Vertical pipes placed in chemical equipment are called risers.

The role of the riser is different in different equipment, but it mainly transports the material at the upper and lower parts of the equipment. For example, most types of separation columns have two-phase countercurrent flow, and the riser can transport the material between the two trays. Another example is to ensure the circulation of solid particles in the fluidized bed reactor. The particles collected in the upper part of the reactor can pass through the bottom of the riser circulator to complete the circulating flow of the particles.
