Amanonin synthesis is a gas phase resction betwren nitrogen amd hydrogen at ca 350 C atad at a presere of ca 180 bar. N2+3H2=2NH3 Becanse there is not cospplete conversion in the reactor, it Es necesary to recycle ancoalverted gev after atmmonia is knocked out. The raakenp stean (stream 0) consists of 1 ul\% argoat (inest) that reabahn in gas phase. Therefore, it in necesesy to purge sotae of the gas in order to beop the inert concentration at a renoodable level. In this context we only look at the molar flosy, therefore the flowsloee does not show that strean 2 is cooled to a temperature where amanonii is condetsed and ofrenm 4 is recompressed. The flow rate of the makesp stream ts 1000kmol/h with a cotmponition of 24mol% nitrogen, 75 molX hydrogen and 1 molWe argot. In the separator all argon ends up in the gas phase (over top), and all annonia cads ap in the ligaid phase. Furthermore, we awume 99% of all hydrogen and 98% of all nitrogen goes oker top (on a molar basis). Assume a split Alow ratio of 95%, i.e. 5% of stream 3 gors to jarge, It the renctor we avaame that 30% of all nitrogen in streatu 1 is converted to ammonia. 1 TKP4165 - Spring 2023 M. Hillontad Dving 3 Dept. of Cheraical Enginevering, a) Formulate nol balances for each urit. b) Calculate molar flow tates for all conposents and all streasas and colculate the stream compositions. e) Verify that the conservation of mass is fulfilied. d) Change the split flow ratio in the range frotn 0.100 to 0.93 and plot the inert concentration of strean 1, recycle ratio and the total parge as function of the split ratio
