Pollution by so2 serves as a key problem in sulphuric acid plants. We have put up giant absorbers for so2 in such plants. The specialty of our system is that whereas naoh is tailored to facilitate the uptake of so2, This item is nahso3 and not na2so3. Thus the consumption of naoh is reduced to 50%. A ph control system automatically recharges and refreshes the scrubbing liquid when it is exhausted. A two, Stage countercurrent cascade is utilized for the effective extraction of harmful gases to manage pollution levels standards. Sodium metabisulphite is a valuable bye, Product in this scheme. We operate as a trusted fabricator and provider containing sulfur dioxide absorber.
