  2. Liquid nitrogen wash - Wikipedia

    en.wikipedia.org/wiki/Liquid_nitrogen_wash

    The liquid nitrogen wash has two principle functions: [1] Removal of impurities such as carbon monoxide, argon and methane from the crude hydrogen gas; Addition of the required stoichiometric amount of nitrogen to the hydrogen stream to achieve the correct ammonia synthesis gas ratio of hydrogen to nitrogen of 3 : 1

  3. Kipp's apparatus - Wikipedia

    en.wikipedia.org/wiki/Kipp's_apparatus

    Basic gases (e.g. ammonia) can be dried with calcium oxide, sodium hydroxide or soda lime. Disposal of the gases can be done by burning the flammable ones (carbon monoxide, hydrogen, hydrocarbons), absorbing them in water (ammonia, hydrogen sulfide, sulfur dioxide, chlorine), or reacting them with a suitable reagent.

  5. Hand pump - Wikipedia

    en.wikipedia.org/wiki/Hand_pump

    Where it is necessary to raise water to a height above that to which a suction or lift pump will operate effectively (about 7 metres), or to raise the pressure so that it will exit a nozzle with a strong force, such as through a fire hose, a force pump may be used. As with a suction pump, in its manual form it relies on an operator to pump a ...

  6. Diesel exhaust fluid - Wikipedia

    en.wikipedia.org/wiki/Diesel_exhaust_fluid

    When it is injected into the hot exhaust gas stream, the water evaporates and the urea thermally decomposes [13] to form ammonia (NH 3) and isocyanic acid (HNCO): (NH 2) 2 CO → NH 3 + HNCO. The isocyanic acid reacts with the water vapor and hydrolyses to carbon dioxide and ammonia: HNCO + H 2 O → CO 2 + NH 3. Overall, thus far: (NH 2) 2 CO ...

    The ammonia extracts the fluid and destroys eye cells and tissue in minutes. 6. Draining of ammonia into sea while pre-cooling of the hard-arm or during disconnection operations is not an eco-friendly operation. As a small quantity of ammonia as low as 0.45 mg/L (1.6 × 10 −8 lb/cu in)(LC50) is hazardous to Salmon as per ICSC, USA ...

  8. Recirculating aquaculture system - Wikipedia

    en.wikipedia.org/wiki/Recirculating_aquaculture...

    Water is pumped through the filter, and ammonia is utilized by the bacteria for energy. In recirculating systems, daily water exchanges are commonly used to control nitrogen levels. Stable environmental conditions and regular maintenance are required to ensure the biofilter is operating efficiently. [citation needed]

  9. Maser - Wikipedia

    The first prototype ammonia maser in front of its inventor Charles H. Townes. The ammonia nozzle is at left in the box, the four brass rods at center are the quadrupole state selector, and the resonant cavity is at right. The 24 GHz microwaves exit through the vertical waveguide Townes is adjusting. At bottom are the vacuum pumps.
