  • Patent number: 10239017
    Abstract: A method for removing carbon dioxide directly from ambient air, using a sorbent under ambient conditions, to obtain relatively pure CO2. The CO2 is removed from the sorbent using process heat, preferably in the form of steam, at a temperature in the range of not greater than about 130° C., to capture the relatively pure CO2 and to regenerate the sorbent for repeated use. Increased efficiency can be achieved by admixing with the ambient air, prior to contacting the sorbent, a minor amount of a preferably pretreated effluent gas containing a higher concentration of carbon dioxide. The captured carbon dioxide can be stored for further use, or sequestered permanently. The above method provides purified carbon dioxide for further use in agriculture and chemical processes, or for permanent sequestration.

  • Patent number: 9616378
    Abstract: A system and method of reducing the net carbon dioxide footprint of an industrial process that generates power from the combustion of hydrocarbon fuels in which ambient air is admixed with up to 50% by volume of an effluent gas from the power generator of the industrial process, in order to substantially increase the CO2 concentration in the air prior to treatment. The treatment comprises adsorbing CO2 from the admixed ambient air utilizing a cooled, porous substrate-supported amine adsorbent, wherein the porous substrate initially contacts the mixed ambient air containing condensed water in its pores, which act as an intrinsic coolant with respect to the exothermic heat generated by the adsorption process.

  • Patent number: 9546409
    Abstract: A process for producing DRI from iron ores, utilizing a gas produced from fossil fuels, containing sulfur compounds and BTX, heating said gas in a heater, preferably a regenerator, wherein heat is transferred from a previously-heated solid material to the gas. Flowing the hot gas through a bed of DRI particles, iron oxides or other equivalent material, outside of the reduction reactor, where said material adsorbs sulfur compounds and destroys BTX. The resulting gas, free from sulfur compounds and BTX, is combined with a reducing gas stream from the reduction reactor after H2O and CO2 is at least partially removed for regenerating its reducing potential, with or without undergoing previous cleaning, is used for producing DRI. One inventive embodiment comprises producing DRI at high temperature giving advantageously higher productivity and energy savings when using hot DRI in an electric arc furnace lowering the capital and operational costs of steelmaking.

  • Patent number: 9522359
    Abstract: A process and an apparatus are described, which remove acid gas from a gas stream in a manner that generates a product gas stream at a higher temperature while consuming less energy than the existing technology. The process requires maintaining a positive product gas temperature differential. The apparatus enables the positive gas temperature differential to be maintained by manipulating the absorber column operating conditions and/or the solvent chemistry to increase the amount of absorption and reaction in the absorber.

  • Patent number: 9433896
    Abstract: A method and a system for removing carbon dioxide directly from ambient air, using a sorbent under ambient conditions, to obtain relatively pure CO2. The CO2 is removed from the sorbent using process heat, preferably in the form of steam, at a temperature in the range of not greater than about 130° C., to capture the relatively pure CO2. Increased efficiency can be achieved by admixing with the ambient air, prior to contacting the sorbent, a minor amount of a preferably pretreated effluent gas containing a higher concentration of carbon dioxide. The captured carbon dioxide can be stored for further use, or sequestered permanently. The system provides the sorbent substrate and equipment for carrying out the above method, and for obtaining purified carbon dioxide for further use in agriculture and chemical processes, or for permanent sequestration.
