Title: Improvements in or relating to fractionating towers
IPC: B01D3/18
Filed: 1947-08-05
Abstract: 638,092. Treating liquids with gases. STANDARD OIL DEVELOPMENT CO. Aug. 5, 1947, No. 21317. Convention date, Feb. 25, 1943. [Class 55 (ii)] In a plate, adapted for use in a fractionating tower, wherein the liquid enters on one side of the plate and leaves at the opposite side, fewer fractionating elements, e.g. bubble - caps, are mounted on the outlet half of the plate than on the inlet half. This ensures that substantially the same quantity of vapour will pass through each half of the plate thereby reducing cross-flow of vapour from one side of the tower to the other, and also reducing entrainment. The number of fractionating elements on the outlet half of the plate should preferably be between 65 and 75 per cent of the number on the inlet half. In order to ensure a uniform distribution of liquid across the plate, the elements are arranged in curved rows conforming to the contour of the plate. Fig. 1 shows a plate 5 having fewer vapour chimneys 6 on the side near the liquid outlet weir 4 than on the side near the inlet weir 3. The majority of the chimneys are positioned in arcuate rows, e.g. A-A, but the row passing through the middle of the plate is straight. Fig. 2 shows how the plates 5 are arranged in a fractionating tower. Plates B and D are identical in construction and position, while plate C, although identical in construction with plate B and D, is positioned at 180 degrees rotation in the horizontal plane from the position of plates B and D. In the example, a plate having 55 bubble-caps on the inlet half and 38 on the outlet half is compared with a plate having 93 bubble-caps uniformly distributed, the comparison being made using water as the liquid and air as the vapour. The results show less splashing and less liquid gradient between inlet and outlet, in the case of the first-mentioned plate. The distillation of petroleum, the fractionation of cracked stocks, the stabilization of naphtha, and the production of various solvents, are referred to.
