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.

In practice, the cxr the content of naphtenes in the naphtha feedstock, the better will be the quality of the reformate and the higher the production of hydrogen. However, both the dehydrogenation of naphthenes and the dehydrocyclization of paraffins produce hydrogen. Fans for these applications are critical to the process and therefore need to be extremely reliable to minimize costly downtime. The resulting liquid—gas mixture platfroming preheated by flowing through a heat exchanger.

Petroleum Refining Technology and Economics 2nd ed. Please complete the fields below to get your platfforming. 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 future products.

The benzene extracted can be marketed as feedstock for the chemical industry. As the leading global supplier of fans for this application, Howden has installed hundreds of fans for the catalyst regeneration process around the world. Every fan we manufacture for high pressure catalyst regeneration is built and tested to withstand psi kPa hydrostatic pressure. 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.

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.

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. It can also be used to improve the octane rating of short-chained hydrocarbons by aromatizing them.

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.

The first unit operation in a refinery is the continuous distillation of the petroleum crude oil being refined. Catalytic reforming has a limited ability to process naphthas with a high content of normal paraffins, e. Therefore, the naphtha feedstock pkatforming a catalytic reformer is always pre-processed in a hydrodesulfurization unit which removes both the sulfur and the nitrogen compounds.

UOP CCR PLATFORMING

The hot reaction products from the third reactor are partially cooled by flowing through the heat exchanger where the feed to the first reactor playforming preheated and then flow through a water-cooled heat exchanger before flowing through the pressure controller PC into the gas separator. Some refineries may also desulfurize and catalytically reform those naphthas.

That offgas is routed to the refinery’s central gas processing plant for removal and recovery of propane and butane. Temperature and vibration monitoring equipment is also available to provide long term protection and reliability for the monoblock bearing assembly. As the vaporized stream proceeds through the three reactors, the reaction rates decrease and the reactors therefore become larger.

As a charter member of AMCA, Howden has contributed to setting many of the standards used throughout the industry today.

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. It is the straight-run heavy naphtha that is usually processed in a catalytic reformer because the light naphtha has molecules with 6 or fewer carbon atoms which, when reformed, tend to crack into butane and lower molecular weight hydrocarbons which are not useful as high-octane gasoline blending components.

Quality and performance is in our DNA Howden Garden City Fans was one of the first manufacturers to develop a product for the platforming process and has been a global market leader for over 40 years. The catalyst regeneration process allows continuous regeneration of a controlled quantity of catalyst and is used for reforming applications by refineries. This page was last edited on 11 Decemberat Such units are defined. This is driving the emergence of new technologies to process naphtha into gasoline by companies like Chevron Phillips Chemical Aromax [16] and NGT Synthesis Methaforming [17][18].

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. 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.

From Wikipedia, the free encyclopedia. When that reactor is regenerated, it replaces another reactor which, in turn, is isolated so that it can then be regenerated. Catalytic reforming is a chemical process used 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.

This contributes both to costs and the emissions of the process.

Schematic diagram of a typical semi-regenerative catalytic reformer unit in a petroleum refinery. The temperature again decreases across the second reactor and the vaporized stream must again be reheated in the third fired heater before it flows through the third reactor.

UOP CCR PLATFORMING

Before describing the reaction chemistry of the catalytic reforming process as used in petroleum refineries, the typical naphthas used as catalytic reforming feedstocks will be discussed.

Haensel’s process was subsequently commercialized by UOP in for producing a high octane gasoline from low octane naphthas and the UOP process become known as the Platforming process. Also, not all refineries process the same crude oils and each refinery produces its own straight-run naphthas with their own unique initial and final boiling points.

The lumping technique is used extensively for reducing complexities so that the lumps and reaction pathways that properly describe the reforming system and kinetic rate parameters do not depend on feedstock composition.

Fresh catalyst is chlorided chlorinated prior to use.
