  • Patent number: 7785399
    Abstract: Systems and processes utilize one or more methods of providing overhead waste process heat to increase the feed temperature of the hot solvent stripping regeneration loop in an acid gas removal process. A heated rich solvent stream can be the primary feed for the hot solvent stripping regeneration loop, and one or more slip streams can be heated and then combined with the heated rich solvent stream to form a combined rich solvent stream prior to further processing in downstream units to remove acid gas from the solvent. A first slip stream can be heated in a stripper gas heat exchanger by heat exchange with a stripped gas stream. A second slip stream can be heated in a regenerator exchanger by heat exchange with an acid gas stream. A third slip stream can be heated in a recycle gas exchanger by heat exchange with a compressed recycle gas stream.

  • Publication number: 20100089450
    Abstract: Disclosed herein is a concentrating photovoltaic system utilizing a lens/reflector array to spatially divide the incident sunlight into separate incoherent beams, and a principle optical element to superpose the separate beams that undergo near-field diffraction/transmission, and form a uniform illumination pattern on the photovoltaic (PV) cell with similar shape and size. The array and principle optical element can be flexibly disposed in the system as long as the near-field diffraction condition is satisfied. The PV cell is disposed close to the focus of the principle optical element, and the concentrated illumination pattern on the PV cell is nearly a geometric projection of individual lens/reflector in the array. The size of the pattern is controlled by changing the focal lengths of the array and principle optical element, the distance between them, and the size of individual lens/reflector in the array.

  • Publication number: 20100062928
    Abstract: The present invention provides a doped titanium oxide having visible light-responsiveness whose structure is specified, and a simple production method thereof. By burning with heat a layered structure composite laminated alternately with polymer and the titania, which is obtained using basic polymer having amino group(s) and water-soluble titanium compound, carbon atoms and nitrogen atoms in the polymer are, doped to the crystalline surface of titanium oxide. As making the polymer complex with metal ions beforehand, the metal ions can be also doped to the titanium oxide.

  • Publication number: 20090155591
    Abstract: The present invention provides an organic-inorganic composite microparticle containing a metal complex, which has multiple needle-like structures on the surface and includes the metal complex therein; and a method for producing the microparticle in a simple manner. By using a metal complex made from a polymer having a linear polyethyleneimine chain and a metal ion, a composite microparticle which has the metal complex in silica and has a micro-needle-like structures on the surface can be derived, thus a microparticle having needle-like structures on the surface is obtained, wherein there are nano-sized multiple needle-like structures on the surface of the microparticle. The needle-like structures on the surface and the spatial structure of the resulting microparticle can be controlled by varying the species of the metal ion and the types of the substrate medium for the metal complex.
