Removal Of Toluene From Rom Waste Gas By Honeycomb Adsorption Rotor With Modifid13X Molecular Sieves

The adsorption rotor as a new and efficient adsorption device has the advantages of stable operation, small resistance, compact structure, small overall equipment footprint compare with the fixed-bed unit. The paper used a fixed-bed adsorption unit to compare the adsorption properties of13X zeolite and modified13X zeolite (M-13X). On that basis, we choosed M-13X which has better adsorption property to manufacture a honeycomb adsorption rotor, and used gaseous toluene as simulated pollutant to research the effect of the rotor operating parameters and the feed gas parameters on the adsorption efficiencyThe experimental results indicate the honeycomb adsorption rotor has a good humidity resistance. The removal efficiency of honeycomb adsorption rotor achieve maximum value with optimal rotor speed and optimal generation air temperature. Moreover, an appropriate flow rate ratio should take into account the removal efficiency and energy consumption. When the recommended operating parameters are regeneration air temperature of180℃, rotor speed of2.8-5r-h-1, flow rate ratio of8-12, the removal efficiency keep over90%for the toluene gas which concentration is100mg·m-3and inlet velocity is2m-s-1. The research provided design experience and operating parameters for industrial application of honeycomb adsorption rotor. It show that lower empty bed velocity, faster rotor speed, higher temperature are necessary to purify higher concentration organic waste gases.
