Dry sorbent injection may serve as a key pollution control technology at power plants
Dry sorbent injection (DSI) is a pollution control technology that may play a role in the United States' electric power sector's compliance with the Mercury and Air Toxics Standards (MATS). The Environmental Protection Agency (EPA) finalized the MATS rule in December 2011. The MATS rule requires that all U.S. coal- and oil-fired power plants greater than 25 megawatts meet emission limits consistent with the average performance of the top 12% of existing units— known as the maximum achievable control technology (MACT).
