Abstract: The present invention relates to a method for carbon dioxide capture and concentration by partitioned multistage circulation based on mass transfer-reaction regulation. In the present invention, multiple means such as multistage circulating absorption, intelligent multi-factor regulation, pre-washing and cooling, inter-stage cooling, post-stage washing, slurry cleaning, cooling water waste heat utilization, small-particle-size and high-density spraying, external strengthening field such as a thermal field/ultrasonic field/electric field, and catalysis by composite catalyst are adopted, so that the target for low cost, low energy consumption, stability and high efficiency is realized. The secondary pollutants are effectively inhibited while carbon dioxide is efficiently captured; meanwhile, high-efficiency capture, low-energy desorption, and high-purity concentration of carbon dioxide are implemented.

Abstract: A first electronic device displays a first interface including first content, where the first interface further includes a status bar and/or a navigation bar of the first electronic device. A second electronic device displays a first projection window including the first content, where the first projection window further includes any one of the status bar, the navigation bar, and a title bar of a projection application. The first electronic device switches from displaying the first interface to displaying a second interface, where the second interface includes second content, and the second interface does not include the status bar and the navigation bar. The second electronic device switches from displaying the first projection window to displaying a second projection window, where the second projection window includes the second content, and the second projection window does not include the status bar, the navigation bar, and the title bar.

Abstract: The invention relates to a low-cost and high-efficiency absorption-desorption decoupling method for contaminant-CO2 synergistic capture. According to the method, an optimization model of absorption-desorption decoupling control for contaminant-CO2 synergistic capture under different working conditions is built, the optimization objective is to obtain high-purity liquid contaminants and CO2 at low cost and efficiently, and an adaptive penalty function is constructed to transform a solution of a constrained optimization problem into that of an unconstrained optimization problem, thereby controlling parameters in a real-time, precise and stable manner. Moreover, supported by means of flue gas pre-scrubbing and cooling, multi-stage intercooling and column-top demisting, the method of the present invention achieves efficient capture of contaminants and CO2.
