  • Patent number: 10260661
    Abstract: The invention relates to line elements (600) consisting of a multi-layer inner element (IE) and an outer element (AE), wherein the inner element (IE) and the outer element (AE) are in contact with each other at points, at lines, over part of the surfaces thereof, or over the full surfaces thereof. Furthermore, a frictional contact protection means extending over the component length is provided, or a frictional layer (121) is provided in the contact region of the inner element (IE) and the outer element (AE). The wear of the outer element (AE) caused by friction can thereby be minimized.

  • Patent number: 9643122
    Abstract: A device and method for separating off carbon dioxide is provided, including an absorption unit, desorption unit assigned thereto and a separation unit for separating off salts from a scrubbing solution. The absorption and desorption units are connected to each other via a first conduit for a regenerated scrubbing solution and a second conduit for a loaded scrubbing solution. The separation unit includes a crystallizer for forming salt crystals and a first separator unit on the downstream side for separating off salt crystals. A separation unit is provided for separating off salts from a scrubbing solution, having a crystallizer and a first separator unit downstream thereof. The crystallizer has a crystallization chamber for forming salt crystals and a countercurrent classifier for separating salt crystals according to particle size. A first branch conduit is connected to the crystallization chamber, which opens out into the countercurrent classifier via a second separator unit.

  • Patent number: 9527037
    Abstract: A method for processing an amine-based solvent contaminated by the introduction of sulfur oxides is provided. A potassium compound is introduced into a contaminated solvent, and the contaminated solvent is cooled so that a solubility of a potassium sulfate becomes less than a specified concentration of potassium sulfate. Further, an oxidizing agent is introduced into the contaminated solvent so that a potassium sulfite is oxidized to potassium sulfate. The potassium sulfate is filtered out, wherein a prepared solvent is formed. Further, a device for processing an amine-based, sulfur oxide-contaminated solvent is provided.

  • Publication number: 20150375137
    Abstract: A device and a method are for treatment of an amino acid salt solution that is contaminated with carbon dioxide and is an absorbent for carbon dioxide from a flue gas of a combustion, and includes a reaction process, a following filtration process and a following dissolution process. In the reaction process, carbon dioxide is introduced into the amino acid salt solution, and the amino acid salt solution is cooled. In this case crystalline carbonate and crystalline amino acid precipitate out. In the filtration process, the crystalline carbonate and the crystalline amino acid are filtered off. In the dissolution process the crystalline carbonate and the crystalline amino acid are dissolved in a solvent and a treated amino acid salt solution is thereby recovered.

  • Publication number: 20150139876
    Abstract: A method for depositing carbon dioxide from a flue gas (RG) of a combustion system is provided. A scrubbing solution (A) with an amine-containing absorption agent is mixed together with ozone and/or hydrogen peroxide as an oxidizing agent for nitrite. The flue gas (RG) is brought into contact with the scrubbing solution (A) prepared in this manner, whereby carbon dioxide contained in the flue gas is absorbed, and the scrubbing solution (A) is then thermally treated, whereby the carbon dioxide is desorbed. A corresponding scrubbing solution (A) with an amine-containing absorption agent and with ozone and/or hydrogen peroxide as an oxidizing agent for nitrite is also provided.
