  • Publication number: 20120070348
    Abstract: An apparatus for mass transfer of a gas into a liquid, including a tank that defines a chamber for receiving the gas, and at least one surface provided within the chamber. Each surface has an inner region, an outer region and an edge adjacent the outer region. Each surface is configured to receive the liquid at the inner region and rotate such that the liquid flows on the surface from the inner region to the outer region, and, upon reaching the edge of the surface, separates to form liquid particles that move outwardly through the gas in the chamber. The liquid particles are sized so that the gas is absorbed by the liquid particles to produce a mixed liquid saturated with the gas during a brief flight time of the liquid particles through the chamber.

  • Patent number: 8119084
    Abstract: A reactor for the autorefrigerant alkylation process has a cylindrical upright reactor vessel with the inlet for the refrigerant reactant and the sulfuric acid at its lower end and a series of inlets for the olefin reactant at vertically spaced intervals up the length of the reactor. An extended, sinuous flow path for the reactants is provided by means co-acting baffles co-acting baffles having, alternately along the length of the reactor, central flow passages and peripheral flow passages for the reaction mixture to define sequential reaction zones in which alkylation takes place. The baffles interact with a rotary mixer with multiple impellers located on the reactor axis. The reaction mixture flows alternately towards and away from the reactor walls in the sequence of serial reaction zones within the reactor to promote mixing of the isoparaffin reactant with the acid catalyst.

    Abstract: The invention relates to a mixer reactor of the rotor-stator type. This mixer reactor comprises a substantially rotationally symmetric housing which has a distributing chamber, a mixing chamber, a front plate that modifies the cross-section of the housing between these two chambers, and there are separate inlets into the mixing chamber for at least two substances and an outlet for removing the mixed material or product. The inlet for the first substance is provided in the axis of rotation of the mixing chamber. Two or more channels are aligned radially outward from this inlet, and the first substance is transported through these channels and into the mixing chamber. The inlet for the at least second substance is constructed in the form of a plurality of openings in the front plate, these inlet openings being are arranged rotationally symmetrically to the axis of rotation. Each of these inlet openings for the at least second substance has a corresponding pin which can be displaced in the axial direction.
