What Do Scrubbers Do in Smoke Stacks? Sciencing

The resulting chemical reaction produces a synthetic form of the mineral gypsum, which can be adapted for use in concrete or drywall. This can be done in a few different ways. In a "wet scrubber," the untreated exhaust is sent through a spray chamber where fine water droplets knock down the harmful particulates.

Sulfur Dioxide Scrubber: pH Control Yokogawa China Co., Ltd.

Power plant boiler houses designed to burn coal or high sulfur oil are required by Federal and State pollution regulations to "scrub" (remove) sulfur dioxide from flue gasses to meet emission limits. SO 2 in flue gasses is known to be harmful to the environment, as it is one contributor to the formation of acid rain. pH control is critical for the proper functioning of the scrubber system.
