| 20080196763 | AMMONIA VAPORIZATION SYSTEM USING NON-FLUE GAS INTERMEDIATE HEAT TRANSFER MEDIUM - Methods and apparatus for generating a vapor to be injected into a flue gas stream are described. The apparatus includes a fluid vaporization and injection assembly including an input for receiving a non-flue gas, e.g., clean, fluid heat transfer medium, e.g., air; a first sealed coil having an input and an output through which a fluid, such as ammonia, to be vaporized is passed; and a second sealed coil having an input and an output through which a heated second fluid, such as water or steam, is passed. The second sealed coil is arranged to transfer heat from the heated second fluid to the non-flue gas fluid heat transfer medium. The first sealed coil is arranged to absorb heat from the non-flue gas fluid heat transfer medium. An injection unit is coupled to an output of the first sealed coil for injecting the vaporized fluid into a flue gas stream. | 08-21-2008 |
| 20100126590 | Particulate flow control process - A process is disclosed for providing a flow of particulate matter such as a catalyst to a reactor, comprising intermittently adding said particulate matter and a diluent to a mixing tank, and continuously withdrawing a slurry of particulate matter in diluent from the mixing tank for introduction into the reactor, wherein prior to each addition of particulate matter and diluent to the mixing tank, the concentration of particulate matter in the diluent already in the mixing tank is measured or calculated, and the amount of particulate matter and diluent subsequently added is measured so as to achieve the same concentration at the end of the addition as that measured or calculated prior to the addition. Preferably measurement of the amount of particulate matter and diluent added to the mixing tank is carried out before any diluent is added to the particulate matter. | 05-27-2010 |
| 20100163112 | GAS SUPPLY UNIT, SUBSTRATE PROCESSING APPARATUS AND SUPPLY GAS SETTING METHOD - A gas supply unit, for supplying a gas into a processing chamber in which a substrate is processed, includes a plurality of gas supply sources, a mixing line for mixing a plurality of gases supplied from the gas supply sources to make a gaseous mixture, a multiplicity of branch lines for branching the gaseous mixture to be supplied to a multiplicity of places in the processing chamber, and an additional gas supply unit for supplying a specified additional gas to a gaseous mixture flowing in at least one branch line. The gas supply unit also includes pressure gauges and valves for adjusting gas flow rates in the branch lines, respectively, and a pressure ratio controller for controlling that gaseous mixtures branched into the branch lines to have a specified pressure ratio by adjusting opening degrees of the valves based on measurement results obtained by using the pressure gauges. | 07-01-2010 |
| 20110220213 | DYNAMIC-ADAPTIVE VAPOR REDUCTION SYSTEM AND METHOD - A system and method for improved flow measurements for LCG, such as liquid petroleum gas (LPG), is disclosed. Embodiments of the present technology detect the presence of a vapor in a fluid flowing in a mass flow meter. A control valve is then adjusted to provide enough back pressure to prevent the measured liquid from flashing and to reduce the presence of vapor in the fluid flowing in the mass flow meter. By keeping the fluid in liquid form, the present technology reduces the vapor flowing in the mass flow meter, increasing the accuracy of mass flow and other measurements. Utilizing a similar principle of vapor detection, embodiments of the present technology provide for improved average parameter value calculation, such as average density calculations and equivalent liquid volume calculations. | 09-15-2011 |

| 20140116521 | SUBAQUEOUS MINING TAILINGS PLACEMENT - A process for reducing segregation of mining tailings while being deposited below the surface of a column of fluid is provided which comprises introducing the mining tailings into a downpipe having an inlet at or near the surface of the column of fluid and an outlet submerged in the column of fluid; providing at least one pressure drop element in the downpipe to prevent acceleration of the mining tailings and maintain the tailings flow therethrough; and providing a diffusing device at the outlet of the downpipe to reduce the velocity of the mining tailings as the tailings are discharged therefrom. | 05-01-2014 |
| 20140283917 | Vapor Delivery Device, Methods of Manufacture And Methods of Use Thereof - A method comprises transporting a first stream of a carrier gas to a delivery device that contains a solid precursor compound. The first stream of carrier gas is at a temperature greater than or equal to 20° C. The method further comprises transporting a second stream of the carrier gas to a point downstream of the delivery device. The first stream and the second stream are combined to form a third stream, such that the dewpoint of the vapor of the solid precursor compound in the third stream is lower than the ambient temperature. The flow direction of the first stream, the flow direction of the second stream and the flow direction of the third stream are unidirectional and are not opposed to each other. | 09-25-2014 |
| 20150047712 | Method and System for Blending Fluids - Methods and systems for real time, in situ monitoring and blending of hydrocarbon fluids from multiple transmission lines feeding into a downstream line or vessel are described. The method and system include the scanning of the NIR range on fluids within each of at least two transmission lines. The spectroscopic optical data from the two scans is used to determine flow rates of the fluids from each transmission line to, for example, achieve a desired energy content, physical properties, or speciation in the blended fluid. | 02-19-2015 |
