摘要： A system for producing nitric acid at reduced power, the system being a standard dual pressure nitric acid plant further including features for splitting a tail gas stream into a first tail gas stream, in fluid communication with an oxygen-rich gas upstream the ammonia mixing unit, and a second tail gas stream, and features for adjusting the amount of tail gas being split into the first tail gas stream and the second tail gas stream, such that an air compressor is not required for operating the nitric acid plant. A method for operating the system, the use of the system for performing the method and, a method for revamping a standard dual pressure nitric acid plant into the system.

摘要： A device for reducing a carbon dioxide and water content in an enclosed air volume has first and second sorption units for sorbing carbon dioxide and water. The first and second sorption units can be transferred from a sorption mode into a desorption mode and vice versa. In the sorption mode, the first and second sorption units sorb carbon dioxide and water from raw air of the enclosed air volume. In the desorption mode, the first and second desorption units desorb carbon dioxide and water to supplied regeneration air. An air distribution device can switch the first and second sorption units, based on the carbon dioxide and water content, alternately from sorption mode into desorption mode such that, in at least one operating state of the device, one of the first and second sorption units is in sorption mode while the other is in desorption mode.

摘要： Methods of sequestering carbon dioxide (CO2) are provided. Aspects of the methods include contacting a CO2 containing gaseous stream with an aqueous medium under conditions sufficient to produce a bicarbonate rich product. The resultant bicarbonate rich product (or a component thereof) is then combined with a cation source under conditions sufficient to produce a solid carbonate composition and product CO2 gas, followed by injection of the product CO2 gas into a subsurface geological location to sequester CO2. Also provided are systems configured for carrying out the methods.

摘要： A system includes a catalyst for receiving and treating exhaust gas generated by an engine, a passive NOx adsorber (PNA) positioned upstream of the catalyst, a bypass valve positioned upstream of the catalyst and the PNA, and a controller. The controller is configured to: while controlling the bypass valve to direct exhaust gas to the PNA, detect a torque demand that is greater than a threshold value; responsive to detecting that the torque demand is greater than the threshold value, engage a motor, coupled with a battery system, with a drive shaft of the system to meet at least a portion of the torque demand; in response to the engagement of the motor with the drive shaft not meeting all of the torque demand, engage the engine with the drive shaft to meet a remainder of the torque demand.

摘要： The application provides articles, systems, and methods for adsorbing and desorbing nitrogen oxides (NOx) at desired temperatures. The catalytic article comprises a NOx adsorber composition comprising a platinum group metal (PGM) component disposed on or impregnated in a support material, and a substrate, wherein the catalytic article further comprises a magnetic material capable of inductive heating in response to an applied alternating electromagnetic field. The catalytic article further comprises a conductor associated therewith for receiving current and generating an alternating electromagnetic field in response thereto, wherein the conductor is positioned such that the generated alternating electromagnetic field is applied to at least a portion of the magnetic material. This field can inductively heat the magnetic material to heat the NOx adsorber composition to desorb the NOx from the NOx adsorber composition.
