Title: Very large-scale pressure swing adsorption processes
Inventor: WHYSALL MICHAEL
IPC: B01D53/047
Filed: 2001-01-29
Granted: 2006-03-28
Abstract: A process which overcomes limitations to the capacity of PSA units for a wide variety of gas separations by achieving capacities in excess of about 110 thousand normal cubic meters per hour (100 million standard cubic feet per day) in a single integrated process train and departs from the practice of using a purge step equal to or less than the duration of the adsorption step. By increasing the purge time relative to the adsorption step combined with supplying the purge gas for any adsorption bed in the train from one or more other adsorption beds and during the provide-purge step, the other adsorbent beds simultaneously provide the purge gas to essentially all adsorbent beds undergoing the purge step and the single train can provide for significant increases in capacity with a minimum loss in recovery or performance.

Abstract: A method for avoiding the precipitation of salts from a salt containing water stream prior to the stream reaching a supercritical water reactor is presented. The salt containing water stream is preferably kept at temperatures below supercritical conditions as the stream is transferred to the reactor. After the salt stream reaches the reactor the temperature of the salt stream is preferably raised to the appropriate temperature by mixing the salt stream, within the reactor, with a second stream that has been heated above the supercritical temperature of water. Alternatively, a method for preventing the clogging of the conduits upstream from the reactor may involve the mixing of two subcritical waste streams. One stream may include salts, the other preferably includes oxidizable material. The heat produced by the reaction of the oxidizable materials within the reactor preferably allows the mixture to remain at supercritical conditions for a time sufficient to oxidize substantially all of the oxidizable material.

Abstract: A method for analyzing a target seismic trace (100), generally comprises selecting other traces in source receiver space (114), not including traces from the same shot record that contains the target trace (122), and comparing the selected traces (118), to the target trace (115). The method generally includes setting a distance value indicative of the number of shot gathers (114), to be considered in conjunction with analyzing a target trace, specifying which traces from a plurality of shot records to compare to the target trace based on the distance value, calculating a first amplitude value associated with the amplitude of the target trace (100), calculating a second amplitude valve associated with the amplitudes of the specified comparison traces (100), and comparing the first amplitude value to the second amplitude value. The comparison and target traces can be analyzed (100), in various windows of time. The target trace is modified in a suitable manner if it is found to contain noise (100). The preferred method can be implemented in a seismic processing system (100), that is included onboard a seismic ship (100). Because the method does not require all of the seismic data to be acquired and then sorted before analyzed for noise, as is the case for many conventional trace editing techniques, the method of the preferred embodiment can be performed in near real or real time. As such, real time data quality control is possible.

Filed: 1999-08-17
Granted: 2011-10-11
Abstract: Transgenic microbial strains are provided which contain the genes required for PHA formation integrated on the chromosome. The strains are advantageous in PHA production processes, because (1) no plasmids need to be maintained, generally obviating the required use of antibiotics or other stabilizing pressures, and (2) no plasmid loss occurs, thereby stabilizing the number of gene copies per cell throughout the fermentation process, resulting in homogeneous PHA product formation throughout the production process. Genes are integrated using standard techniques, preferably transposon mutagenesis. In a preferred embodiment wherein multiple genes are incorporated, these are incorporated as an operon.

Abstract: A syringe has a retractable needle and a barrel having an open proximal end and an open distal end defining a receiver with an inward shoulder. The barrel has a hollow bore, an elongate plunger with a proximal end and a distal open end with a cavity therewithin. A stopper occludes the open end of the cavity. The syringe has an elongate hub with a proximal flange. The hub is within and sized for slidable movement within the receiver at the distal end of the barrel with the flange defining a distal end of a chamber. There is a sleeve sized to fit with a clearance about the hub disposed between the shoulder and the flange when the hub is in the receiver, the sleeve having a sharpened proximal end disposed against the flange. The needle has a pointed distal end and a proximal end connected to the passageway of the hub with the pointed end of the needle extending outwardly. There is a spring disposed about the hub compressed to provide a bias between the receiver and the flange so that when a force greater than required to expel fluid from the chamber is applied, the plunger causes the cutting surface to cut through the flange and stopper and expose the cavity to allow the spring to urge the hub into the cavity in the plunger and retract the needle to a position within the syringe.

Title: Fcc feed injection using subcooled water sparging for enhanced feed atomization
Inventor: SWAN GEORGE ALEXANDER
IPC: B05D1/02
Filed: 1999-12-03
Granted: 2010-06-15
Abstract: Atomization of a high boiling point, hot liquid, such as a hydrocarbon feed oil for a fluid cat cracker, is enhanced by injecting subcooled water into the hot liquid, to form a two-phase fluid of the liquid and steam, upstream of the atomization. The hot liquid is at conditions of temperature and pressure effective for the injected, subcooled water to vaporize into steam, when the water contacts it. Typically this means that the hot liquid is hotter and at a lower pressure than the water. In an FCC process, the subcooled water is sparged into the flowing hot oil in a conduit (34) in a riser feed injector (10). This produces a spray of hot oil in the riser reaction zone (22) in which the oil drops are smaller and more uniformly distributed in the spray.
