Dry Sorbent Injection - Performance and Costs

Report summary

Dry Sorbent Injection (DSI) is an acid gas removal system available for compliance with various environmental regulations. It involves the injection of a dry material directly into the flue gas stream of a coal-fired electric generating unit (EGU). Common dry sorbents used in DSI systems are normally sodium-based trona, soda ash (sodium carbonate), or calcium-based lime. These materials are widely used in various industries across the United States. EGU owners and operators have expressed...
