Abstract
A quencher for a flow cell battery is described. The quencher utilizes a quench solution formed from FeCl2 in a dilute HCl solution in order to quench chlorine emissions from the flow cell battery. A quench sensor is further described. The quench sensor monitors the concentration level of FeCl2 in the quench solution and may also monitor the level of the quench solution in the quencher.
Claims16
A quench system, comprising:
- a quench solution including FeCl2 in a dilute HCl solution;
- a container holding the quench solution, the container including an input that directs a gaseous emission into the quench solution;
- and
- a quench sensor including:
- a double walled tubing having an open-ended inner volume and a sealed outer volume,
- a first light source and a corresponding first detector, and
- a second light source and a corresponding second detector, wherein:
- the quench sensor is positioned in the container such that before any quenching has begun, the first light source and the corresponding first detector are positioned in the sealed outer volume below a quench solution level, and the second light source and the corresponding second detector are positioned in the sealed outer volume and at a predetermined threshold level above the quench solution level, and
- Cl2 gas is removed from the gaseous emission by a reaction with the quench solution.
