Process steam tower demister?
Thread Content
The process steam tower here has recently been equipped with an efficient demister; it is said to be intended to reduce the sodium ion content in the steam. I think the principle behind its installation is that the demister prevents gas-liquid entrainment, thereby reducing the water content in the steam and consequently lowering the sodium ion level. I’m not sure if this makes sense I hope fellow sailors can give me some advice! ! !
Installing a demister at the top of the process steam tower does not reduce the sodium ion content. Strict requirements must be met regarding the alkali metal content entering the reactor; otherwise, it can lead to catalyst deactivation or complete failure. It’s suggested to find solutions from other aspects!
I guess yours is an MTP device; catalysts are sensitive to alkali metals, so this approach makes sense. Since ionic sodium can only exist in liquids, there can be no sodium ions in gases. By using an efficient demister to prevent droplets from entering the subsequent reaction system as much as possible, the damage caused by sodium ions to the catalyst can be reduced.
