The gas-liquid flow pattern on the trays of a catalytic cracking stabilizer is ( ) flow. A、Counterflow B、Parallel C、Folded D、Wrong. What is the correct answer? Is it counterflow or cross-flow?

This issue should be understood as follows: it is counterflow for a single tray, but countercurrent for the entire tower. http://img1.jingpinke.com/cover/resource/4028811d-1637f5dc-0116-37f5fde4-2e6a

The reverse flow side is larger! The intermediate feed also falls from top to bottom to the bottom of the tower, and then the reboiler absorbs heat to vaporize it upward. The liquid phase descends while the gas phase rises; if this isn’t counterflow, then what is?
