we have 2000MT/day ammonia production rate , 21 days shut down per year . annual ammonia production rate = 2000MT/day *344day/year =688.000MT/year . which is equivalent a mole flow rate of : 688.000MT/year * 1000kg/MT* 1/17.0306 kmol/kg *1/344year/day *1/24 day/hr=4893.1531 kmol/hr . if natural gas composition as the following : methan 94.4%mol feed , ethane 0.80mol%, propane 0.03 mol% , nitrogen 4.24mol% , hydrogen 0.00, argon 0.00 , oxygen0.00 water 0.00 , carbondioxide 0.44mol%, carbonmonoxide 0.00 , and ammonia 0.00 . product composition for ammonia 99.99mol% .calculate Autothermal reforming material balance for all the plant (manual and summary tabels) . please use Auto-thermal reforming technology .
