摘要： 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.

摘要： A filter is provided for removing contaminants from a gas flow (e.g., an air flow). Multiple panel filters are arranged in a filter housing. The panel filters are arranged parallel or near-parallel to a main gas flow direction and spaced apart to define elongated gas flow channels between adjacent panel filters, each elongated gas flow channel extending generally in the gas flow direction. The elongated gas flow channels include inlet channel(s) and outlet channel(a) arranged in an alternating manner, the inlet channel(s) configured receiving the gas flow at the inlet end and the outlet channel(s) outputting a filtered gas flow from the outlet end. Gas flow redirecting structures are arranged to redirect the gas flow in each inlet channel through adjacent panel filter(s) and into adjacent outlet channel(s). The filter may provide a pressure drop of less than 3 iwg, less than 1 iwg, or less than 0.3 iwg.

摘要： The disclosure provides seven integrated methods for the chemical sequestration of carbon dioxide (CO2), nitric oxide (NO), nitrogen dioxide (NO2) (collectively NO2, where x=1, 2) and sulfur dioxide (SO2) using closed loop technology. The methods recycle process reagents and mass balance consumable reagents that can be made using electrochemical separation of sodium chloride (NaCl) or potassium chloride (KCl). The technology applies to marine and terrestrial exhaust gas sources for CO2, NOx and SO2. The integrated technology combines compatible and green processes that capture and/or convert CO2, NOx and SO2 into compounds that enhance the environment, many with commercial value.

摘要： One aspect of the invention relates to a method comprising a single-stage conversion of an atmospheric pollutant, such as NO, NO2 and/or SOx in a first stream to one or more mineral acids and/or salts thereof by reacting with nonionic gas phase chlorine dioxide (ClO20), wherein the reaction is carried out in the gas phase. Another aspect of the invention relates to a method comprising first adjusting the atmospheric pollutant concentrations in a first stream to a molar ratio of about 1:1, and then reacting with an aqueous metal hydroxide solution (MOH). Another aspect of the invention relates to an apparatus that can be used to carry out the methods disclosed herein. The methods disclosed herein are unexpectedly efficient and cost effective, and can be applied to a stream comprising high concentration and large volume of atmospheric pollutants.

摘要： An energy-saving system using electric heat pump to recover flue gas waste heat for district heating uses flue gas waste heat recovery tower to absorb the sensible and latent heat in the high-temperature flue gas by direct contact heat and mass transfer. The circulating water is sprayed from the top and the flue gas flows upwards in the tower. The electric heat pump is indirectly connected with circulating water through the anti-corrosion and high-efficiency water-water plate heat exchanger. The return water of the heat-supply network enters the electric heat pump through the anti-corrosion and high-efficiency water-water plate heat exchanger and exchanges heat indirectly with the high-temperature circulating water. The electric heat pump uses the electric energy of the power plant as the driving power.
