Crude oil to ethylene in one step
Reports that the most important feature of the partial combustion cracking (PCC) process is its ability to convert heavy petroleum fractions to light olefins with minimum residue. Presents diagram of the PCC process; graph of feedstock cost vs. return on investment (ROI); and tables with average ethylene yields, cracking yields, and PCC vs. LPG and naphtha cracking. Finds that the 10% difference in capital between the PCC and the naphtha feed case is due mainly to the cost of the acid gas and sulfur handling sections required for the PCC, but not for a naphtha cracker. The very favorable ROI and ethylene costs are due to the relative difference in feedstock pricing. Sensitivity of ROI to changes in feedstock was also studied for the PCC cases. The ratio of cost of high-sulfur fuel oil (HSFO) to average crude price is used to indicate the substantial effect of feedstock price on the attractiveness of the project. Concludes that with HSFO at 85 to 100% of crude value, the PCC represents an excellent investment for future ethylene needs.
