Free chlorine is not – as it can be assumed – the chlorine gas (Cl 2), but the resulting products that are produced during the dissolving process of chlorine gas in water. First of all, it must be clear how the chlorine gas behaves during the dissolving process in the water. If chlorine gas is dissolved in water, hydrochloric acid and hypochlorous acid are produced
Amperometric measuring principle. Sensors for chlorine dioxide measurement feature a working electrode, which is separated from the medium by a thin membrane. Chlorine dioxide coming from the medium diffuses through this membrane and is reduced at the working electrode. The circuit is completed by means of the counter electrode and the

below pH3: Chlorine gas (Cl2) between pH3 and pH8: Hypochlorous acid (HClO) above pH8: Hypochlorite (ClO- ) In order to obtain a reliable free chlorine measurement you should either control or compensate the pH value of the measuring medium. Because the pH measurement is temperature dependent, it also makes sense to measure the temperature.

Recovering compression waste heat using latent thermal energy storage (LTES) is a promising method to enhance the round-trip efficiency of compressed air energy storage (CAES) systems.
Chlorine dioxide or free chlorine levels are determined according to the amperometric measuring principle. The chlorine dioxide (ClO 2) contained in the medium diffuses through the sensor membrane and is reduced to chloride ions (Cl-) at the working electrode. At the counter electrode, silver is oxidized to silver chloride.
In this chapter, fundamental considerations of energy conversion and storage devices are summarized to solve challenges related to the utilization of nonrenewable fossil fuel energy sources (coal, gas, and oil), such as increasing CO 2 emission because of human activities and global warming. Energy conversion and storage devices that can convert or store

The water stored in the tank provides the energy for process gas vaporization to continue even after the loss of the steam supply. This so-called “ballast” time is normally specified by the customer, especially for back-up systems. Typical ballast time is 3 to 5 minutes for this design. Ballast times up to 30 minutes are available, sometimes a requirement for high volume plant
