Abstract
A method may include: drawing a slip stream sample from a cooling fluid stream, the cooling fluid stream being fluidically coupled to an outlet of a heat exchanger and an inlet of a cooling tower; introducing the slip stream sample into an expansion chamber; and measuring a concentration of hydrogen gas within a headspace of the expansion chamber.
Claims20
A method comprising:
- drawing a slip stream sample from a cooling fluid stream, the cooling fluid stream being fluidically coupled to an outlet of a heat exchanger and an inlet of a cooling tower;
- introducing the slip stream sample into an expansion chamber;
- and
- measuring a concentration of hydrogen gas within a headspace of the expansion chamber.
1 more element
An apparatus comprising:
- a flow line fluidically coupled to an outlet of a heat exchanger;
- an expansion chamber fluidically coupled to the flow line;
- a gas detector disposed within the expansion chamber, the gas detector being operable to quantify a concentration of hydrogen within the expansion chamber;
- an alarm;
- and
- a control system operable to interpret a signal from the gas detector and activate the alarm when the signal exceeds a set point.
