About Pound-moles per hour

The pound-mole per hour (lb-mol/h) equals 453.59237/3600 ≈ 0.12600 mol/s, the standard molar flow unit in US chemical process engineering simulation (Aspen Plus, HYSYS, Pro/II). Distillation column feed rates, reactor effluent streams, and compressor suction flows are universally expressed in lb-mol/h in US petrochemical and refinery design. 1 lb-mol/h = 453.59237/3600 mol/s ≈ 0.12600 mol/s ≈ 0.4536 kmol/h.

About Megamoles per hour

The megamole per hour (Mmol/h) equals 10⁶/3600 ≈ 277.78 mol/s, used for atmospheric chemistry flux estimates and mega-scale industrial chemical throughput. Global annual CO₂ emissions of ≈37 Gt/year correspond to ≈24 Mmol/h; the global ammonia industry produces ≈190 million tonnes/year of NH₃, equivalent to ≈62 Mmol/h. 1 Mmol/h = 10⁶/3600 mol/s ≈ 277.78 mol/s.
