Abstract: A system for abating undesired component(s) from a gas stream containing same, such as halocompounds, acid gases, silanes, ammonia, etc., by scrubbing of the effluent gas stream with an aqueous scrubbing medium. Halocompounds, such as fluorine, fluorides, perfluorocarbons, and chlorofluorocarbons, may be scrubbed in the presence of a reducing agent, e.g., sodium thiosulfate, ammonium hydroxide, or potassium iodide. In one embodiment, the scrubbing system includes a first acid gas scrubbing unit operated in cocurrent gas/liquid flow, and a second “polishing” unit operated in countercurrent gas/liquid flow, to achieve high removal efficiency with low consumption of water. The scrubbing system may utilize removable insert beds of packing material, packaged in a foraminous containment structure. The abatement system of the invention has particular utility in the treatment of semiconductor manufacturing process effluents.

Abstract: To ensure a performance-based regulation of a fuel cell, the use of fuel-mixtures with a defined flow is required. Mixtures of this type are formed by pumping water through a hollow body, which, at least in certain sections, has a wall formed of porous material. The fuel is pumped into a chamber on the other side of the porous wall, at a defined flow rate. As a result of the pressure difference, the fuel permeates the porous wall over its entire surface into the water flowing past on the other side of said porous wall, thus creating a homogeneous mixture. In the corresponding device, at least certain segments of the hollow body have a porous wall. A device of this type is preferably used in direct methanol fuel cells, for which the operating temperature and the operating pressure can be predefined.

Abstract: A compact, continuous-flow synthesis device for the production of dimeric hydrocarbon species by reacting unsaturated hydrocarbons such as alkenes and alkynes with atomic hydrogen or free radicals generated by the dissociation of molecular hydrogen or organics such as alkanes. The dissociation is carried out in a module either by the electric discharge between a pair of parallel, annular, flat disc, high-voltage electrodes or by the radiation between a pair of parallel, toroidal ultraviolet lamps. The reactant to be dissociated flows radially inward from the module periphery between the pair of electrodes or the pair of ultraviolet lamps, and reaches the axis of the annulus or torus in the dissociated state. Unsaturated hydrocarbons in the dispersed phase injected vertically down this axis react with the dissociated species in a collision chamber surrounding the dissociation module to form residual free radicals. Cooling the residual free radicals then converts them to condensed dimeric products in a collection basin adjacent to the collision chamber. Many dimeric species, such as 2,2,3,3-tetramethylbutane, can be produced from different starting materials. The device also generates dimeric products from the reaction of free radicals alone in the absence of unsaturated hydrocarbons.

Abstract: A separation capillary in a capillary electrophoresis apparatus is less than 20 microns high to restrict the flow velocity profile of the EOF to being substantially parabolic. The capillary is preferably rectangular with an aspect ratio of at least 2:1, and preferably at least 10:1, in order to increase bulk flow. Hydrostatic back pressure is applied to the capillary to reduce or cancel the EOF. The back pressure is preferably at least 50% as strong as the forward-directed EOF in order to reduce EOF, and thereby to increase resolution.
