I don’t understand anything about the distributor

I saw a thread on the forum regarding liquid distributors, which stated that nozzles should be the first choice in situations where contamination is likely to occur, with tray distributors being the second option. Isn’t it true that nozzles tend to get clogged easily? Then why is it said that nozzles are the first choice for situations where things tend to get dirty? Isn’t this a contradiction? Could that expert please explain it? Thanks~ Also, in the washing section of the refining unit, can nozzles be used as liquid distributors?

According to “Engineering Design and Application of Tower Equipment”, page P335, nozzle-type liquid distributors are pressure-type liquid distributors; the flow velocity of the liquid inside the tubes is high, which makes it less likely for the tubes or nozzles to get clogged, giving them relatively strong resistance to blockages.
I guess it’s because of the higher flow rate at the nozzle, which gives it relatively stronger resistance to clogging
Well, it does make sense~ That’s probably the reason
The fluid velocity at the nozzle is high, making clogging unlikely.
That’s probably the reasoning behind it; that’s how I understand it
The outlet of the nozzle is connected to the pump; one of them is under pressure, and a filter is installed to prevent blockages before the fluid enters the tower, while the other requires only that the maximum clear diameter of the nozzle’s passage be smaller than the nominal diameter of the spray orifice. In actual installations, it has been used in a certain ethylene distillation tower; from what I recall, its diameter was 12.6 meters. Oil coiling section and quench oil section. It seems they haven’t mentioned the traffic congestion situation on site yet. However, relatively speaking, the nozzles are a bit more expensive.
The nozzle has high pressure and fast flow rate, so it is not prone to clogging.
Thank you. I plan to give the nozzle a try
If your impurities are solid particles, as long as their particle size is larger than the nozzle aperture, they will cause blockage regardless of the flow velocity.
