    • A method and corresponding apparatus for separation of carbon dioxide from an exhaust gas of a fossil-fired power are provided. In an absorption process, the exhaust gas containing carbon dioxide is brought into contact with an absorption medium so that the absorption medium is laden with carbon dioxide. In a desorption process, vapor from a water/steam circuit of the fossil-fired power plant is heated, wherein a laden absorption medium is regenerated. In a subsequent expansion process, the regenerated absorption medium is expanded so that a vapor and an expanded absorption medium are formed, wherein the vapor is recirculated into the desorption process. The laden absorption medium is divided into a first part stream and a second part stream. Only the second part stream is brought into heat-exchanging contact with the expanded absorption medium. The first and second part streams are supplied to the desorption process at different process stages.
    • 提供了一种用于从二氧化碳与化石燃烧废气排出的方法和相应的装置。 在吸收过程中,使含有二氧化碳的废气与吸收介质接触,使得吸收介质充满二氧化碳。 在解吸过程中,加热来自化石燃料发电厂的水/蒸汽回路的蒸气,其中再生有载荷的吸收介质。 在随后的膨胀过程中,再生的吸收介质被膨胀,从而形成蒸汽和膨胀的吸收介质,其中蒸汽再循环到解吸过程中。 负载吸收介质被分成第一部分流和第二部分流。 只有第二部分物流与扩张的吸收介质进行热交换接触。 第一和第二部分流在不同的工艺阶段被提供给解吸过程。
