Sunflower oil contains 0.070 mol palmitic acid (C16H32O2)/mol, 0.060 mol stearic acid (C18H3602)/mol, 0.29 mol oleic acid (C18H3402)/mol, and 0.58 mol 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. C13H,0, + H, → C18H3,02 2 C13 H,0, +2H, → C,H3,O, At a margarine production facility, a stream of 360.0 mol sunflower oil/hr is fed into a reactor. The fresh hydrogen source available is a mixture containing 0.98 mol H2/mol and 0.020 mol N2/mol. (N2 is inert in this process.) To insure complete hydrogenation, the hydrogen gas mixture is introduced into the reactor in 60.0% excess. All reaction products leave the reactor and proceed to a separator where palmitic and stearic acids are separated from the hydrogen gas mixture.
