Sealed Air

Atlas Copco's oil-free compressors deliver ISO 8573 Class 0 air for pharmaceutical and food-grade nitrogen production. PSA nitrogen generators — our zeolite beds separate N2 from O2 on demand. Purity controlled by molecular sieving.

Topsoe's ammonia synthesis catalysts (iron-based KM series) have produced fertilizer feeding billions since the 1940s. Our latest SK-501 methanol synthesis catalyst operates at lower temperature, higher per-pass conversion. Catalyst = chemistry's multiplier.

Froth flotation chemistry separates copper ore from gangue — xanthate collectors selectively bind to sulfide minerals, attaching them to air bubbles. Without these molecules, battery-grade copper stays in the rock.
