Activated carbon material cleaning

In this paper, the basic principles of four oil and gas recovery technologies such as adsorption method, condensation method, absorption method and membrane separation method are described, and the oil and gas recovery technology based on adsorption method is systematically analyzed.A kind of activated carbon material suitable for oil and gas recovery system by adsorption method was selected according to the design requirements.

The main equipment of oil and gas recovery system by activated carbon adsorption method, the activated carbon tank, is designed and calculated, and its strength is checked.The flowchart of the oil and gas recovery system by activated carbon adsorption in the laboratory of Environmental Engineering Department is also drawn, and the system is simulated in three dimensional.Finally, the economic and technical analysis of activated carbon oil and gas recovery technology is carried out, and it is considered that the application of activated carbon adsorption oil and gas recovery system will bring obvious social benefits, environmental benefits and economic benefits, and has a wide application prospect.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.china active carbon

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 determineswww.coconutactivatedcarbon.com 

Air velocity of empty tower :U= 1.0m /s.Original conditions:Treatment air volume :Q=20000 m'h, design temperature is 35° C, pressure is 1.01325×103Pa  Since the proportion of air in exhaust gas is far greater than that of pollutants, the properties of exhaust gas can be approximately viewed as the thermophysical properties of dry air. Please refer to Appendix 9 of Principles of Chemistry to obtain the following data:Properties of air mixture:Fluid density P;=1.147kg/ m', viscosity u,= 1.94×10-5 Pa.S, specific heat capacity C,=1.005kJ/(kg."C)
