Does the diesel stripping tower have trays?

Should a catalytic diesel stripping tower have trays? What are the advantages of having trays?
It features trays to ensure excellent separation performance, as well as a diesel flash point.
Larger distillation units have trays, as well as those without trays, but they do have packing, which is also used to improve the separation efficiency.
Upon on-site inspection during maintenance, or if one is involved in the design process, it is generally known that diesel stripping towers typically have six trays, which are used to increase the contact between the vapor and liquid phases. This allows light components to be removed through the reduction of the vapor pressure of the oil mixture, thereby ensuring that the flash point of the diesel meets the required standards.
Of course there is. The catalytic fractionator is a distillation column without a stripping section, while the diesel stripping column functions as the stripping section of such a fractionator
During the maintenance, I saw: there are six layers of trays, with floating valves； It is equivalent to the stripping section of the side-product stream in a fractional distillation tower.
The flash tower has no trays; it is equipped with a foam breaker at the top, while the stripping tower has trays
A tray must be present; a stripping tower can be considered as a section of a atmospheric pressure tower
For those with trays, the diesel hydrogenation process in our facility has 36 layers; this number is determined based on each respective feed volume.
To introduce steam using gas, trays are necessary in order to achieve an effective separation of light and heavy components!
