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.

Fans for this process are manufactured for lasting performance due to their purposeful design with rigid double walls, and filled with high density insulation.
Some installations use three separate fired heaters as shown in the schematic diagram and some installations use a single fired heater with three separate heating coils. Reformate can be blended directly in the gasoline pool plxtforming often it is separated in two or more streams.
The liquid feed at the bottom left in the diagram is pumped up to the reaction pressure 5—45 atm and is joined by a stream of hydrogen-rich recycle gas. There are many chemical reactions that occur in the catalytic reforming process, plagforming of which occur in the presence platforing a catalyst and a high partial pressure of hydrogen.
You can help by adding to it. Such units, referred to as cyclic catalytic reformers, are not very common. Brazilian Journal of Chemical Engineering. At the same time, the amount of reheat required between the reactors becomes smaller. Owing to too many components in catalytic reforming process feedstock, untraceable reactions and the high temperature range, the design and simulation of catalytic reformer reactors is accompanied by complexities.
UOP CCR PLATFORMING
Crude oils containing the best naphtha plqtforming reforming are typically from Western Africa or the North Sea, such as Bonny light oil or Norwegian Cr. The naphtha from the crude oil distillation is often further distilled to produce a “light” naphtha containing most but not all of the hydrocarbons with 6 or fewer carbon atoms and a “heavy” naphtha containing most but not all of the hydrocarbons with more than 6 carbon atoms. The benzene extracted can be marketed as feedstock for the chemical industry.
This contributes both to costs and the emissions of the process.
Very few, if any, catalytic reformers currently in operation are non-regenerative. Throughout the process, controlled audit procedures monitor the efficiency of our operation. This page was last edited on 11 Decemberat This quality assurance is integral to our leadership in the industry. The higher the severity of the reacting conditions temperaturethe higher is the octane of the produced reformate but also the shorter will be the duration of the cycle between two regenerations.
Standard fan features include a custom fabricated monoblock bearing assembly, nitrogen purged Shaft Seal, and custom designed fan wheels with a focus on efficiency and reliability.
We have worked with many OEMs and research groups to design new equipment on the leading edge of energy research, oil refining, and other products and processes to meet the needs of the industry in the future. Petroleum Refining Technology and Economics 2nd ed. The heavy reformate is high in octane and low in benzene, hence it is an excellent blending component for the gasoline pool. Some catalytic reforming units have an extra spare or swing reactor and each reactor can be individually isolated so that any one reactor can be undergoing in situ regeneration while the other reactors are in operation.
The process converts low-octane linear hydrocarbons paraffins into branched alkanes isoparaffins and cyclic naphtheneswhich are then partially dehydrogenated to produce high-octane aromatic hydrocarbons.
The hot reaction products from the third reactor are partially cooled by flowing through the heat exchanger where the feed to the first reactor is preheated and then flow through a water-cooled heat exchanger before flowing through the pressure controller PC into the gas separator. The isomerization of normal paraffins does not consume or produce hydrogen.
The overhead liquid distillate is called naphtha and will become a major component of the refinery’s gasoline petrol product after it is further processed through a catalytic hydrodesulfurizer to remove sulfur -containing hydrocarbons and a catalytic reformer to reform its hydrocarbon molecules into more complex molecules with a higher octane rating value. If you would like to submit an enquiry please get in touch.
Catalytic reforming is a chemical process fcr to convert petroleum refinery naphthas distilled from crude oil typically having low octane ratings into high-octane liquid products called reformateswhich are premium blending stocks for high-octane gasoline.
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.
Various bearing lubrication methods are available for the monoblock bearing assembly including static oil, forced lubrication, or oil mist lubrication.
Continuous Catalyst Regeneration (CCR) Platforming | Howden
However, both the dehydrogenation of naphthenes and the dehydrocyclization of paraffins produce hydrogen. 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 platfomring for your changing operation. Reliable fans for catalyst regeneration process. It should be noted that there are a great many petroleum crude oil sources worldwide and each crude oil has its own unique composition or “assay”.
Catalytic reforming requires a whole range of other processing units at the refinery apart from the distillation tower, a naphtha hydrotreater, usually an isomerization unit to process light naphtha, an aromatics extraction unit, etc.
This process is quite different from and not to be confused with the catalytic steam reforming process used industrially to produce products such as hydrogenammoniaand methanol from natural gasnaphtha or other petroleum-derived feedstocks.
Some refineries may also desulfurize and catalytically reform those naphthas. However, for the most part, catalytic reforming is mainly used on the straight-run heavy naphthas, such as those in the above table, derived from the distillation of crude oils. The light reformate has lower octane and can be llatforming as isomerization feedstock if this unit is available.

Top manufacturing capabilities and project management support. Usually, three reactors are all that is required to provide the desired performance of the catalytic reforming unit. The four major catalytic reforming reactions are: Every fan we manufacture for high pressure catalyst regeneration is built and tested to withstand psi kPa hydrostatic pressure.
Most catalytic reforming catalysts contain platinum or rhenium on a silica or silica-alumina support base, and some contain both platinum and rhenium. It can also be used to improve the octane rating of short-chained hydrocarbons by aromatizing them. During the fan fabrication process, we design, construct and test to the highest quality.
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. Our catalyst regeneration process AMCA test laboratory continually conducts performance tests, sound measurement, and llatforming analysis to meet our current needs, as well as developing future products.
The residual gas after such processing becomes part of the refinery’s fuel gas system. As a charter member of AMCA, Howden has contributed to setting many of the standards used throughout the cvr today. 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.
Every Garden City high temperature fan supplied by Howden is thoroughly inspected and tested. Some refinery naphthas include olefinic hydrocarbonssuch as naphthas derived from the fluid catalytic cracking and coking processes used in many refineries.
