2020年1月1日 · An RFCC is distinguished from a conventional gas oil FCC in the quality of the feedstock. The common definition of residue is the fraction of the feed that boils above 1050 °F (565 °C) and concarbon residue levels greater than 0.5 wt%. The residue content of RFCC feeds typically ranges from 1.0 to 6.0 wt%. Aside from its residue concentration ...

UOP licensed catalytic cracking processes include the fluid catalytic cracking (FCC) process, the Resid FCC (RFCC) process, MSCCSM process and the PetroFCCSM process. All of these processes convert gas oil and heavier streams to lighter, more valuable products via high-temperature catalytic cracking.

2014年12月15日 · RFCC is an extension of conventional FCC process, processing the heavier feedstock, and RFCC technology got great development around the reaction system, including the feeding atomization, quick separation of oil vapor and spent catalysis, steam stripping of high efficiency, temperature control of reaction as well as the innovation of riser ...

This article explores the technical challenges and opportunities presented when targeting high propylene production from a residual fluid catalytic cracking (RFCC) unit. The discussion will focus on the operation of propylene-targeted grassroots RFCC units designed by UOP and commissioned in the past few years.

The Fluid Catalytic Cracking (FCC) and Resid FCC (RFCC) processes have long been trusted workhorses in the refining industry to meet the demand for motor fuels. The FCC/RFCC processes utilize a powdered catalyst that continuously circulates between a short contact time reaction zone (riser) and a higher temperature regeneration zone where coke ...

2014年1月1日 · RFCC is an extension of conventional FCC process, processing the heavier feedstock, and RFCC technology got great development around the reaction system, including the feeding atomization,...

1998年8月27日 · Protection of zeolites by metal scavengers then became an important field in RFCC catalyst development. Dedicated metal traps, scavengers and/or additives (solid catalyst and/or feed additives as Sb, Bi, Sn, etc.) were developed and commercialized in order to combat the negative effect of metals, mainly vanadium (V) and nickel (Ni).

We supply residue fluid catalytic cracking (RFCC) and fluid catalytic cracking (FCC) units. These comprise reactor and regenerator, pipework, pressure-retaining spare parts, internals such as combustor risers and other components such as orifice chambers.

RFCC Abbreviation Meaning. RFCC stands for Ready For Commissioning Certificate, a document that signifies that a project or system is fully prepared and meets all necessary requirements to begin operations. This certificate is often utilized in engineering and construction industries to ensure compliance with standards.

2020年3月1日 · The catalyst can be used to effectively remove sulfur and residue carbon from the feedstocks of RFCC units, therefore improving the performances and product qualities of the RFCC units. Physical and Chemical Properties:
