Deep catalytic cracking, maximize olefin production
- Stone Webster Engineering Corp., Houston, TX (United States)
Recent environmental regulations coupled with lead phase out have shifted the focus of the FCC from that of an octane barrel machine to that of a light olefins generator. The light olefins are the necessary feedstock for premium reformulated gasoline (RFG) blending components such as MTBE, TAME and alkylate. The demand for these light olefins will impact the operation of the FCC and Steam Cracker (SC). There will be a need for economical olefin generating processing alternatives to supplement SC's for C[sub 3]= and FCC's for C[sub 3]= through C[sub 5]= RFG component feedstocks. To this end, Stone Webster has recently entered into an agreement with the Research Institute of Petroleum Processing (RIPP) and Sinopec International, both located in the People's Republic of China, to exclusively license RIPP's Deep Catalytic Cracking (DCC) technology outside of China. DCC is a newly developed catalytic cracking process for producing light olefins (C[sub 3]--C[sub 5]) from heavy feedstocks. DCC is a fluidized bed process for selectively cracking a variety of hydrocarbon feedstocks to light olefins. Unlike s steam cracker, the predominate products are propylenes and butylenes, the direct result of catalytic cracking rather than free radical thermal reactions. There are two distinct modes of DCC operation: maximum propylene (Type 1) and maximum iso-olefin production (Type 2). Each mode of operation employs a unique catalyst as well as reaction conditions.
