Abstract: A precision volumetric liquid dispensing instrument is disclosed that includes two pressure sensors and a fluid passageway with a defined volume portion in communication with the two sensors for receiving and distributing liquid in relatively small volumes. One of the pressure sensors is positioned to measure pressure at one portion of the defined volume portion of the fluid passageway and the other of the gas pressure sensors is positioned to measure gas pressure at a different portion of the defined volume portion of the passageway. At least one valve is in communication with the passageway for moving fluids into or out of the defined volume portion of the fluid passageway, and a processor carries out a step selected from the group consisting of (i) calculating the volume of the liquid based upon the measured pressure and (ii) metering a liquid into the defined volume portion of the fluid passageway until the measured pressure indicates that a desired volume of fluid is in the fluid passageway.

Abstract: A system for vaporizing and optionally decomposing a reagent, such as aqueous ammonia or urea, which is useful for NOx reduction, includes a cyclonic decomposition duct, wherein the duct at its inlet end is connected to an air inlet port and a reagent injection lance. The air inlet port is in a tangential orientation to the central axis of the duct. The system further includes a metering valve for controlling the reagent injection rate. A method for vaporizing and optionally decomposing a reagent includes providing a cyclonic decomposition duct which is connected to an air inlet port and an injection lance, introducing hot gas through the air inlet port in a tangential orientation to the central axis of the duct, injecting the reagent axially through the injection lance into the duct; and adjusting the reagent injection rate through a metering valve.
