20130125839 | U-TUBE VAPORIZER - A vaporizer includes a plurality of U-shaped tubes contained in a vessel and are arranged in at least one plane. The vessel is closed at one end by a plate having openings adapted to mate with the end of the U-shaped tubes, and there is a dome covering the plate on the opposite side of the tubes. The dome is bounded by a wall forming an inlet chamber and an outlet chamber, the inlet chamber being split into two parts by a partition perpendicular to the plane of the tubes and to the wall to form a chamber for admitting liquid between the plate and the partition and an auxiliary chamber on the other side of the partition. The auxiliary chamber is configured to receive liquid from the admission chamber such that liquid from the outside arriving in the admission chamber enters the tubes via the bottom openings only. | 05-23-2013 |
20120285197 | PROCESS AND UNIT FOR THE SEPARATION OF AIR BY CRYOGENIC DISTILLATION - An air separation unit having a medium-pressure column, a low-pressure column, a chamber, a heat exchanger, a bottom condenser of the low-pressure column and a condenser placed in the chamber is provided. The air separation unit also includes an expansion device configured to expand oxygen-rich liquid from the bottom of the low-pressure column before the oxygen-rich liquid is introduced to the chamber and a compressor configured to compress the gas from the chamber, wherein the compressor is downstream of the chamber and upstream of the low-pressure column. | 11-15-2012 |
20120279239 | Method and Device for Low-Temperature Cooling/Liquefaction - The invention relates to a method for low-temperature cooling/liquefaction of a working fluid, in particular a working fluid including helium or consisting of pure helium by means of a refrigerator/liquefier that includes a working circuit provided with a compressor station and a cold box. The refrigerator/liquefier subjects the working gas within the working circuit to a cycle that includes, in series: compressing the working fluid within the compressor station, cooling and decompressing the working fluid in the cold box, and heating the working fluid with a view to the return thereof to the compressor station. The compressor station includes one or more compression levels, each one using one or more compressors mounted on landings. The method is characterized in that the refrigerator includes a device for injecting a seal gas that is separate from the working fluid on at least one landing of the compressor(s) so as to form a gas seal that guides the working fluid leaks, coming from the working circuit, to an area for recirculating and returning the fluid into the working circuit. | 11-08-2012 |
20120248377 | Catalytic Reactor Including a Catalytic Cellular Structure and at least One Structural Element - The invention relates to a catalytic reactor including at least two catalytic cellular architectures and at least one structural element, inserted between the two catalytic cellular architectures, in which the entire outer perimeter is in contact with the inner wall of the reactor, the cellular architecture and the structural element being arranged coaxially. | 10-04-2012 |
20120171629 | Flameless Combustion Burner - A burner has a fuel/oxidant nozzles and a pair of dynamical lances spaced on either side thereof that inject a jet of fuel and primary oxidant along a fuel injection axis, and jets of secondary oxidant, respectively. Jets of actuating fluid impinge against the jets of secondary oxidant to fluidically angle the jets of secondary oxidant away from the fuel injection axis. The action of the angling away together with staging of the oxidant between primary and secondary oxidant injections allows achievement of distributed combustion conditions. | 07-05-2012 |
20120157731 | Multistage Prereforming - A pre-reforming process is provided. This process includes heating a first stream containing heavy hydrocarbons to a first temperature, then introducing the heated first stream into a first pre-reforming chamber, thereby producing a first pre-reformed stream. This process also includes heating the first pre-reformed stream to a second temperature, then introducing the heated first pre-reformed stream into a second pre-reforming chamber, thereby producing a second pre-reformed stream. This process also includes heating the second pre-reformed stream to a third temperature, then introducing the heated second pre-reformed stream into a third pre-reforming chamber, thereby producing a third pre-reformed stream. | 06-21-2012 |
20120018410 | Microwave Plasma Generating Plasma and Plasma Torches - The invention relates to a plasma generating device that comprises at least one very high frequency source (>100 MHz) connected via an impedance adaptation device to an elongated conductor attached on a dielectric substrate, at least one means for cooling said conductor, and at least one gas supply in the vicinity of the dielectric substrate on a side opposite to that bearing the conductor. The invention also relates to plasma torches using said device. | 01-26-2012 |
20110220482 | Heat Exchanger - The present invention relates to the vaporization of a liquid by exchanging heat with a second fluid by means of a heat exchanger of the vertical plate type. It applies in particular to air distillation installations. | 09-15-2011 |
20100322843 | Method For Burning Carbonated Fuels With Combustion Smoke Filtration Before Compression - A process for the combustion of a carbon-containing fuel, wherein the flue gases are filtered so as to achieve a solid particle concentration of less than 1 mg/m | 12-23-2010 |
20100319804 | DEVICE FOR FILLING AND DISTRIBUTING GAS AND ASSEMBLY COMPRISING SUCH A DEVICE - Device for filling and distributing gas comprising a body intended to be placed in the orifice of a pressurized-gas storage reservoir, a gas withdrawing circuit running between an upstream first end intended to be connected to the inside of the reservoir and a downstream second end intended to be connected to a user of the gas, the withdrawing circuit comprising a pressure regulator, a low-pressure chamber and an isolation valve positioned in series in that order from upstream to downstream, the low-pressure chamber being connected to a passage for discharging the gas to the outside of the device via a safety relief valve sensitive to the pressure in the low-pressure chamber and designed to close off the discharge passage when the pressure in the low-pressure chamber is below a first threshold, to open the discharge passage when the pressure in the chamber is higher than the first pressure threshold and below a second pressure threshold, and to close the discharge passage when the pressure in the chamber is higher than the second pressure threshold. | 12-23-2010 |
