The dense phase carbon dioxide is then further pressurized to a pressure matching a pressure, less hydrostatic head, existing deep within a porous geological formation, a deep aquifer, a deep ocean location or other terrestrial formation from which return of the CO2 into the atmosphere is inhibited. The combustion products are then expanded through a power generating device (48). The combustion products are then passed through a condenser (80), and then is routed back to the gas generator. Below are some links with additional information about the affects of the products. Water is also delivered into the gas generator to control the temperature of the combustion products. Collection efficiency is further improved by a cascading water film or algae-laden water film on the inside of the stack wall and on surfaces of an optional internally mounted vortex generator to eliminate the re-entrainment of small particles and for ease of transporting the captured particles in a slurry. The stack can also be utilized as a photochemical or a biological reactor to promote a photosynthesis reaction between carbon dioxide and algae-laden water to form carbohydrate substrates for carbon dioxide sequestration and utilization. Abstract --- Industrial combustion facilities are integrated with greenhouse gas-solidifying fertilizer production reactions so that CO2, CO, NOx, and SOx emissions can be converted prior to emission into carbonate-containing fertilizers, mainly NH4HCO3 and/or (NH2)2CO, plus a small fraction of NH4NO3 and (NH4)2SO4.
Abstract --- A process for selectively removing carbon dioxide from a gaseous stream by converting the carbon dioxide to a solid, stable form is provided. The method includes introducing the first oxygen stream and a solid fuel, such as coal, into a solid-fuel gasifier for converting the first oxygen stream and the solid fuel into a combustible gas and combusting the gas in the presence of the second oxygen stream, the combusting step including the step of introducing water into the combustor during the combusting step for generating an exhaust stream of carbon dioxide and steam. The method for converting CO2, CO, NOx, and SOx emissions into fertilizers includes the step of collecting these materials from the emissions of industrial combustion facilities such as fossil fuel-powered energy sources and transporting the emissions to a reactor. In the reactor, the CO2, CO, N2, SOx, and/or NOx are converted into carbonate-containing fertilizers using H2, CH4, or NH3. The carbonate-containing fertilizers are then applied to soil and green plants to (1) sequester inorganic carbon into soil and subsoil earth layers by enhanced carbonation of groundwater and the earth minerals, (2) reduce the environmental problem of NO3-runoff by substituting for ammonium nitrate fertilizer, and (3) stimulate photosynthetic fixation of CO2 from the atmosphere by the fertilization effect of the carbonate-containing fertilizers.
The invention enhances sequestration of CO2 into soil and the earth subsurface, reduces N03- contamination of surface and groundwater, and stimulates photosynthetic fixation of CO2 from the atmosphere. Soil alkalinity is vital to plant health. Because of this, pH isn’t as important as alkalinity when it comes to your health. As per the experts, there isn’t any way to de-contaminate the drinking water without even ionizing it. What can I expect from drinking ionized water? This solid mineral precipitate can be safely stored for extended periods of time, such as by burying the precipitate in the ground or depositing the precipitate into storage sites either on land or into a body of water. In the final step, a mineral ion is added to the reaction so that a precipitate of carbonate salt is formed. Sedimentation ensures that the marine environment is an overall carbon sink through carbonate sequestration. A harvesting system ensures maximum organism growth and rate of CO2 uptake. An on-site biological sequestration system directly decreases the concentration of carbon-containing compounds in the emissions of fossil generation units. Abstract --- A plant for producing Fischer-Tropsch liquids and electrical power with greatly reduced emissions of carbon dioxide to the atmosphere is made up of a syngas generator unit, an air separation unit, a Fischer-Tropsch unit, a CO2 removal unit, and a combined cycle electricity generation unit.
After removing a portion of the nitrogen, the remaining gas is primarily oxygen, which is routed to a gas generator (70). The gas generator has an igniter and inputs for the high pressure oxygen and a high pressure hydrogen-containing fuel, such as hydrogen, methane or a light alcohol. The remaining gas is primarily oxygen, which is then compressed and routed to a gas generator. A portion of the water is collected for further processing and use and the remainder is routed back to the gas generator. Some hydrogen is also removed by reaction with the iron oxide, reducing Fe2O3 to FeO, while the remainder of the hydrogen passes through the fluid beds, leaving in a purified state, i.e., PEM fuel cell quality. Virtually all of the CO is removed by a water gas shift reaction, forming hydrogen and CO2, with the remainder being removed by reaction with the iron oxide, reducing Fe2O3 to FeO. nước khoáng ion kiềm is recoverable by the use of a gas turbine fueled by predominantly hydrogen and a steam turbine powered by steam generated by cooling exhaust gases from the gas turbine. The CO2 extraction methods and systems involve the use of chemical processes, mineral sequestration, and solid and liquid sorbents.
