Trona + Oil Shale Soda Ash HEAT The older technology, used in Wyoming today, simply heats trona and oil shale to convert the trona into soda ash (Na 2 Co 3 )

Trona + Oil Shale Soda Ash HEAT This “dirty” process also cooks millions of tons of oil shale each year, boiling the oil shale products into the atmosphere.... HAPs + CO 2 + H 2 O Poisonous Benzene Cloud

Trona + Oil Shale Soda Ash HEAT..oil shale particulate products are also released.... HAPs + CO 2 + H 2 O Poisonous Benzene Cloud

HEAT Trona + Oil Shale Soda Ash + Liquid / Solid Waste Limestone (CaCO 3 ) CaO CaCO 3 Newer technologies, use less energy to heat limestone (CaC0 3 ), which is used over-and-over again, to chemically convert trona into soda ash…

HEAT Trona + Oil Shale Soda Ash + Liquid / Solid Waste Limestone (CaCO 3 ) CaO CaCO 3 Newer technologies do not heat oil shale, use less energy, and release less CO 2 ……a greenhouse gas… CO 2 Non-Poisonous Greenhouse Gas

HEAT Trona + Oil Shale HAPs + CO 2 + H 2 O Soda Ash Trona + Oil Shale Soda Ash + Liquid / Solid Waste HEAT Limestone (CaCO 3 ) CaO CaCO 3 CO 2 Non-Poisonous Greenhouse Gas Poisonous Benzene Cloud Wyoming’s Process Green Process
