  • Publication number: 20100145115
    Abstract: The present invention relates to a method and system for treatment of a flow of fluid hydrocarbons containing water. The flow of hydrocarbons is introduced into a mixer (7) where it is mixed with liquid carbon dioxide (6) before the resulting mixture is cooled in a cooler (8) and conveyed to a reactor (9), in which all water present in the hydrocarbon flow will be in the form of hydrates, and said flow is conveyed to a pipeline (11) to be transported to its destination. The cooling system may comprise a choke or a mixer where the warm hydrocarbon flow is mixed with a cold flow of hydrocarbons.

  • Publication number: 20080273208
    Abstract: This invention relates to an interference filter, especially for use in gas detection with infrared light within a chosen range, comprising at least two essentially parallel and partially reflective surfaces with a chosen distance between them thus defining a cavity delimited by the reflecting surfaces between which the light may oscillate, and wherein at least one of said surfaces is partially transparent for transmission of light to or from said cavity. The filter comprises a first transparent material having a high refractive index, e.g. silicon, positioned in at least a part of said cavity, and at least one of said reflective surfaces being divided into a three dimensional pattern with varying shift relative to its plane, thus to provide a position dependent resonance condition between them for separation of different wavelengths in the light.

  • Publication number: 20070260030
    Abstract: Polybranched organic/inorganic hybrid polymer and method for its manufacture. The hybrid polymer has the form of an inorganic core carrying organic branches. The core is first prepared by controlled hydrolysis and condensation of a silane with a structure: X—B—Si(—Y)3 in which X?NP1 R2, while R1, R2 are chosen among hydrogen, alkyl and aryl, or R1, R2 are chosen among condensation products, addition products of one or more type of chemical substances such as acids, alcohols, phenols, amines, aldehydes or epoxides. B is a linkage group chosen among alkylene and arylene which may include oxygen, nitrogen, sulphur, phosphorous, silicon and boron. Y is chosen among hydrolyzable residues such as alkoxy, carboxyl, and halogen. The organic branches are developed by substituting N—H hydrogen atoms in the X—B group by reactions that are typical for primary and secondary amines, and/or by adding an acid that causes an addition to the N atoms of the X—B group in the core.
