What is the name of the equipment in the MTO process – riser arm?

(These terms are too technical; it’s likely that no one in foreign-speaking areas knows them, so I’m asking experts here for help.) (Confidentiality reasons; the original image has been removed.

Literally, it might refer to the lift arm and exhaust ports; since I haven’t seen the full diagram, I assume it is the channel through which the regenerated catalyst inside the regenerator returns to the reactor.
One more question: Are there exhaust holes on the lift arm? What is the exhaust hole for? ?
I don’t have specific information, so I’m not sure; I guess it’s the inlet and outlet of the gas used to boost the catalyst.
In the FCC, it is called a “cyclone arm”; if there is no cyclone effect, it is then referred to as the “lift pipe outlet flow arm”. The one below, I don’t know what its name is
Shouldn’t there be many points for introducing loose gas at the riser?
Riser arm refers to the catalyst pre-separator; “cut out in arm” means that the catalyst is separated in the pre-separator! ! ! Is it UOP’s MTO?
Bro, you’re being so mysterious! No pictures again. There isn’t much in the MTO reactor at all. The UOP reactor is equipped with a catalyst pre-separator and a cyclone separator. The DMTO reactor contains only a cyclone separator; they all have heat removal devices, either internal or external.
