Sunflower oil contains 0.070 mol palmitic acid (C16H32O2)/mol,0.060 mol stearic acid (C18H36O2)/mol, 0.37mol oleic acid (C18H34O2)/mol, and 0.50mol linoleic acid (C18H32O2)/mol. To create margarine from sunflower oil, the liquid oleic and linoleic acids are hydrogenated in the presence of a metal catalyst to form solid stearic acid. C18H34O2+H2C18H36O2C18H32O2+2H2C18H36O2 At a margarine production facility, a stream of 485.0mol sunflower oil/h is fed into a reactor. The fresh hydrogen source available is a mixture containing 0.95molH/mol and 0.050molN2/mol. N2 is inert in this process. To ensure complete hydrogenation, the hydrogen gas mixture is introduced into the reactor in 65.0% excess. All reaction products leave the reactor and proceed to a separator where palmitic and stearic acids are separated from the hydrogen gas mixture. The hydrogen gas mixture is recycled to the fresh feed stream, and 115.0mol gas /h of this recycle stream is purged to prevent the buildup of nitrogen gas, What is the molar flow rate of the fresh hydrogen and nitrogen gas mixture to the process? flow rate: molgas/h What is the composition of the purge stream? mole fraction of hydrogen gas: molH2/mol mole fraction of nitrogen gas: molN2/mol What is the flow rate of gas leaving the separator? flow rate: molgash What is the flow rate of gas in the recycle line? flow rate: molgash
