If the gas speed is very small, the size of the adsorber is large and uneconomical.https://www.dxdcarbon.com/ 

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. activated charcoal wholesale australia 

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 determines Its adsorption performance mainly depends on several main material parameters and process parameters on it [8. Material parameters including carbon adsorption porosity, thickness of honeycomb structure and the content of carbon; process parameters including fluid flow rate and concentration of the adsorption properties of adsorption, can adsorption depends on the carbon structure and adsorption properties of features such as molecular weight). The curve is one of the main performance characterization of adsorption, adsorption is the adsorbate concentration ratio before and after the change over time of a function [9 '. This ratio is 0.95, the amount of adsorption properties of adsorption is called penetration capacity. Penetration capacity depending on the fluid flow rate, the concentration of the adsorbate and honeycomb carbon component content

Factors such as [10. For honeycomb activated carbon, the wall thickness is a very important parameter, by changing the wall thickness to improve its adsorption efficiency. Under the same porosity, thickness increases, the honeycomb carbon content per unit volume also will increase, which can improve the adsorption capacity. This is because the wall thickness increases, the fluid channel in the cellular cross-sectional area reduced, so the real surface or volume flow rate will increase. At the same time, the contact between adsorbate and carbon efficiency will, there is a balance between the two. Under the given conditions, the balance will determine adsorption increase or decrease. If the adsorbate at higherthe diffusion rate diffuses to the inside of the honeycomb wall, and the empty adsorption site can be continuously adsorbed, so the thick-walled honeycomb should have better adsorption efficiency and adsorption capacity"Determination of air velocity and cross-sectional area of empty towerThe empty tower gas velocity is the velocity of gas passing through the entire cross section of the adsorber.The selection of air velocity not only directly determines the size and pressure drop of the adsorber, but also affects the adsorption efficiency.
