  • Patent number: 12533627
    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.

  • Publication number: 20250286385
    Abstract: A sea-land collaboration-based multi-energy coupling low-carbon new energy system includes a low-carbon power generation unit, a green fuel synthesis unit and an energy storage device which are arranged on a sea and an island, a green fuel comprehensive utilization unit and a carbon capture device which are arranged on the island and/or on land, and a multi-energy flow coupling-based sea-land collaborative low-carbon intelligent control center. The system generates power using abundant and stable solar energy and wind energy on the sea and the island, prepares hydrogen and ammonia using seawater, and the green fuel synthesis unit prepares green fuels using the prepared hydrogen and carbon dioxide produced by the system, such that the use of coal and natural gas in the green fuel comprehensive utilization unit is reduced; meanwhile, produced carbon dioxide is used as raw materials to prepare green fuels again.

  • Publication number: 20250200676
    Abstract: In an intelligent pollution and carbon reduction method based on combustion control and load distribution, a data processing layer, a multi-unit load distribution and operation optimization layer and a single-unit boiler multi-objective combustion optimization layer are used. The data processing layer, the multi-unit load distribution and operation optimization layer and the single-unit boiler multi-objective combustion optimization layer are embedded in a power plant information system in the form of modules. A load distribution and operation optimization method for a multi-source fuel blending combustion unit with economy as an objective is provided to overcome the operation optimization difficulty of the key production process of a multi-source fuel blending combustion cogeneration unit, such as sludge drying-steam distribution.

  • Patent number: 11980844
    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.
