Abstract: Many embodiments are directed to reactors and methods for reducing ship exhaust polluting emissions. Many such embodiments are directed to reactors implementing accelerated weathering of limestone (AWL) for carbon dioxide sequestration. Certain embodiments may also be used to mitigate high acidity of SOx scrubber effluents, while some embodiments solve both issues (i.e., seawater acidification and carbon dioxide pollution). Many embodiments are implemented on cargo ships (e.g., container ships and/or bulk carriers) and use seawater. Certain embodiments can utilize effluent from one or more SOx scrubbers as the source of seawater to decarbonize and/or neutralize water prior to being safely and permanently stored in the ocean.

Abstract: The invention relates to a process for separating carbon dioxide from a raw hydrogen product stream to produce a hydrogen product stream and a carbon dioxide product stream. The process includes the absorption of carbon dioxide in an absorption stage in an absorption medium and subsequent desorption of the carbon dioxide from the laden absorption medium in a plurality of decompression stages. According to the invention carbon dioxide substreams withdrawn from the decompression stages are combined into a carbon dioxide total stream and compressed in a plurality of serially arranged compression stages. Each compression stage having a suction pressure value is assigned at least one decompression stage with a corresponding desorption pressure value and the number of decompression stages corresponds at least to the number of compression stages.

Abstract: The invention relates to a process for removal of unwanted, in particular acidic gas constituents, for example carbon dioxide and hydrogen sulfide, from a crude synthesis gas by gas scrubbing with a scrubbing medium. According to the invention the flash gases obtained during the decompression of the laden scrubbing medium are supplied to a recompressor in order to recycle these to the crude synthesis gas and thus utilize them materially after the recompression. Alternatively or in addition the flash gases may also be supplied to a decompression turbine to recover refrigeration and mechanical work. If the recompressor and/or the decompression turbine are/is designed to have multiple stages, the flash gases obtained at different pressure levels are preferably supplied to a corresponding pressure level of the recompressor and/or of the decompression turbine.
