Patent CA-2387690-C (CA)
Inventor: MUEHLEN HEINZ-JUERGEN
IPC: C10B53/02

Granted: 2010-12-14
Abstract: The aim of the invention is to provide a method for gasifying organic materials which is simple to carry out and requires minimal equipment and which produces an undiluted gas of high calorific value. The inventive method should eliminate the need to use fluid beds and heat exchangers with high temperatures on both sides, with the heat being transferred from the furnace to a heat-carrying medium in a particularly defined way. To this end, the feed material (101) is divided into a volatile phase and a solid carbon-containing residue in the pyrolysis reactor (104) by circulating a hot heat-carrying medium. After the reaction agent (109) has being added, said volatile phase is converted into the product gas by further heating in the reaction area (reformer) (107), also using the heat-carrying medium. The solid, carbon-containing residue is separated from the heat-carrying medium in the separating stage (121) and burnt in the furnace (105). The heat-carrying medium is heated by the waste gases of the furnace (105) in the heating area (117) and then returned to the reformer (107) and then the pyrolysis reactor (104).

Abstract: With the present invention, asynchronous processor circuit can be implemented with a simplified circuit by improving a display's synchronization stability, and by setting a pulse width of a vertical synchronizing signal to be integral multiple of that of the frequency of the horizontal synchronizing signal.      In a synchronous processor circuit in FIG. L, an LPF 1 receives an externally provided composite signal 5, and a vertical synchronization separating signal 6 is separated therefrom; a 1/2 frequency divider circuit 4 outputs a vertical phase detection signal 9 obtained by dividing the frequency synchronization separating signal 6 into 1/2; a phase delay part 2 receives the composite signal 5 and outputs a plurality of horizontal synchronizing signals 19 to 24 each differently delayed in phase; and a vertical synchronizing signal reproduction circuit 3 uses the vertical synchronization separating signal 6 and the plurality of phase-delayed horizontal synchronizing signals 19 to 24 to output a vertical synchronizing signal 8 having the phase relationship determined with respect to the horizontal synchronizing signal.

Granted: 2006-04-11
Abstract: An ion separation instrument (600) includes an ion source coupled to at least a first ion mobility spectrometer (34) having an ion outlet coupled to a mass spectrometer (36). In one embodiment, the ion source includes a molecule separation instrument (602) operable to separate ions in time according to a molecular characteristic such as ion retention time. The resultant instrument is thus operable to provide molecular information separated in time as functions of retention time, ion mobility and ion mass/charge. In another embodiment, the ion separation instrument includes first and second ion mobility instruments disposed in a cascade arrangement between the ion source and mass spectrometer, wherein the two ion mobility instruments are operable to separate ions in time each according to different ion mobility functions.  For example, the two ion mobility instruments may have different flight tube lengths, operate at different temperatures, operate in the presence of different electric fields and/or operate in the presence of different gases.  The resultant instrument is thus operable to provide molecular information separate in time according to at least two different functions of ion mobility as well as ion mass/charge.

Abstract: A method of downhole cyclone oil/water separation is described. Firstly, place a cyclone separator downhole in an oil well producing a mixed stream of oil, water and gas. The cyclone separator includes a separation chamber wherein liquids of differing densities are separated, at least one mixed liquids inlet through which liquids pass into the separation chamber, a first outlet for liquids of a first density range to pass from the separation chamber and a second outlet for liquids of a second density range to pass from the separation chamber. Secondly, connect the first outlet to a recovery conduit extending to surface. Thirdly, connect the second outlet to a disposal conduit extending to a selected disposal site. Fourthly, connect the mixed liquids inlet to pumping means and pump a mixed stream of oil, water and gas into the separation chamber of the cyclone separator. The mixed stream is separated in the separation chamber into a recovery stream of oil with a reduced water content which flows out of the first outlet and along the recovery conduit to the surface and a disposal stream of mainly water which flows out of the second outlet and along the disposal conduit to the selected disposal site. The described method is particularly for oil wells in which the fluids being separated contain gas.
