A2V were appointed to carry out the mechanical ventilation design for the new chlorine gas storage facility at Protea Chemicals. This included modifying the existing chlorine scrubber system so that it could serve the new storage facility as well as the existing facility.
The ventilation system was designed to ensure early detection of leaks with chlorine sensors situated at low points in the collection zone. The sensors activate the emergency extraction and scrubbing system and close the exits in the event of a tank rupture. The floor of the storage area is designed to be effectively ‘swept’ by even extraction via a low level extraction manifold located along one side of the facility.
A2V also carried out the Fire Prevention Plan for the new facility which was commissioned in September 2013.
