  • Patent number: 9375676
    Abstract: A recovery apparatus of carbon dioxide includes: an absorption column contacting a carbon dioxide-containing gas into contact with an absorbing liquid and allowing the absorbing liquid to absorb carbon dioxide; a regeneration column for regenerating the absorbing liquid to release carbon dioxide; a circulation system which circulates the absorbing liquid to flow from the absorption column and return to the absorption column through the regeneration column; and a steam supply system which generates steam available for a heat source that regenerates the absorbing liquid, using the absorbing liquid that returns to the absorption column and/or the absorbing liquid in the absorption column, and supplies the steam to the regeneration column. High temperature steam is generated from the absorbing liquid and is provided to the regeneration column to use as a heat source for regenerating the absorbing liquid.

  • Publication number: 20160001223
    Abstract: The carbon dioxide recovery method and apparatus are capable of reducing regeneration energy and operating cost, and structurally advantageous. An absorber has first and second absorbing sections where a gas is supplied through the first absorbing section to the second absorbing section. A regenerator has first and second regenerating sections. The first regenerating section has an external heater and the second regenerating section is heated by the gas discharged from the first regeneration section. The absorbing liquid circulates between the second absorbing section and the first regenerating section in a circulation system, and a branch system allows a part of the absorbing liquid to flows from the second absorbing section through the first absorbing section and the second regenerating section successively to the first regenerating section. The recovery gas discharged is compressed, and its heat is recovered and supplied to the regenerator by heat exchange with the absorbing liquid.

  • Publication number: 20130305924
    Abstract: A recovery apparatus of carbon dioxide comprises: an absorption column which brings a gas containing carbon dioxide into contact with an absorbing liquid and allows the absorbing liquid to absorb carbon dioxide; a regeneration column for regenerating the absorbing liquid, by causing the absorbing liquid having carbon dioxide absorbed in the absorption column to release carbon dioxide; a circulation system which circulates the absorbing liquid so that the absorbing liquid flowing from the absorption column returns to the absorption column through the regeneration column; and a steam supply system which generates steam available for a heat source that regenerates the absorbing liquid, using at least one of the absorbing liquid that returns to the absorption column by the circulation system and the absorbing liquid in the absorption column, and supplies the steam to the regeneration column.

  • Patent number: 8545579
    Abstract: A gasification furnace 2 is divided into a plurality of gasification furnace units 2a and 2b each of which has an inlet 15a, 15b on a lower portion at a longitudinally upstream end in a direction of travel of raw and bed materials and has an outlet 16a, 16b on an upper portion at a longitudinally downstream end in the direction of travel. The outlet 16a is connected to the inlet 15b. The inlet 15a is fed with a raw material and a hot bed material from a materials separator 8. The inlet 15b is also fed with the hot bed material from the material separator 8. The outlet 16b is connected to a combustion furnace 5.
