Pound-moles per hour (lb-mol/h)
Kilomoles per hour (kmol/h)

Conversion Formula

kmol/h = lb-mol/h × 0.45359237

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 Kilomoles per hour

The kilomole per hour (kmol/h) equals 1000/3600 ≈ 0.27778 mol/s, the dominant molar flow unit in European and international process engineering. Equipment datasheets for distillation columns, heat exchangers, compressors, and chemical reactors all specify flows in kmol/h. A 500 MW gas turbine power plant burns natural gas at ≈50-80 kmol/h. 1 kmol/h ≈ 0.27778 mol/s ≈ 2.205 lb-mol/h.
