Abstract: The carbon dioxide recovery method and apparatus are capable of reducing energy for regenerating the absorbing liquid and operating cost. An absorption column has first and second absorbing sections that a gas is supplied through the first absorbing section to the second absorbing section and the absorbing liquid absorbs carbon dioxide. A regeneration column regenerating the absorbing liquid has first and second regenerating sections. The first regenerating section has an external heating implement and the second regenerating section is heated by the gas discharged from the first regeneration section. Circulation mechanism has a circulation system circulating the absorbing liquid between the second absorbing section and the first regenerating section, and a branch path branched from the circulation system.

Abstract: A carbon dioxide recovery method and a recovery apparatus are capable of decreasing energy for regenerating an absorbing liquid to reduce operating cost. The apparatus has an absorption column that the absorbing liquid absorbs carbon dioxide of a gas, a regeneration column heating and regenerating the absorbing liquid with discharge of carbon dioxide, and a circulation system circulating the absorbing liquid. The absorbing column has first and second absorbing sections, and gas is supplied to the second absorbing section through the first absorbing section. The regeneration column has a first regeneration section having an external heating implement and a second regeneration section heated by the gas discharged from the first regeneration section. The circulation system has a first circulation path circulating between the first absorption section and the second regeneration section and a second circulation path circulating between the second absorption section and the first regeneration section, separately.

Abstract: A semiconductor device includes an intermediate layer provided between a semiconductor element and a heat sink. The intermediate layer moderates thermal stress resulting from a difference between thermal expansion of the semiconductor element and thermal expansion of the heat sink arising due to heat produced by the semiconductor element. This thermal stress moderation reduces warping of the semiconductor device as a whole.
