Scrubber System

A scrubber system is an industrial device designed to remove pollutants, contaminants, and particulate matter from gases, air, or other exhaust streams. Scrubber systems are commonly used in industries such as chemical processing, oil & gas, power generation, and manufacturing to reduce the environmental impact of emissions and meet regulatory compliance.

These systems use a liquid (often water or a chemical solution) to capture pollutants from gases. The gas is passed through a scrubbing liquid, which absorbs or neutralizes the contaminants.

Packed Bed Scrubbers: Utilize a packed bed of material for gas-liquid contact to remove pollutants.

Venturi Scrubbers: Employ high-velocity gas flow through a nozzle to create a mist of liquid, which then captures the pollutants.

Spray Tower Scrubbers: Involve spraying the contaminated gas with liquid inside a tower to remove contaminants.

Dry scrubbers use solid adsorbents or dry reagents to remove pollutants from gas streams. They are typically used when wet scrubbing is not feasible or if water conservation is important.

Lime/Alkali Scrubbers: Use dry lime or alkaline reagents to neutralize acid gases like sulfur dioxide (SO2) and hydrochloric acid (HCl).

Adsorptive Scrubbers: Use activated carbon or other adsorbents to trap volatile organic compounds (VOCs) and other gases.

A combination of wet and dry scrubbers, these systems can handle both particulate matter and gaseous pollutants. They often incorporate features from both types to offer enhanced flexibility and effectiveness.
