The methanol was adsorpted by water via the layered packing cross-flow rotating bed. The effects of operating parameters such as high gravitational factor (?), empty bed gas velocity (u), liquid spray density (q) and inlet methanol concentration on the overall volumetric gas-phase transfer coefficient (KGa) of methanol were explored. The results indicated that KGa increased with the increases of ?, u and q, but the inlet methanol concentrations had a negligible effect on the KGa of methanol. Under the conditions of ?=100, u=0.9 m/s, q=17.6 m3/(m2?h), the inlet concentration of methanol was 14000 mg/m3, the absorptivity of methanol on rate was 97%, the KGa values of methanol reached 27 s?1, which was 1.1~3.9 times of the countercurrent-flow rotating packed bed with blade packing, 2~7.7 times of the cross-flow rotating packed bed with blade packing. It showed that the device can effectively reduce the mass transfer resistance of gas film control. When the inlet concentration of methanol gas was stable, high u and low q, ???value had great influence on the KGa of methanol. The mass transfer efficiency in the process of methanol absorption was effectively enhanced. The empty bed gas velocity of this equipment reached 1 m/s, which was 3~12 times of the countercurrent-flow rotating packed bed with blade packing.
