Nenvitech nh3 process for gas measurement

Nenvitech nh3 process for gas measurement

The CO in the process gas from the secondary reforming step (representing approximately 15 percent of the process gas) is converted to CO2 in the presence of a catalyst, water, and air in the shift conversion step. CO2 is removed from the process gas by the shift conversion process, and the hydrogen is combined with the nitrogen (N2)

  • Measurement of NH3 Concentrations in Stack Flue Gas Using

    Process Overview. The NH 3 gas is injected to remove the NOx and thus reduce the NOx concentration in the stack flue gas, as well as to increase the dust collection efficiency of the dust collector (ESP) and prevent erosion. Excess NH 3 injection increases the running cost and the residual NH 3 amount, resulting in the generation of a foul odor. Therefore, the NH 3 concentration in the stack flue gas is measured, controlled, and monitored.

  • Ammonia - Wikipedia

    Ammoniacal nitrogen (NH 3-N) is a measure commonly used for testing the quantity of ammonium ions, derived naturally from ammonia, and returned to ammonia via organic processes, in water or waste liquids. It is a measure used mainly for quantifying values in waste treatment and water purification systems, as well as a measure of the health of natural and man-made water reserves.
