If the gas speed is very small, the size of the adsorber is large and uneconomical.
If the gas velocity is too large, the pressure drop will increase and the adsorption efficiency will be affected.The optimum gas velocity was determined by experiment.
https://www.dxdcarbon.com/The adsorption design can not pursue too high adsorption efficiency, the empty tower speed value is reduced, it will make the adsorption bed volume, the amount of adsorbent and equipment cost increased greatly;On the contrary, it is not appropriate to take too large empty tower gas speed. Although the equipment cost is low, the adsorption efficiency drops a lot, and the pressure drop of the system will rise rapidly with the increase of the empty tower speed, resulting in excessive power consumption. Therefore, due to the selection of the appropriate air speed of the empty tower, the most suitable air speed of the empty tower is 0.8~1.2m/s"21, according to the empirical conclusion, this design determinesAccording to the above research results, a coke filter was designed. The application of the equipment solved the problems that the feedstock gas compressor in the urea blackening unit could not run for a long period due to the vibration caused by the scaling of the rotor, the blockage of the flow channel and the problems that the naphthalene formation in the heat exchanger affected the heat transfer effect.
activated carbon manufacturerThe preliminary design of the adsorption device was carried out. From the comparison of operating cost and product output value, the economic benefit was remarkable, and the pollution of benzene to the environment was eliminated.
