Producing 300 Million Pounds per Year of Ethylene in a Plug-Flow Reactor: Design of a Full-Scale Tubular Reactor Ethylene ranks first in the United States in total pounds of organic chemicals produced each year, and it is the number-one organic chemical produced each year.Over 60 billion pounds were produced in 2010, and it sold for $0.37 per pound.Sixty-five percent of the ethylene produced is used in the manufacture of fabricated plastics, 20% for ethylene oxide, 16% for ethylene dichloride and ethylene glycol,5% for fibers, and 5% for solvents. Determine the plug-flow reactor volume necessary to produce 300 million pounds of ethylene a year by cracking a feed stream of pure ethane. The reaction is irreversible and follows an elementary rate law. We want to achieve 80% conversion of ethane, operating the reactor is othermally at 1100 K and at a pressure of 6 atm. The specific reaction rate at 1,000 K is 0.072 s –1 and the activation energy is 82,000 cal/mol.
