  • Publication number: 20200047116
    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.

  • Publication number: 20200047117
    Abstract: The invention relates to a process for removing hydrogen sulfide and carbon dioxide from a feed gas stream. H2S in the feed gas stream is converted to elemental sulfur in a Claus unit. At least a part of the gas stream obtained is contacted with an aqueous lean absorbing medium in an absorption zone at a pressure between 0.9 and 2 bara. The aqueous lean absorbing medium used comprises one or more amines chosen from: —a polyamine in the absence of tertiary amine functionalities having a pKa sufficient to neutralize carbamic acid, the polyamine having at least one primary amine functionality having a pKa smaller than 10.0 at 25° C., —a polyamine in the absence of tertiary amine functionalities having a pKa sufficient to neutralize carbamic acid, the polyamine having at least one secondary amine functionality having a pKa for each sorbing nitrogen smaller than 10.0 at 25° C. The process is improved as compared to a process involving Claus off-gas treatment with (activated) MDEA.

  • Publication number: 20200047120
    Abstract: The invention relates to a method for separating off and immobilizing carbon dioxide and/or carbon monoxide from an exhaust gas (18). In the method, a stoichiometric ratio of carbon dioxide to hydrogen, and/or of carbon monoxide to hydrogen, which is suitable for a methanation reaction is set by virtue of a corresponding quantity of hydrogen or alternatively carbon dioxide and/or possibly carbon monoxide being supplied, with an auxiliary gas (24), to the exhaust gas (18). Subsequently, a catalytic reaction is performed in which, as starting products, carbon dioxide and/or carbon monoxide and hydrogen are converted into methane and water. The methane is separated off from the product of the catalytic reaction and is subsequently split into carbon and hydrogen, wherein the carbon takes solid form. The split-off carbon is collected and disposed of.

  • Publication number: 20200047126
    Abstract: This specification describes membrane based filtration and softening systems and methods. A system has a microfiltration or ultrafiltration (MF/UF) membrane unit upstream of a nanofiltration or reverse osmosis (NF/RO) membrane unit, optionally with no intermediate tank. In some cases, the system and method may be used with feed water provided at municipal line pressure to the membranes. NF/RO permeate is collected in a tank and then pumped to a header. Treated water may be drawn from the header for use or recycled to the system, for example to backwash or flush one or both of the membrane units. In a combined process, NF/RO permeate flushes the feed side of the NF/RO unit and then backwashes the MF/UF unit. In another process, the MF/UF unit and NF/RO unit are filled with NF/RO permeate before being placed in a standby mode.

  • Publication number: 20200047154
    Abstract: The present invention covers a novel method for creating an adsorbent and the resulting novel adsorbent. The method may be used to remove pollutants/unwanted chemicals from water, air, other gases, biological fluids (such as blood, urine, lipids, protein fluids), and other fluids (such as fuel). The adsorbent may be used to remove heavy metals (for example, lead), organic pollutants, inorganic non-meal pollutants (for example, nitrates and bromates). Accordingly, the current invention has many applications including but not limited to water treatment, wastewater treatment, biomedical fluid treatments, gas cleanup, and fuel (oil, gas) cleanup.

  • Publication number: 20200047156
    Abstract: According to an example aspect of the present invention, there is provided a method of removing dissolved contaminants from an aqueous liquid. The aqueous liquid is contacted with an adsorbent which comprises a finely divided lignocellulosic material, which has been subjected to extraction to remove hemicellulose and/or other components therefrom, to bind at least a portion of the organic compounds to the adsorbent. Furthermore, the invention relates to a method for removing or separating dissolved contaminants from a liquid and to a method for producing a liquid containing hemicellulose and/or an adsorbent containing lignin and/or other components. In particular the invention concerns the use of an adsorbent lignocellulosic material for removing dissolved contaminants from a liquid.
