Abstract: A fluid contactor is taught for mixing and reacting of fluids. Mixing is enhanced by providing a suitable residence time and suitable surface area contact by forming eddy flow within the fluid and thereby the formation of vortexes. Such a contactor does not require the use of mechanical mixers. The contact chamber of the present invention can enhance chemical modification by use of chemical modifiers such as ultraviolet lamps, by allowing the positioning of such modifiers adjacent the vortexes.

Abstract: A metal hydride is supplied into a reactor while being converted into fine particles. By injecting water from an injector, the metal hydride is hydrolyzed to generate hydrogen. The water supplied to the reactor is water generated by a fuel cell. This allows omission or a size reduction of a water tank for the hydrolysis, and therefore allows a size reduction of the system as a whole. It is possible to adopt a construction in which waste heat from the fuel cell is supplied to pyrolyze the metal hydride, a construction in which heat generated by the hydrolysis is used to pyrolyze another metal hydride, etc.

Abstract: Sour gas containing hydrogen sulphide has hydrogen sulphide absorbed therefrom in an absorbent in a vessel 4. A hydrogen sulphide rich gas stream is formed by desorbing hydrogen sulphide from the absorbent in a vessel 12. The resulting hydrogen sulphide rich gas stream is partially burned in a furnace 32. Resulting sulphur dioxide reacts therein with residual hydrogen sulphide to form sulphur vapor which is extracted in a condenser 44. Residual sulphur dioxide and sulphur vapor are reduced to hydrogen sulphide in catalyst stage 54 of a reactor 50. Water vapor is removed from the resulting reduced gas stream by direct contact with water in a quench tower 60. At least part of the resulting water vapor depleted gas stream is sent to the vessel 4 with the incoming sour gas stream.

Abstract: An apparatus removes water and organic compounds from waste streams such as contaminated soils and refinery tailings by a combination of thermal stripping and molecular decomposition. The apparatus includes at least one unit having a pipe which is preferably heated by induction heating and also having a transport arrangement. The transport arrangement includes a suitable motor and operates to move the waste stream material through the pipe and mix the material to provide uniform heat transfer from the heated pipe. The transport arrangement preferably includes an adjustment mechanism which allows adjustment of the rate at which material moves through the pipe for a given motor speed. The adjustment mechanism also adjusts the mixing provided by the transport arrangement. Several of the treatment units according to the invention may be connected in series to form a multistage device. The initial stages may be operated at temperatures capable of thermally stripping water and light hydrocarbons from the waste stream while the later units may be operated at temperatures to cause remaining organic material to decompose.

Abstract: A gas siphon type reactor (10) is used to carry out a three phase chemical reaction under pressure, such as the reduction of uranyl nitrate to uranous nitrate by hydrogen, in the presence of a catalyst made up of platinum on a silica carrier. The control of the pressure in the reactor (10) is provided by regulating the liquid and gas flow rates from a high-pressure separator (52), into which the liquid and the gas leaving the reactor (10) are routed. The liquid in the reactor (10) is tapped from a lateral branch pipe (32) fitted with a filter (36) and emerging in the upper area (30), behind a profiled wall (34).

Abstract: A molten metal reactor (10) quickly entrains a feed material in the molten reactant metal (16) and provides the necessary contact between the molten reactant metal and the feed material to effect the desired chemical reduction of the feed material. The reactor (10) includes a unique feed structure (24) adapted to quickly entrain the feed material into the molten reactant metal (16) and then transfer the molten reactant metal, feed material, and initial reaction products into a treatment chamber (12). A majority of the desired reactions occur in the treatment chamber (12). Reaction products and unspent reactant metal are directed from the treatment chamber (12) to an output chamber (14) where reaction products are removed from the reactor. Unspent reactant metal (16) is then transferred to a heating chamber (15) where it is reheated for recycling through the system.

Abstract: A multi-cyclone gas/solids separator with reduced solids re-entrainment is disclosed. The separator uses a plurality of cyclones spaced horizontally apart from adjacent cyclones to process flue gas containing residual catalyst fines. Each cyclone has a body that has a feed inlet end for admitting gas and entrained solids into an annular space defined by a sidewall of the cyclone body and a cylindrical gas outlet tube axially aligned with the cyclone body. A solids outlet at an opposing end of the cyclone body has a tangential outlet for solids and a minor amount of gas through a sidewall of the cyclone body. A gas reflux opening is axially aligned with the outlet tube. The plurality of cyclones share both a common catch chamber for solids discharged from the solids outlet, and a common manifold for gas and entrained solids. A plurality of shields are positioned in the catch chamber to inhibit discharge of solids from the tangential outlet of the adjacent cyclones into a vicinity of an inlet of the gas reflux opening.

Abstract: For the selective production of propylene from an olefinic C4 fraction, a process is implemented that successively comprises: 1) the selective hydrogenation of butadiene with isomerization of butene-1 into butene-2; 2) the separation by distillation of a mixture that is rich in isobutene and butene-1 at the top and a fraction that is rich in butene-2 at the bottom; 3) the skeletal isomerization of isobutene into n-butenes on the top fraction, with recycling in stage 1; and 4) the metathesis of the butene-2-rich fraction with ethylene. The advantage of this process is to produce in a very selective way polymerization-quality propylene from all of the olefinic compounds of a C4 fraction, including isobutene.

Abstract: A reactor containing a plurality of porous rotors is disclosed. A liquid sprayed in a direction from a rotating axis to the rotors is hit by the porous rotors, creating fine liquid particles, so that a mass transfer takes place between the surfaces of the liquid particles and a gas injected into the reactor, and thus a crystallization reaction is initiated. The crystallization reaction is confined by the amounts of the reactants contained in the liquid particles, and will stop as soon as one of the reactants is consumed, so that the resulting crystals can be controlled in nanometer level. The reactor of the present invention is also suitable for use in a liquid-liquid reaction, wherein two different liquids are separately sprayed in a direction from the rotating axis and hit by the porous rotors, and the resulting fine liquid particles of the two different liquids contact and react with each other, so that ultra fine particles are formed.
