recommended to add a dehydration and solid-removal step before backwashing, as this can reduce the frequency of backwashing required!
Hello, what exactly is this dewatering and solid-liquid separation? I’ve heard of it for the first time; please explain it, master
It is a swirl-type dewatering and solid-removal device
Directly supplied catalytic diesel can introduce fine particles of the catalyst.
