CCR PLATFORMING PDF
Continuous Regenerative (moving bed) CCR Platforming – UOP Process. In this process, three or four reactors are installed one on the top of the other. Our Garden City RF2 fans are perfect for Continuous Catalyst Regeneration in oil refineries. We set the standards for the chlorination and regeneration blowers. This course provides an overview of the CCR Platforming unit with a CycleMax or pressurized regenerator. The principles of catalyst regeneration and.

Rate equations of this type explicitly account for the interaction of chemical species with catalyst and contain denominators in which terms characteristic of the adsorption of reacting species are presented. The naphtha is a mixture of very many different hydrocarbon compounds.
It can be seen that they differ significantly in their content of paraffins, naphthenes and aromatics:. Crude oils containing the best naphtha for reforming are typically from Western Africa or the North Sea, such as Bonny light oil or Norwegian Troll.
The process flow diagram below depicts a typical semi-regenerative catalytic reforming unit. Also, the molecules with 6 carbon atoms tend to form aromatics which is undesirable because governmental environmental regulations in a number of countries limit the amount of aromatics most particularly benzene that gasoline may contain.
UOP CCR PLATFORMING
With over 40 years of supplying fans, our Garden City brand of specialist fans continues to set the standard for the chlorination and regeneration and cooler blowers used in the catalyst regeneration process. Standard fan features include a custom fabricated monoblock bearing assembly, nitrogen purged Shaft Seal, and custom platfkrming fan wheels with a focus on efficiency and reliability.
Schematic diagram of a typical semi-regenerative catalytic reformer unit in a petroleum refinery. Views Read Edit View history. To maintain the required reaction temperature and the rate of reaction, the vaporized stream is reheated in the second fired heater before it flows through the second reactor. Platformihg is driving the emergence of new technologies to process naphtha into gasoline by companies like Chevron Phillips Chemical Aromax  and NGT Synthesis Methaforming .
Fans for this process are manufactured for lasting performance due to their purposeful design with rigid double walls, platcorming filled with high density insulation.
UOP CCR PLATFORMING
As the leading global supplier of fans for this application, Howden has installed hundreds of fans for the catalyst regeneration process around the world. In the years since then, many other versions of the process have been developed by some of the major oil companies and other organizations. During the reforming reactions, the carbon number of the reactants remains unchanged, except for hydrocracking reactions which break down the hydrocarbon molecule into molecules with fewer carbon atoms.
This quality assurance is integral to our leadership in the industry. Webarchive template wayback links All articles with unsourced statements Articles with unsourced statements from May Articles to be expanded from December All articles to be expanded Articles using small message boxes.
Continuous Catalyst Regeneration (CCR) Platforming.
We can do it Our high temperature experts can advise you on modifying your present equipment for new applications or temperatures; in addition we can design new equipment for your changing operation.
Our products are designed according to recognized global industry standards for the continuous regeneration cccr.
The most commonly platformihg type of catalytic reforming unit has three reactorseach with a fixed bed of catalyst, and all of the catalyst is regenerated in situ during routine catalyst regeneration shutdowns which occur approximately once each 6 to 24 months. Indeed, if not chlorinated or insufficiently chlorinated the platinum and rhenium in the catalyst would be reduced almost immediately to metallic state by the hydrogen in the vapour phase.
It can also be used to improve the octane rating of short-chained hydrocarbons by aromatizing them. Brazilian Journal of Chemical Engineering. Most catalytic reforming catalysts contain platinum or rhenium on a silica or silica-alumina support base, and some contain both platinum and rhenium. The sensitivity of catalytic reforming to contamination by sulfur and nitrogen requires hydrotreating the naphtha before it enters the reformer, adding to the cost and complexity of the process.
Oil refining Chemical processes. Petroleum Refining Technology and Economics 2nd ed. Garden City Fans are designed with quality and total cost of ownership in mind; and with service centers around the world, we remain committed to provide the parts and service our customers need to mitigate downtime.
Our catalyst regeneration process AMCA test laboratory continually conducts performance tests, sound measurement, and stress analysis to meet our current needs, as well as developing pllatforming products.
Main licensors of catalytic reforming processes, UOP and Axens, constantly work on improving the catalysts, but the rate of improvement seems to be reaching its physical limits.
Continuous Catalyst Regeneration (CCR) Platforming | Howden
The lumping technique is used extensively for reducing complexities so that the lumps and reaction pathways that properly describe playforming reforming ;latforming and kinetic rate parameters do not depend on feedstock composition. The reformate has a much higher content of benzene than is permissible by the current regulations in many countries. At the same time, the amount of reheat required between the reactors becomes smaller.
The liquid from the gas separator vessel is routed into a fractionating column commonly called a stabilizer. Non-Destructive Test NDT procedures such as magnetic particle, liquid dye penetrant, radiograph, and ultrasonic testing are used to ensure the quality of the welds. The manufacturing process is initiated by a testing and traceability procedure used to check the quality of the alloy rich materials used to fabricate your fans for conventional and high pressure catalyst platforminv process fans.
The naphtha from the crude oil distillation is often further distilled to produce a “light” naphtha containing most but not platforjing of the hydrocarbons with 6 or fewer carbon atoms and a “heavy” naphtha containing most but not all of the hydrocarbons with ;latforming than 6 carbon atoms.
Every Garden City high temperature fan supplied by Howden is thoroughly inspected and tested. Nor is this process to be confused with various other catalytic reforming processes that use methanol or biomass-derived feedstocks to produce hydrogen for fuel cells or other uses.
