Term explanation: Recirculating reflux: Liquid is drawn off from a side stream or the bottom of the tower; after being cooled through heat exchange, it is sent back to one or several plates above the extraction plate as reflux. This type of reflux is known as recirculating reflux.
The liquid is drawn off via a side stream or from the bottom of the tower; after being cooled through heat exchange, it is sent back to one or several trays above the extraction tray as reflux. This type of reflux is known as circulating reflux.
Circulating reflux is the top circulation oil, which is drawn from tray 26, cooled through heat exchange, and then returned to the top of the distillation column
Circulating reflux is a type of external reflux. A portion of the liquid phase fraction is drawn from a certain tray in the tower, cooled, and then returned to the tower as reflux. The return tray is usually one to several trays higher than the extraction tray; these trays are generally used only for heat transfer, without any role in mass exchange. Depending on the location, it can be divided into three types: top circulation, middle section circulation, and bottom circulation.

Circulating return fluid is the hot liquid drawn from the tower, cooled, and then pumped back into the tower.
Extracting the liquid from a side stream or the bottom of the tower, cooling it through heat exchange, and then returning it to one or several trays above the extraction tray as reflux is known as cyclic reflux.
