Sweetwater County Soda Ash Plants Process Wyoming Trona Into Soda Ash. “Left Click” to Next Slide

Sweetwater County Soda Ash Plants Process Wyoming Trona Into Soda Ash. Approximately 13 Million tons of Soda Ash are Produced Each Year by 4 Producers. “Left Click” to Next Slide

Soda Ash Producers burn Thousands of Tons of Coal Each Day to Convert Trona into Soda Ash. “Left Click” to Next Slide

The Soda Ash Producers also Calcine, or Heat, Thousands of Tons of Oil Shale Each Year Releasing Hazardous Air Pollutants (HAPS). “Left Click” to Next Slide

Soda ash production facilities heat Trona-oil shale to several hundred degrees. At these temperatures, water boils and is released as a vapor. Hot Gases at 350 - 400F 25 million tons / year Soda Ash Plants Trona-Oil Shale “Left Click” to Next Slide

Trona Cloud of Condensing Vapors As the hot vapors contact colder air, the vapors condense…like a car's exhaust on a cold day… Colder Air Trona Cloud of Condensing Vapors Hot Gases at 350 - 400F 25 million tons / year Soda Ash Plants Trona-Oil Shale “Left Click” to Next Slide
