  • Patent number: 10519045
    Abstract: Seawater is deaerated using a rotating packed bed device having one or more rotatable packing rings within a housing, a liquid inlet for infusing seawater into an interior region defined by the packing rings, a gas outlet for accepting gas which has passed radially inwardly through the packing rings and removing the gas from the interior region, and a liquid outlet for removing a deaerated seawater stream from the housing. A shaft coupled to a motor drives the packing rings causing the packing rings to rotate. The feed seawater stream passes radially outwardly through each of the packing rings thereby forming the deaerated seawater stream having a lower concentration of oxygen, air and/or carbon dioxide therein than the feed seawater stream and a gas stream having been removed from the feed seawater stream. The deaerated seawater stream is then injected into a hydrocarbon producing reservoir in an EOR process.

  • Patent number: 8420301
    Abstract: A method for forming a wiring pattern by laser irradiation includes the steps of coating a light-sensitive material on a substrate to form a light-sensitive layer, irradiating a laser beam on the light-sensitive material of the substrate to form a pattern including an exposed region exposed to laser irradiation and an unexposed region unexposed to laser irradiation, and forming a metallic wiring pattern by immersing the substrate into a solution having a plurality of metallic nano-particles. The metallic nano-particles are easily bonded to the straighter molecular structure of the light-sensitive material in the exposed region for forming a conducting wiring pattern. The laser irradiation method has advantages such as high-power, high-density, high-directionality and monochromaticity, such that product quality can be effectively controlled. Moreover, the laser irradiated light-sensitive material can form a molecular structure that is easily bonded to the metallic particles.

  • Patent number: 8197670
    Abstract: A process is disclosed using a dispersion of supercritical fluid and oil to upgrade a hydrocarbon feedstock such as a heavy oil into an upgraded hydrocarbon product or synthetic crude with highly desirable properties such as low sulfur content, low metals content, lower density (higher API), lower viscosity, lower residuum content, etc. The process utilizes a capillary mixer to form the dispersion. The process does not require external supply of hydrogen nor does it use externally supplied catalysts.
