Extracted text: Sunflower oil contains 0.080 mol palmitic acid (C1,H„0,)/mol, 0.060 mol stearic acid (C13H3,0,)/mol, 0.25 mol oleic acid (C3H2,0,)/mol, and 0.61 mol linoleic acid (C13H2,0,)/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. C18H340, + H, C13H3,0, C18H320, + 2 H, CH3,02 ´18 At a margarine production facility, a stream of 445.0 mol sunflower oil/h is fed into a reactor. The fresh hydrogen source available is a mixture containing 0.96 mol H,/mol and 0.040 mol N,/mol. N, is inert in this process. To ensure complete hydrogenation, the hydrogen gas mixture is introduced into the reactor in 55.0% 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 110.0 mol gas/h of this recycle stream is purged to prevent the buildup of nitrogen gas.
