Abstract (en)
[origin: WO2019091736A1] The present invention relates to a gas-solid separation device that is specially adapted to the external risers of catalytic cracking units. The device comprises a tubing (19) forming substantially an angle of 90° with respect to a riser (2), said tubing (19) being divided into two tubes (4) forming between them an angle 2*γ, γ being between 5° and 85°. This device makes it possible simultaneously to channel the stripping gases and improves the overall effectiveness of separation due to better control of contact time. The present invention also relates to a catalytic cracking method using said gas-solid separation device.
