Investigation of Chlorine Gas Emission Hazards at ABFA Chlorination Plant at Abadan Station using Aloha and Marplot Software

Case Study (دارای رتبه معتبر)

Chlorine is a toxic and oxidizing gas used in Iran to purify drinking water, and failure to control the effects of a gas leak or tank explosion could cause irreparable harm to workers and residents around the station. There has been no research on this issue in the city of Abadan. This research investigated the release of chlorine gas from a 1000-liter tank at 1 tonne and 1.5 tonnes at the Abadan Chlorination Station. Aloha software was used to investigate the rate of diffusion, different risk areas, and the population at risk. The investigations show that the release of gas in the event of damage to the one-inch outlet valve of the tank can be lethal up to a radius of 2 km, effective up to a radius of 6.2 km, and felt up to 10 km. Considering the possibility of an accident and the location of the station in the direction of the wind, it is possible to harm a large number of citizens living within a 5 km radius of the station. Effective measures are therefore needed to inform the local population, raise awareness among employees and emergency services, install a suitable scrubber, and increase the safety level of the station.
