The Hydra-Vent absorption column absorbs any minor releases of chlorine gas from a pressure relief device. All vacuum regulators/chlorine gas systems include a safety vent facility to relieve gas if the system pressure rises above atmospheric. These releases may occur due to a minor fault or routine operations.
By terminating vent lines to the Hydra-Vent absorption column any atmospheric release of chlorine gas in standard chlorine systems will be alleviated under normal operating conditions for up to 12 months.
The absorption capacity of the Hydra-Vent is 0.6kg of chlorine gas.
Australian Standard AS 2927 compliance
Installing a Hydra-Vent where the relief terminal point is located indoors, meets the requirements of AS 2927:2019 for the storage and handling of liquefied chlorine gas. It will minimise the exposure of personnel and equipment to minor nuisance releases.
Absorption media should be replaced at twelve monthly intervals, or alternatively if an alarm indicates that saturation has occurred.
Regularly changing the absorbent maintains their effectiveness and ensures compliance with Australian Standard AS 2927:2019
- Improved safety by optimum location of vent line termination
- Reduced surface corrosion in the vicinity of vent termination
- Can be installed in the chlorine room providing the most secure termination point
- A chlorine leak detector sensor located adjacent to the absorption column will provide an alarm in the event of media saturation
