About
An exhaust scrubber is an air pollution control device that removes harmful pollutants, such as sulfur oxides (

SOxcap S cap O sub x
) and particulate matter, from exhaust gases. It works by spraying a liquid, like seawater or an alkaline solution, onto the exhaust stream to trap contaminants, which then cleans the air before it's released into the atmosphere. These systems are commonly installed on ships to comply with emissions regulations
