Firstly, according to the characteristics of flue gas from Chinese refineries, three feasible CO2 separation technologies are selected. These are pressure swing adsorption （PSA）, chemical absorption （CA）, and membrane absorption （MA）. Secondly, an economic assessment of these three techniques is carried out in accordance with cash flow analysis. The results show that these three techniques all have economic feasibility and the PSA technique is the best. Finally, to further optimize the three techniques, a two-level fuzzy comprehensive evaluation model is established, including economic, technological, and environmental factors. Considering all the factors, PSA is optimal for Chinese refineries, followed by CA and MA. Therefore, to reduce Chinese refineries carbon emission, it is suggested that CO2 should be captured from off-gases using PSA.展开更多

Takingthe advantage of his position, he collectednumerous proven prescriptions and folkrecipes as well as secret prescriptions of afamily handed down from generation togeneration, and prepared ready-made herbalcompounds. With unique recipes, carefully-chosen ingredients, fine technology andconspicuously curative effect of such ready-made herbal compounds, BeijingTongrentang thus established itself areputation. In 1952, under the leadership of LeSongsheng, descendant of the Le family andformer manager of Tongrentang, thecountry’ s first medicinal herb tablet producer,Beijing Tongrentang Chinese Medicinal HerbRefinery, was set up.
