Conversion Formula
Mmol/d = lb-mol/h × 0.01088621688
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 day
The megamole per day (Mmol/d) equals 10⁶/86400 ≈ 11.574 mol/s, encountered in global biogeochemical cycle research and the largest industrial chemical operations. Ocean-atmosphere CO₂ exchange is estimated at 600-900 Mmol/d; terrestrial gross primary production consumes approximately 700 Mmol/d of CO₂; continental-scale methane budgets use the same unit. 1 Mmol/d ≈ 11.574 mol/s ≈ 41.67 kmol/h.
