UOP innovation has driven the evolution of FCC technology and yielded specialized process design solutions that can help you attain your site’s propylene production requirements. The UOP RxPro™ process is designed to produce propylene yields greater than 20 wt% from VGO and residue based feedstocks.
Today’s modern FCC unit provides an important link between a fuels refinery and the production of light olefins and aromatics for petrochemical use. Historically designed for conversion of vacuum gas oils and residue feeds to a gasoline oriented product slate, new developments in this technology now allow for the cost effective production of valuable petrochemical intermediates.
UOP has leveraged its FCC design and operations experience and know-how to commercialize a process specifically geared for the enhanced production of propylene for petrochemical use as well as generation of traditional FCC-based fuel co-products. The PetroFCC™ process utilizes a combination of a uniquely designed FCC reactor/regenerator sections and operating conditions to enhance the yield of light olefins relative to conventional technologies. Through these design and operational changes, propylene yields of 12-16 wt% are achieved.
The newest entry to the enhanced propylene platform at UOP, the RxPro™ process, utilizes a novel multi-stage reactor configuration and advanced reactor technology elements found in conventional FCC/RFCC designs to generate propylene yields in excess of 20 wt% from both VGO and residue based feedstocks. A highly aromatic co-product stream from this process can be sent to an aromatic complex for benzene and para-xylene production. The multi-ring light cycle oil can be further processed in UOP’s LCO-X process for additional yield of BTX aromatics.
Many levels of integration can add value to your overall flow scheme. Heavy aromatics and other petrochemical byproducts can be recycled back to the unit or used for fuels blending opportunities.
Refining and petrochemical integration provides many economic benefits. For the petrochemical producer, integration provides a constant supply of attractively priced feedstock. For the refiner, integration provides the opportunity to increase product revenue and maximize project return on investment.

Light cycle oil (LCO) is a byproduct of the FCC process that offers a distinct opportunity for refiners to expand production of high-value aromatics. writing service The high level of aromatics present in LCO make it suitable for cost effective conversion to benzene, toluene and xylenes, high-value aromatics feedstocks.
The UOP LCO-X process, first licensed in 2008, utilizes elements of hydrocracking and aromatics processing technologies to help you get the most value from a major byproduct of your FCC.
