  • Automate the Mixing of Anhydrous Ammonia and Water
  • Ammonia Stripping Explained
    upward through the. packing. Since the ammonia is partially. present as a dissolved gas, some of the. ammonia transfers from the water to the. air.
  • EPA Increases Ammonia Emissions Control
    Concern about ammonia emissions in the air and the water continues to grow, both officially and unofficially. As U.S. Environmental Protection Agency (EPA) moves to further reduce ammonia concentrations in surface waters, common water treatment methods transform what had been a water pollution
  • Efficient Ammonia Removal Using Modular Liqui-Cel (R) Contactors (.pdf)
    the ammonia so that it is not discharged back into the environment. There are many conventional ways to remove ammonia from water but most of them produce a secondary waste stream that can cause a whole list of other problems. Membrane Contactors offer a superior solution for stripping Ammonia
  • A Review of Solid Materials as Alternative Ammonia Sources for Lean NOx Reduction with SCR (.pdf)
    (32.5 wt %) dissolved in water or Diesel Exhaust Fluid (DEF) as the ammonia source. While DEF or AdBlue (R) is widely used as a source of ammonia, it has a number of issues at low temperatures, including freezing below -12 oC, solid deposit formation in the exhaust, and difficulties in dosing
  • MICRO: Critical Materials
    posed by moisture in ammonia has driven the development of continuous-detection instrumentation. Because ammonia and water are chemically similar, spectroscopic methods have proven to be the most promising option for detecting trace moisture in ammonia down to parts-per-billion levels. Since
  • How does SCR work
    elemental nitrogen and water. The two common sources of neutralizing chemical are either ammonia, which is a gas at room temperature or urea, which is normally used as a solution and must be atomized into the air.
  • pH Calculation by Differential Conductivity Measurement in Mixtures of Alkalization Agents
    Proper measurement of pH is a key factor in corrosion risk surveillance in water-steam cycles. Since it still seems difficult to measure the sample pH directly with glass electrodes, pH calculation, using the difference between sample conductivity before and after a strong acid ion exchanger
