Hydrazine analyzer HYDRLYT LP 100

The analyzer is used in power plants to determine the residue hydrazine concentration in boiler feed-water with system pressure of higher than 62 bar and alkali operation. The task of the hydrazine in the water loop is to eliminate the existing oxygen content and simultaneously arise the pH-value. The  deoxygenated process can describe according following equation:

                                       N₂H₄ + O₂ => N₂ + 2 H₂O

Because hydrazine is carcinogen the use should be cautious. Thus the hydrazine concentration in the water circuit have to be measured.

The electrochemical electrode reaction may be represented qualitatively as:

N₂H₅OH + 4 OH^- => N₂ + 5 H₂O + 4 e^-
