Distillation Vacuum Stage Requirements Vacuum distillation systems separate heat-sensitive compounds, high-boiling petroleum fractions, pharmaceuticals, and essential oils by lowering operating pressure. Reducing pressure lowers boiling points dramatically—water boils at 100 °C at atmosphere but at only 46 °C at 50 Torr—preventing thermal decomposition while improving separation efficiency. Most industrial and laboratory vacuum distillation processes operate

Required Vacuum Level for Aerospace Coating Aerospace component manufacturing demands ultra-clean deposition environments for protective coatings on turbine blades, landing gear, satellite structures, and avionics hardware. Physical vapor deposition (PVD) processes—including electron-beam PVD for thermal barrier coatings (TBCs) and magnetron sputtering for wear-resistant layers—require base pressures typically between 10⁻⁵ and 10⁻⁷ Torr (1.33 × 10⁻³
