ABSTRACT:
The provision and operation of backmix coolers is facilitated by a cooler arrangement that has the backmix portion of the cooler in an inverted position. In this position the heat exchange portion of the cooler is located above the source of hot catalyst. Hot catalyst for heat exchange in the cooler enters and leaves the heat exchange zone from below the location of the heat exchange tubes. The inverted position prevents any collection of debris in the bottom of the cooler, eliminates high velocity impingement of fluidizing medium on the tube, and facilitates the incorporation of the cooler in FCC units by avoiding interference with other equipment.
