The effects of steam injection on stripping efficiency were studied in an effort to improve operation of a fluidized bed stripper. Experiments extend earlier measurements in a geometrically and dynamically scaled half-column [I. Rose, H. Cui, T. Zhang, C. McKnight, J.R. Grace, X.T. Bi, C.J. Lim, Toward an ultimate fluidized stripper, Powder Technol. 158 (1–3) (2005) 124–132]. In the present work,...
Experiments were conducted in the geometrically- and dynamically-scaled UBC half-column to test different configurations that might significantly reduce stripper shed fouling and increase run length, while providing little or no decrease in stripping efficiency in two commercial fluid cokers. The results showed that a series of horizontal gas jets, without baffles, constrained to use no more steam...
