The scrubber tower is a core industrial equipment that utilizes gas-liquid contact mass transfer principles to purify, separate, or absorb gases. By counter-currently contacting the target gas with a scrubbing solution (e.g., water or solvents), it removes particulates and harmful components (e.g., SO₂, NOₓ, VOCs) while recovering valuable substances. Widely applied in environmental remediation, chemical separation, and energy sectors, this technology demonstrates significant industrial value.
