CONTINUOUS CATALYTIC REGENERATION (CCR) | Energy Efficiency Guidelines in Refinery

CONTINUOUS CATALYTIC REGENERATION (CCR) – The Continuous Catalyst Regeneration Platformer Plant CCR Platformer) produces 101 Research Octane Number (RON) reformate, with a maximum 3.5 psi RVP, as a blending stock in the gasoline pool. It has the flexibility to process blends of Naphtha from the Crude Unit, Gas Condensate Splitter, Hydrocracker, LSRN and Visbreaker Plants. It consists of CCR Platformer to produce reformate product.

The CRR process is normally accompanied by NHT processes to produce desulfurized feed for the CCR plat-former and gasoline blending. It employs a suitable catalyst and hydrogen to remove organic sulfur and nitrogen components that are detrimental to the CCR Platformer Catalyst. The naphtha splitter separates the hydro-treated naphtha into a light fraction (C5-180ºF) as a sweet naphtha product and a heavy fraction (180-360ºF TBP cut) as feed to the CCR Platformer.

The CCR Platformer, consisting principally of a Platformer and a Continuous Catalyst Regenerator (CCR), processes up to 50,000 BPD of hydro-treated naphtha into a 101 RON gasoline blending stock.

The Platformer is a low pressure (50 psig) catalytic process. Under a hydrogen-rich
atmosphere, the Platformer converts the low-octane components in the naphtha feed into
high-octane aromatic compounds. The yield of reformate from the Platformer is about
80 volume percent. This process is a net producer of hydrogen and LPG.

The CCR continuously regenerates Platformer catalyst. Air is used to burn off coke
deposited on the catalyst surface, during the Plat-forming operation. The catalyst is
circulated continuously in a closed loop system between the reactors and the regenerator.

Thus, the catalyst activity and product yields are effectively maintained at a constant level throughout the catalyst life. Catalyst fines created by attrition are collected in a dust collector and the combustion gas is scrubbed free of chloride before being vented to the atmosphere. Plat-former catalyst has a typical life of about three years before replaced with a new charge.

The Naphtha Hydrotreater/Continuous Catalyst Regeneration Platformer Plant (NHT/CCR Platformer) produces 101 Research Octane Number (RON) reformate, with a maximum 3.5 psi RVP, as a blending stock in the gasoline pool. It has the flexibility to process blends of Naphtha from the Crude Unit, Gas Condensate Splitter, Hydrocracker, LSRN and Visbreaker Plants. It consists of a NHT and Splitter to desulfurize, and prepare Platformer feedstock and CCR Platformer to produce reformate product.

The NHT processes 69,000 BPD naphtha to produce desulfurized feed for the CCR
platformer and gasoline blending. It employs a suitable catalyst and hydrogen to remove
organic sulfur and nitrogen components that are detrimental to the CCR Platformer Catalyst.
