Catalytic Reforming - Oil Refining

Continuous Catalyst Regeneration (CCR) reformer design is similar to a ﬁxed-bed semi-regenerative design with heaters between each reactor and a recycle gas compressor in order to reduce coke make. In order to ensure a continuous operation of the unit, the catalyst must move or circulate through the reactors and the regenerator so that coke is burned and the catalyst regenerated on a continuous basis.

Cyclic Reforming utilizes a swing reactor in addition to on-oil reactors and separate regeneration system to maintain continuous operation of the reaction system, while individual reactors are regenerated in the regeneration system.

As a reactor becomes sufﬁciently deactivated, the swing reactor replaces it in the on-oil reactor series through a sequence of valve movements in the reaction and regeneration headers.

Hydrotreated naphtha feed is combined with hydrogen-rich recycle gas, preheated by heat exchange with the reactor efﬂuent and then further heated in a ﬁred heater before entering the ﬁrst reactor. As the endothermic reforming reactions cool the feed and product mixture, the efﬂuent from the ﬁrst reactor must be reheated to the required reaction temperature in a ﬁred heater before entering the second reactor, and similarly for the last reactor.

Catalysts

Reforming Catalysts

Although Catalytic Reforming technologies have advanced considerably over the last few decades, even the smallest improvements in catalyst selectivity, activity and stability have significant impact on refinery economics.

Adsorbents

Chloride Removal Adsorbents

Chloride is important in both catalytic reforming and isomerization as it helps to maintain catalytic activity over time. However, as chloride is continuously fed into these units, it also has to exit.

Adsorbents

Drying Series Adsorbents

Water removal applications are widely encountered in the industry sector. Activated alumina and molecular sieves stand at the forefront of the several different materials available on the market.

Adsorbents

Mercury Removal Adsorbents

Mercury removal from hydrocarbons is crucial due to HSE-related issues, corrosion problems and downstream catalyst poisoning.

Adsorbents

Sulfur Removal Adsorbents for Oil, Gas & Petrochemicals

Hydrogen sulfide (H₂S), COS, mercaptans or sulfides are common contaminants that must be removed from various gases and liquids such as natural gas, NGLs, LPGs, cracked gases, olefins or biogas.
