Abstract:
An apparatus for introducing droplets of a monomer solution for production of poly(meth)acrylate into a reactor for droplet polymerization, comprising at least one channel or a dropletizer head, the channel or the dropletizer head being sealed at its base by a dropletizer plate, the dropletizer plate having holes through which the monomer solution is introduced into the reactor, and the dropletizer plate being configured such that holes that, in an axially symmetric dropletizer plate or in an annular dropletizer plate or in one configured as a ring segment, are not on a center line of the dropletizer plate or, in the case of a circular dropletizer plate, are not at the center of the dropletizer plate are aligned such that monomer solution is introduced through the holes into the reactor at an angle to the vertical, and the holes in the case of a radial alignment of axially symmetric dropletizer plates being aligned such that the angle at which the monomer solution is introduced into the reactor decreases in the direction of the axis of the reactor and, in the case of dropletizer plates arranged parallel to one another or of concentrically arranged dropletizer plates, each being aligned on a line parallel to the center line or line running concentrically about the center, such that the angle at which the monomer solution is introduced into the reactor is constant.

Abstract:
Systems and apparatus for ionic liquid catalyzed hydrocarbon conversion, such as alkylation, using vaporization to remove reaction heat from an ionic liquid reactor and to provide mixing therein, wherein hydrocarbon vapors are withdrawn from the ionic liquid reactor and the withdrawn hydrocarbon vapor is recovered by a hydrocarbon vapor recovery unit in fluid communication with the ionic liquid reactor for recycling condensed hydrocarbons to the ionic liquid reactor. Processes for ionic liquid catalyzed alkylation are also disclosed.
Abstract:
A hydrogen generator and method for generating hydrogen gas for a fuel cell stack. The hydrogen generator includes container, and a first reactant storage area configured to contain a liquid first reactant. The hydrogen generator also includes a reaction area and a solid second reactant within the reaction area, and a hydrogen outlet. The hydrogen generator further includes a flexible liquid delivery member extending into the reaction area and configured to deliver liquid reactant from the first reactant storage area to the reaction area. The flexible liquid delivery member includes a flexible portion that flexes to allow the delivery member to move with the solid second reactant as the second reactant is consumed.
Abstract:
A method and system for controlling an interface emulsion layer and mud layer within a desalter vessel includes injecting a water flow through a plurality of nozzles arranged about a piping circuit located in the brine water layer. Each nozzle is oriented toward an interior space of the desalter vessel and is arranged oblique to the piping circuit. The water flow through the plurality of nozzles causes a horizontal and vertical rotation of a volume of water that is effective for suspending solids in the water and promoting a collapse of the interface emulsion layer. The water velocity through each nozzle, which may be a recycled water flow, is preferably in a range of 1 to 3 fpm and each nozzle is preferably oriented at an angle of about 15° and 60° in a horizontal plane and a downward angle of about 15° and 60° in a vertical plane.
