Convert Kilomoles per hour to Kilomoles per second
Convert Kilomoles per hour (kmol/h) to Kilomoles per second (kmol/s) instantly and accurately.
Conversion Formula
kmol/s = kmol/h × 0.0002777777778
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 Kilomoles per second
The kilomole per second (kmol/s) equals 1 000 mol/s, characterising the very largest industrial chemical processes. A world-scale ammonia synthesis plant produces ≈3 kmol/s of NH₃; a large steam methane reformer converts natural gas at ≈10 kmol/s. It is the preferred unit in European process simulation when outputs are in the thousands of tonnes per day. 1 kmol/s = 1 000 mol/s = 3 600 kmol/h.
