Packed tower absorption in the field of chemical industry, not only in general concentration and low concentration of industrial purification also plays an indelible role. A countless number of engineering practice shows that reasonable system technological process and filler in absorption tower design can fully guarantee of purification effect. This design is to packing of polypropylene ladder ring is applied to the water absorption of ammonia absorption tower design. Under the same conditions, using the countercurrent mode and flow can maximize the average driver, which can obtain a greater absorption efficiency. In addition, as a result of the sorbet in the process of using countercurrent flow and the flow of gas is opposite, so this way is conducive to further improve the solute absorption rate, and can maximize reduce the wastage of the mobile phone usage. Therefore, no matter from the Angle of efficiency or from an economic point of view adopted more suitable than the adoption and flow upstream. Through a series of data, literature, and operating conditions, we can calculate the flood point gas velocity, superficial gas 3 velocity, column diameter, crosssectional area of the tower, and further calculate the mass transfer unit height, mass transfer unit number, finally calculate the packing the height of the absorption tow
