Citizens Gas and Coke Utility in Indianapolis, Indiana, which operates as the public Department of Utilities
for the City, completed the construction of a $35 million ammonia destruct/desulfurization facility. The
ammonia destruct facility, the first phase of the project, pleted in 1990 and has eliminated more
than 5000 pounds of ammonia per day that previously was discharged into the city's wastewater treatment
plants. The ammonia destruct system is over 90% efficient. The ammonia molecule is destroyed at high
temperature using nickel catalyst, and even the resulting hydrogen gas is used as an energy source for the
Citizens Gas and Coke Utility coke oven batteries.
The second-phase of the project, the desulfurization plant, pleted in 1994. The plant eliminates
over 4000 tons of hazardous waste each year. % pure elemental sulfur is recovered for sale. Shown
above is the sulfur recovery section of the plant.
The ammonia destruct facility was the first of its kind in the Western Hemisphere, and coupled with its
sister desulfurization facility, represents the bination ammonia destruct/desulfurization facility
like it in the world. (Photo Courtesy of Citizens Gas and Coke Utility.)
