Witryna20 mar 2007 · Abstract. Over 95% of butadiene is produced as a by-product of ethylene production from steam crackers. The crude C4 stream isolated from the steam cracking process is fed to butadiene extraction units, where butadiene is separated from the other C4s by extractive distillation. The amount of crude C4s produced in steam cracking … Witrynacompare that process in detail with traditional naphtha cracking. In particular, we lay out side by side crude oil vs. naphtha comparisons of yield sets, major equipment sizes, and process economics. Our analysis indicates that the ExxonMobil process achieves a $100-$200/ton cost advantage vis-à-vis naphtha cracking

Witrynarates of the steam cracker and the type of feedstock. The propylene yield from steam cracking is directly proportional to the average molecular weight of the feed [19]. In the past, propylene was produced from steam crack-ing of naphtha and, as a result, propylene was available in substantial amounts. However, most modern steam crack- WitrynaFor instance, the process to hydrotreat naphtha is not the same as the process for diesel fuels.
