摘要： A flue gas desulfurization process and system that utilize ammonia as a reactant, and in which any hydrogen sulfide and/or mercaptans within the ammonia are separated during the desulfurization process so as to prevent their release into the atmosphere. The process and system entail absorbing acidic gases from a flue gas with a scrubbing media containing ammonium sulfate to produce a stream of scrubbed flue gas, collecting the scrubbing media containing the absorbed acidic gases, injecting into the collected scrubbing media a source of ammonia that is laden with hydrogen sulfide and/or mercaptans so that the injected ammonia is absorbed into and reacted with the collected scrubbing media, stripping the hydrogen sulfide and/or mercaptans from the collected scrubbing media by causing the hydrogen sulfide and/or mercaptans to exit the collected scrubbing media as stripped gases, and collecting the stripped gases without allowing the stripped gases to enter the stream of scrubbed flue gas.

摘要： The adaptive system and method for ultrasound sensing comprises re-evaluating over time the detection threshold for predetermined sensing positions along the scanning direction to cope for the static target and environment changes at the sensing positions. The method includes comparing the measured echo value at each sensing position to a reference echo value corresponding to the same sensing position, and to iteratively determine a new reference value whenever the echo value is greater than the reference echo value and that the difference between the measured echo value and the reference echo value is lower than a detection assurance factor. The use of the adaptive ultrasound sensing system and method allows locating the sensor at different location without requiring a new calibration thereof, since the sensor learns the clutter dynamically and the detection thresholds are being built accordingly without being dependent on the environment in which the sensor is located.

摘要： A digital input device for entering data into a digital system, comprises at least two remote sensors and a control unit. A working area is set up in proximity to the sensors and the position of an object within the working area is detected by the input device based on data provided by each sensor and transmitted, by said control unit, to said digital system. The position of an object outside said working area, if detected by said input device, is rejected by said control unit and is not transmitted to said digital system. The sensors can be ultrasonic sensors and the object can be a part of the body of a user. Use of a third sensor allows three-dimensional detection of the object.

摘要： Process for the removal of sulfur oxides from sulfur oxide-containing gas with simultaneous production of ammonium sulfate. The process is carried out by first passing hot sulfur oxide-containing gas through a prescrubber wherein the gas contacts saturated aqueous ammonium sulfate liquor which is recycled in the prescrubber, followed by passing the prescrubbed gas through an absorber wherein the prescrubbed gas contacts dilute aqueous ammonium sulfate liquor. The sulfur oxide in the sulfur oxide-containing gas is absorbed by the dilute aqueous ammonium sulfate liquor in the absorber, and scrubbed gas is removed from the absorber. The dilute aqueous ammonium sulfate liquor is treated with ammonia and air and the absorbed sulfur dioxide is converted to ammonium sulfate in the liquor. The dilute ammonium sulfate liquor is recycled into contact with the prescrubbed gas in the absorber. Dilute aqueous ammonium sulfate liquor is removed from the absorber and added to the saturated aqueous ammonium sulfate liquor in the prescrubber where it becomes saturated due to evaporation caused by the hot gas. Ammonium sulfate crystals form in the saturated aqueous ammonium sulfate liquor in the prescrubber are recovered as product from saturated aqueous ammonium sulfate withdrawn from the prescrubber.

摘要： A method and system for removing hydrogen sulfide from a hot gas. In a moving bed absorber, sulfur compounds in the hot gas moving in a direction which is countercurrent to the direction of movement of the movable bed of metal oxide, react with metal oxide to form metal sulfide. The metal sulfide is regenerated to re-usable metal oxide in a moving bed regenerator. The regeneration is carried out with an oxygen-containing gas in which regenerator off-gas serves as a diluent to control oxygen concentration. In the regenerator, spent metal sulfide moves progressively through a single regeneration vessel having first, second and third regeneration stages. In the first and second regeneration stages, first and second oxygen and sulfur dioxide-containing gases move, respectively, in a direction which is cocurrent with the direction of movement of a movable bed of spent metal sulfide. In the third regeneration stage, an oxygen-containing gas moves in a direction which is countercurrent to the direction of movement of the movable bed of metal sulfide from the second regeneration stage. The combined gases derived from the first, second and third regeneration stages and which are rich in sulfur dioxide and lean in oxygen, are removed from the regenerator as off-gas and used as diluent with air, oxygen-enriched air or pure oxygen to provide the low oxygen concentration in the oxygen-containing gas introduced into the first and second regeneration stages.

摘要： A system and method for short-range ultrasonic detecting of a target is proposed herein to be used for example in a liquid-dispensing system such as those provided in home refrigerators. The system comprises a sensor assembly including a transmitter and a receiver positioned side by side so as to yield respective transmitting and receiving beams which overlap to define an asymmetrical shaped detection area, a controller coupled to both the transmitter and receiver to activate the transmitter and for receiving echoes indicative of the target from the receiver and to the dispensing system for opening a valve of the dispensing system when a target is detected. Noises and false alarm rate minimization methods are implemented, including variable relevance zones and requiring a void of signal before excitation.

摘要： A method and system for CO2 capture from flue gas uses an absorber vessel in which a flue gas stream containing CO2 is contacted with an ammoniated solution to remove CO2 from the flue gas, and a regenerator vessel in which CO2 is released from the ammoniated solution. Parasitic energy consumption of the system can be reduced by adding to the ammoniated solution a promoter effective to enhance the formation of ammonium bicarbonate within the ammoniated solution. The amount of ammoniated solution recycled from the regenerator vessel to the absorber vessel is less than that which would be required using the ammoniated solution without the promoter for removal of the same amount of CO2 from the flue gas.
