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.

About Millimoles per second

The millimole per second (mmol/s) equals 10⁻³ mol/s, used in mid-scale continuous-flow chemistry and laboratory reactor design. A syringe pump delivering 10 mL/min of a 6 mmol/L reagent solution delivers 1 mmol/s to the reactor; 1 mmol/s is also the millicatalytic unit (mkat) used as an aggregate activity measure in industrial bioprocess monitoring. 1 mmol/s = 10⁻³ mol/s = 3.6 mol/h.
