Fluorometric control of aromatic oxygen sca vengers in a boiler system

摘要

The invention provides a method of enhancing the fluorescent signal of a fluorescent oxygen scavenger compound comprising:
a) providing a stream comprising a fluorescent oxygen scavenger compound selected from the group consisting of compounds with two or three adjacent hydroxyl groups on an aromatic ring;
b) providing one fluorometer;
c) adding borate to said stream; and
d) using said fluorometer to detect the fluorescent signal of said fluorescent oxygen scavenger in said stream.
The fluorescent oxygen scavenger is most preferably Gallic Acid. The method of the invention allows for more accurate control of the addition of Fresh Oxygen Scavenger Product to a Boiler System.
