A human load of regularly measuring a pH of a position 4 meters from a discharge point during a term of a commissioning of a ship with a scrubber apparatus is reduced. Provided is an apparatus provided inside a ship having a scrubber, including a first pH measuring instrument which measures a pH value of washing water discharged from the scrubber to outboard, a second pH measuring instrument which measures a pH value of washing water supplied from outboard to the scrubber, and a calculating unit which calculates a pH value of water at a predetermined position outboard, based on a dilution ratio which shows a ratio by which the washing water discharged to outboard is diluted at the predetermined position outboard, the pH value measured by the first pH measuring instrument, and the pH value measured by the second pH measuring instrument.

A ship flue gas scrubbing apparatus and scrubbing method are provided. The apparatus includes a housing, an upper scrubbing layer at the upper side inside the housing, and a liquid collecting pool in the lower side inside the housing, a flue gas leading-in port between the scrubbing layer and the liquid collecting pool, a scrubbing seawater inlet above the scrubbing layer, and a cooler located at a flue gas passage between the flue gas inlet outside the housing and the scrubbing layer. The method includes leading flue gas, cooling, injecting scrubbing seawater, scrubbing and other steps.

Systems and methods to separate carbon dioxide from flue gases and sequester carbon dioxide are described here. By using the properties of carbon dioxide and the temperature in a body of water (e.g., the ocean or freshwater body of water) or the temperatures of the ambient atmosphere, gaseous carbon dioxide can be converted to a liquid and separated from other gases. Pressure used to separate carbon dioxide from other gases may also be used to sequester liquid carbon dioxide. The liquid carbon dioxide is inert and can be discharged into the ocean without dissolving in seawater and acidifying the ocean. The liquid carbon dioxide may further be densified to be denser than seawater. The liquid carbon dioxide can then sink to the bottom of the ocean or be injected into ocean sediments or sediments and rocks beneath the ocean floor, inert and sequestered for the long term.

According to an embodiment of the present disclosure, an exhaust gas treatment apparatus may include: a preprocessor configured to primarily remove harmful substances from exhaust gas produced by combustion; and a postprocessor configured to further remove harmful substances from preprocessed gas, which is the exhaust gas from which the harmful substances have been primarily removed by the preprocessor, wherein the postprocessor may include a postprocessor housing having a preprocessed gas inlet through which the preprocessed gas is introduced and a postprocessed gas outlet through which postprocessed gas from which harmful substances have been further removed by the postprocessor is discharged and forming a flow path of the preprocessed gas therein, and a diffuser disposed adjacent to the preprocessed gas inlet and configured to diffuse the preprocessed gas introduced through the preprocessed gas inlet.

The present invention relates to a process and an apparatus for utilizing fossil energy with low carbon emissions, which belongs to a technical field of clean energy and climate mitigation. The present invention is applicable for utilizing fossil, biomass and other carbon-containing fuels in coastal and marine areas to produce clean energy with low carbon emissions to atmosphere and low cost. The process comprises the main steps of carrying out the oxygen enriched combustion and using seawater to scrub the flue gas once to realize carbon capture, and the scrubbing water is recovered to a water quality in accordance with legal requirements and then is discharged into the ocean to realize carbon storage of ocean natural alkalinity, so that the resources of carbon sink and carbon pool in natural ocean are used to reduce greenhouse gases in the atmosphere in a safe and environment-friendly form.

Provided is a desulfurization device that allows for the easy and accurate disposition of a spray pipe inside an absorption tower. Provided is a desulfurization device including: an absorption tower (10); and a spray pipe (20) disposed inside the absorption tower (10). The spray pipe (20) includes: a cylindrical pipe portion (21), the leading end of which is closed; and an attachment flange (24) attached to the pipe portion (21). The absorption tower (10) includes: an opening hole (14e) opening toward the side; and a flange (14a) disposed around the opening hole (14e). The attachment flange (24) and the flange (14a) are detachably attached.

A device and method for removing pollutants from the air including a reaction unit containing a reaction fluid dispersion medium such as film fill, a reaction fluid distribution system for distributing an aqueous reaction solution over the reaction fluid dispersion medium, and an air mover, located above the reaction fluid distribution system and reaction fluid dispersion medium, for drawing or forcing air into the reaction unit to contact the sodium or potassium hydroxide. The pollutant in the air reacts with the aqueous reaction solution to form an aqueous reaction product thus removing the pollutant from the air. The device may include humidifiers to humidify the ambient air before it contacts the reaction fluid.

A method for ship ballasting includes receiving, at a carbon negative energy storage system, input comprising calcium oxide and water and reacting, within a reaction chamber of the carbon negative energy storage system, the calcium oxide and water to release energy and generate calcium hydroxide. The method includes directing, by the carbon negative energy storage system, the released energy to a requesting end user and providing, by the carbon negative energy storage system, the calcium hydroxide to a marine vessel ballasting system. The method includes releasing a mixture of the calcium hydroxide and ballast water from the marine vessel ballasting system into the ocean to sequester atmospheric CO.sub.2.

A method and installation for removing a gas from a flow of a gas mixture. A first liquid (82) is introduced in the flow (106) for evoporative cooling and saturation of the gas mixture. Small droplets of a second liquid (84) are provided which are capable of adsorbing and dissolving said gas and of a size small enough not to be sedimented by gravitation and big enough to be centrifugally separated. The small droplets are sprayed into the flow for adsorbing and dissolving said gas into the droplets, and the small droplets are centrifugally separated from the flow.

The disclosure provides a method of treating flue gas that has one or more components. The method comprises passing a solution through both a magnetic field and an electric field to form an activated solution. The method also comprises contacting the activated solution with the flue gas so that the one or more components of the flue gas are at least partially absorbed by the activated solution to form a residue solution.
