摘要： A quench mixing device (100, 200, 300) is disclosed for mixing multiphase process fluids in 5 the inter-bed region of a concurrent downflow reactor (10) for obtaining homogeneity of the temperature and chemical composition of the mixed stream. The quench mixing device comprises of outer mixing zone (109), inner mixing zone (120), swirl mixing zone (151) and exit zone. Due to the position of the disperser (142), the liquid coming from above is dispersed in droplets. The fluid impact on the other side of the outer mixing zone. The gas is bubbled into 0 liquid in the inner mixing zone. The fluids enter the swirl mixing zone via two-phase duct (131) which is shaped to have low pressure loss and high velocity at the outlet to induce dispersed regime. The outlet of the two-phase duct is placed such that liquid is injected into the swirl zone below liquid surface, causing increased momentum for inducing liquid swirl in the swirl zone and increased number of rotations.
