4. Acetylene (C2H2) is used in the polymer industry as a starting raw material to form compounds such as acrylic acid, 1,4-butanediol, and acrylonitrile. Those compounds are then used to produce polymers that find use in various applications including the production of diapers, synthetic fabric spandex, and paint. In one polymer processing plant, 200mol/hr of acetylene (C2H2) is needed at 127C as a feed to a catalytic reactor. An acetylene stream is available at 27C to heat is available. For this purpose, determine the heat duty of the pre-heater. (Watch "Acetylene heating. mp4 )
