Biorefineries: Fact or fiction?

Technology advances facilitate building integrated chemical complexes based on renewable feedstocks that can cost-effectively process ethylene derivatives

Bruscino, M., Scientific Design Co.

  Integrated complexes for petroleum-derived processes are common. However, the same types of complexes are not typical for processes based on bio-renewable feedstocks. New technology advancements overcome processing hurdles that allow cost-effective production of ethanol-derived ethylene derivatives that can compete with traditional processing methodologies. Background. Over the last 90 years, feedstocks for most downstream petrochemicals are petroleum based. Due to rising prices of crude oil and concerns over the environment, renewed interest for applying alternative feedstocks—in particular, bio-renewable feedstocks—has emerged. Among the many bio-derived feedstocks, et
