Mga Plant sa Paglilinis ng Gas

A Gas Cleaning Plant is a coordinated multi-stage system designed to purify industrial exhaust gases before they are released to the atmosphere. It typically combines dust removal, gas cooling, scrubbing, and sometimes chemical absorption to tackle pollutants such as particulate matter, acid gases (SO₂, HCl, HF), heavy metals, and volatile organic compounds. These systems ensure adherence to emission norms, protect downstream equipment, and lower environmental impact—similar to solutions adopted by leading global providers.

These plants often start with gas cooling—either via quench systems or heat exchangers—followed by primary dust removal using cyclones or multi-cyclones. Fine particulate removal may involve wet electrostatic precipitators or fabric filters. Gas-phase contaminants are handled via scrubbers, absorbent injection (like lime or activated carbon), or even advanced catalytic techniques such as SNOX or WSA. Designs may also include packed-bed absorbers for gaseous pollutants and mist eliminators to prevent liquid carryover.

Acid gases like SO₂ are typically neutralized using wet scrubbers (limestone/lime slurries), which convert them into gypsum or sulfates. Semi-dry or spray-dry techniques use powdered sorbents to avoid water, while systems based on catalytic processes (e.g., SNOX) oxidize and recover sulfur as high-purity sulfuric acid with no liquid waste or hazardous by‑products.
