 Light ceramic structured packings is widely used as the chemical packing of desulfurizing, washing, debenzolization, naphthalene-cleaning, rectification, absorption, drying tower in chemical-processing coal and fine chemicals industryies, such as petroleum, coking, generating, fertilizer, synthetic ammonia. And it is allso used as cooling packing in watering tower.
