摘要： Embodiments described herein relate to a method of geological CO2 storage via in-situ mineralization of trona, the method comprising injecting a mixture comprising CO2 and H2O in a geological formation comprising trona, wherein the H2O dissolves a portion of trona to form sodium carbonate in solution, and the CO2 reacts with the sodium carbonate to form sodium bicarbonate. Embodiments described herein further relate to a method of reactive absorption of CO2 and its simultaneous mineralization in trona comprising, mining of trona rock via solution mining to form a trona solution, reacting an input gas mixture comprising CO2 with the trona solution to form sodium bicarbonate. Embodiments described herein further relate to capture of carbon dioxide directly from air and storing it into solution mined trona as sodium bicarbonate.

摘要： A system and apparatus for treating and disposing of produced water in conjunction with flared gas, thereby avoiding problems associated with injecting produced water back into subsurface strata. The system is installed at or near the wellhead where produced water being treated is at a higher temperatures. Produced water is treated with ozone injection in a scrubber with heat applied through a flare gas field burner, which uses field gas from oilfield operations. A wet scrubber unit with scrubber packing is used to clean emissions. An amine solution is injected through spray nozzles in the scrubber unit for use as the wet scrubbing agent to absorb carbon dioxide. Amine solution with carbon dioxide is removed to an amine tank, and heated tor remove the carbon dioxide is gaseous form.

摘要： A method for recovering C2 components in a methane-containing industrial gas includes the steps of (1) cooling a compressed methane-containing industrial gas and performing gas-liquid separation; (2) absorbing C2 components in the gas phase by using an absorbent to obtain an absorption rich liquid; (3) returning the absorption rich liquid to the compression in step (1) or mixing the absorption rich liquid with the liquid phase obtained in step (1) to obtain a mixed liquid, and depressurizing the mixed liquid or the absorption rich liquid; (4) performing methane desorption on the depressurized stream to obtain a rich absorbent, or performing second gas-liquid separation on the depressurized stream, followed by methane desorption on the second liquid phase to obtain a rich absorbent; and (5) desorbing and separating the rich absorbent to obtain a lean absorbent and an enriched gas, and recycling and reusing the lean absorbent.

摘要： A system and a method for converting captured carbon dioxide (CO2) into hydrogen (H2) by using metallic iron or metallic magnesium in anaerobic process are described. In a first step, the CO2 can be absorbed in an alkaline solution such as NaOH and a soluble bicarbonate is formed. In a second step, the soluble bicarbonate HCO3— is converted into H2 by reacting it with zero valent metal, like metallic Fe (powder) or scrap Fe or Magnesium ribbon in anaerobic ambient conditions. Metal carbonate, like siderite, is created on the outer surface of Fe(0) and can be separated by the alkaline solution, which is recycled in the first reaction to be used for CO2 absorption. Exposing the separated siderite to weak acid, either citric acid or oxalic acid, zero valent metal is obtained, which is recycled in the second reaction. Alternatively, the siderite can be used as a raw material in the steel industry or cement industry or commercialized as an iron scrap. The generated H2 can be directly used for energy purposes or can be directed to another reactor comprising also bicarbonate solution and mix hydrogenotrophic methanogens to be converted into methane (CH4) or to a bioreactor comprising homoacetogenic bacteria to be converted into carboxylic acids, like acetic acid (CH3COOH). Alternatively, the reaction with Fe(0) or Mg(0), bicarbonate solution, CO2 and hydrogenotrophic methanogens for the production of CH4 can take place in one and same bioreactor.

摘要： The invention relates to a carbon-sequestering desalination brine waste processing system comprising a carbon sequestration system and a plurality of brine removal system for a desalinization plant. The carbon sequestration system is configured to receive brine from a brine source and inject at least one of CO2 or CO into the brine to provide carbon sequestrated brine. The plurality of brine removal systems are connected in series or parallel and sequentially extract brine and water vapor from the carbon sequestrated brine. Each brine removal system includes at least one atomizing unit for spray atomization and vacuum flashing the carbon sequestrated brine into atomized water vapor and concentrated brine. Further, each subsequent brine removal system includes at least one mineral extraction unit allowing sequential removal of minerals from the concentrated brine received from a previous brine removal system, and provide minerals and stable carbon products, till substantially zero brine discharge is achieved.

摘要： Disclosed are methods for seawater softening for the desalination plants (thermal and membrane) by using the carbon mineralization (CM) technique. Disclosed are several process flow diagrams in which the carbon mineralization is integrated at the upstream and/or downstream of the thermal and membrane desalination processes. By using these methods, the released CO2 from industrial factories, seawater feed minerals solutes shall be removed to improve the performance of the desalination plants. Most importantly, valuable products such as Ca/Mg carbonates and BaSO4, which are being used in building rocks, concrete, cement, paints, plastic, etc., can be produced.

摘要： Systems and methods of producing a concentrated solution from a gas stream are disclosed. The method of producing a concentrate solution includes introducing the gas stream having the contaminant into an absorption chamber, introducing a dilute liquid having the contaminant into the absorption chamber, at least one of the gas stream and the dilute liquid being at an elevated temperature, and contacting the gas stream with the dilute solution to produce a liquid-enriched gas stream and a concentrate solution. The systems for producing a concentrated solution include a source of a gas stream having a contaminant, a source of a dilute solution having the contaminant, and an absorption chamber fluidly connected to the source of the gas stream and the source of the dilute solution. The source of the dilute solution can have a subsystem for removing contaminants from the gas stream, constructed and arranged to receive the gas stream or a liquid-enriched gas and produce the dilute solution.

摘要： An efficient low-energy carbon dioxide removal system comprises an automated air mover equipped with sensing devices to measure flow rate, volume, level, pressure, temperature and concentration. Packing materials and air-liquid distributors are used in a multi-stage catalytic reactor. The multi-stage catalytic reactor processes ambient air and generates pure carbon dioxide gas and generates exhausted gas released to ambient air. In operation, air contacts the base solution in the presence of a catalyst via the air mover, distributor, and packing materials. The air reacts with the base solution thereby generating a base solution having carbon dioxide and generating exhaust (absorption reaction). Next, the exhaust is released from the reactor. Next, a catalyst is added, heat is applied to the base solution having carbon dioxide thereby generating carbon dioxide and generating a base solution without carbon dioxide (desorption reaction).
