20090110599 | METHODS OF OPERATING FILM SURFACE REACTORS AND REACTORS EMPLOYING SUCH METHODS - In new methods of operating surface reactors, and new reactors employing such methods, the reactor comprises a cylindrical rotor and a cylindrical stator coaxial with one another with respective cylindrical faces forming an annular reaction chamber between them, the chamber being filled with air or inert gas constituting a shear transmitting fluid. The volume of the reactants, one of which at least must be in liquid state, fed into the chamber is only such that they will immediately be spread out under centrifugal force on the stator surface by the shear transmitting fluid in the form of a film of thickness not more than 150 micrometers, preferably not more than 120 micrometers, and more preferably less than 100 micrometers. The rotor is rotated at high speed, usually about 30,00 to 80,000 rpm, and at these speeds molecular clusters which normally slow down one on one molecular encounters between the reactant molecules, are disrupted by the high shear to facilitate forced, uniform molecular interdiffusion, so that the molecules more aggressively and quickly interact with one another with considerably increased rates of reaction, e.g 100 to 1,000 times increase. This use of an intermediate shear transmitting gaseous fluid gives flexibility in the radial dimension of the reaction chamber, which can be 1 mm or larger, avoiding the need for a reaction chamber of radial dimension corresponding to the desired film thickness and its attendant difficulties, due for example to differential expansion of the rotor and stator with rotation and temperature changes. | 04-30-2009 |
20090110600 | METHODS OF OPERATING FILM SURFACE REACTORS AND REACTORS EMPLOYING SUCH METHODS - In new methods of operating surface reactors, and new reactors employing such methods, the reactor comprises a helical reaction chamber formed as a coil surrounding a tubular support, or a groove machined in a cylindrical body. The passage is supplied with a high velocity flow of air or inert gas constituting a shear transmitting fluid that immediately spreads the reactants, one of which at least must be in liquid state, as they are fed into the chamber against the radially outermost wall of the chamber into a film of thickness not more than 150 micrometers, preferably not more than 120 micrometers, and more preferably less than 100 micrometers. The fluid is supplied at velocities of between 1 and 100 meters per second, preferably between 6 and 20 meters per second. At these speeds and corresponding centrifugal force, molecular clusters, which normally inhibit one on one molecular diffusion reaction between the reactant molecules, are disrupted by the highly sheared fluid to facilitate forced molecular interdiffusion, so that the molecules more aggressively and quickly interact with one another with considerably increased rates of reaction, e.g. 100 to 1,000 times increase. This use of an intermediate shear transmitting fluid traveling at high velocity in a circular path gives flexibility in the radial dimension of the reaction chamber, which can be as large as 10 mm radially and 6 mm longitudinally and provides one open surface of the sheared film of the reagents. | 04-30-2009 |
20090208389 | SPINNING TUBE IN TUBE REACTORS AND THEIR METHODS OF OPERATION - A spinning tube in tube reactor has the usual elongated transverse annular cross section reaction passage through which reactants pass to force reaction between them; the passage being between the rotor tube exterior surface and the stator tube interior surface. The radial dimension of the annual passage should be keep as uniform as possible so as not to cause unwanted variations in the reaction. This has proven difficult in prior constructions owing to the small radial dimension (e.g. 50-300 micrometers) and inevitable manufacturing tolerances in the bearings supporting the rotor. In apparatus of the invention the rotor is suspended within the stator passage by a flexible connection between the drive motor shaft and the rotor and uniformity is maintained by the so-called hydrodynamic effect which will become operative in such a narrow passage. Thus, if any part of the rotor surface moves radially from the central position closer to the stator surface the liquid viscosity produces a force that moves the rotor back to the central position. Preferably the flexible connection consists of two serially connected flexible connectors. | 08-20-2009 |
20120152508 | HEAT EXCHANGE APPARATUS - The heat exchange apparatus provides a flow passage for the heat exchange fluid comprising a succession of flow passage chamber portions separated from one another by intervening throttle forming passage portions of smaller cross section, and therefore of smaller flow capacity, transverse to the flow direction, so that the heat exchange fluid moves at a higher velocity in the throttle forming portions than in the chamber portions. The fluid is moved at a rate such that its velocity in the throttle forming portions is high enough to reduce the thickness of the fluid boundary layer on the passage wall and thereby facilitate the heat exchange. Alternatively, or in addition, the velocity is high enough to at least reduce the rate of fouling of the passage wall surface. Alternatively, or in addition, the fluid flows as eddy vortices, the spacing of the chamber portions along the passage being such that wake interference flow is established which enhances the rate of heat exchange. The exchanger is intended principally for use in combination with a spinning tube in tube reactor with a very small annular cross section reaction passage between them, the exchanger also being of tubular form with the stator tube constituting a wall of the heat exchanger. | 06-21-2012 |
