nature : also known as Linde (Linde) sieve column. A sieve column. Its structure shown in the figure, as compared with ordinary sieve column highlighted the improvements are : â‘?tray of liquid entrance located bubbling for the structure, so that a liquid into the tray and can rapidly bubbling to promote better gas-liquid contact area increased tray effective utilization; â‘?already in the tray Sieve basis, a certain number of additional guidance hole, the hole opening direction and flow Trays in the same direction, the direction Kong Trays downwash flow of play certain role in promoting, Trays of liquid layers more uniform and to achieve better gas-liquid contact effect. It also made tray of liquid layer thinner and more uniform, more small pressure drop, further enhancing the mass transfer tray efficiency. Applied ethylbenzene - styrene vacuum distillation tower, tray efficiency is improved by 13%, down tray pressure drop of 15%. This tray alternative valve tray results have been very significant, but also to the propane-propylene separation, light hydrocarbon separation of distillation and production of ammonia scrubber tower.
