What device is used to remove poisonous gases from industrial emissions before they are released into the atmosphere?

The device used to remove poisonous gases from industrial emissions is called a scrubber. Scrubbers work by spraying a liquid solution that captures harmful pollutants, such as sulfur dioxide and particulates, from the gas stream. The cleaned gas is then released into the atmosphere, significantly reducing environmental impact. There are various types of scrubbers, including wet and dry scrubbers, each suited for specific applications.
