Dry scrubbing is a pollution control technology used to remove harmful gases and particulates from industrial emissions. It typically involves passing exhaust gases through a solid sorbent material, which captures pollutants without the need for water. This method is effective for reducing sulfur dioxide, nitrogen oxides, and other harmful substances in the air. The process is often employed in power plants and manufacturing facilities to meet environmental regulations. By using dry scrubbing systems, industries can minimize their environmental impact while maintaining compliance with laws designed to protect air quality and public health.
