State Metal Industries - Executive Summary

Two chlorine evaporation systems are fed liquid chlorine from 2000 pound cylinders and each system feeds gaseous chlorine to an aluminum furnace.  The gaseous chlorine is injected into a molten aluminum pump and reacts with magnesium impurity to refine the aluminum.  The Chlorine Building can house up to 8 one-ton chlorine cylinders at a time.  In case of a chlorine leak the building can be manually vented to the plant air pollution control system for dilution, some neutralization with ammonia, and dispersal from a stack. The first system has operated safely for over 10 years and the second system over 4 years.  Both systems have operated without any  offsite consequences.  The facility has an emergency response team on site and drills regularly.
