Convert Pound-moles per hour to Moles per second
Convert Pound-moles per hour (lb-mol/h) to Moles per second (mol/s) instantly and accurately.
Conversion Formula
mol/s = lb-mol/h × 0.1259978806
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 Moles per second
The mole per second (mol/s) is the SI coherent derived unit of molar flow rate, numerically equal to the katal (kat) for catalytic activity contexts. Industrial ammonia synthesis (Haber-Bosch) produces ≈50 mol/s of NH₃ per tonne/h output; a large turbine combustion chamber burns natural gas at ≈500 mol/s of CH₄. It is the reference unit in process simulation mass balances. 1 mol/s = 3 600 mol/h = 60 mol/min.
