PEP Review 80-1-1
Supplementary LPG Feed for Naphtha Crackers
The economics of replacing 10% and 20% of the naphtha feedstock with LPG in a 1,000 million lb/yr ethylene plant are evaluated on the basis of conditions on the U.S. Gulf Coast. The potential production cost savings at current prices are estimated for 10% and 20% naphtha replacements, respectively. Cost curves are presented to correlate the ethylene value (net production cost plus a 25%/yr pretax ROI) with feedstock prices.
