FCC PROPYLENE PRODUCTION AND TECHNOLOGY ALTERNATIVES TO OPTIMIZE PROPYLENE YIELDS

摘要

According to Purvin & Gertz(4), global FCC capacity is projected to grow by approximately 19% between 2006 and 2015. Across that same time, polymer grade propylene production from FCC units is projected to grow by nearly 32%(3). Although the current average propylene yield from the installed FCC base is 4 to 5 wt%, (weight percent of fresh feed to the FCC unit) many of the new FCC units that come on line over the next ten years will produce even higher propylene yields, some projected to be as high as —20 wt%.
