Maximizing light cycle oil recovery in the FCC main fractionator

Refiners operating FCCU's have adjusted their operating strategies to maximize light cycle oil production to meet the increased demand for automotive diesel. Catalyst formulations and reactor conditions can alter yields, but the refinery cannot take full advantage of the increased LCO recovery without an optimized Main Fractionator operation and design. Sulzer offers several methods of optimizing the separation between light cycle oil and less valuable HCO or slurry with little ...

NEKTOR™ 4G incorporates new technologies that were developed during the extensive Grace R&D program that was initiated as a result of the tight oil ...

Oil sands crude — profits and problems?

Canadian bitumen production currently runs about 1 MMbpd, with some being sold as Synbit and Dilbit. Over the next 10-12 years output is expected to increase to 3.5 MMbpd and more refiners will begin investing to process it and come to depend on the Synbit and Dilbit for a significant part of their supply. Few today, however, have ever processed these feeds at high blend ratios, and are unaware that conventional process and equipment designs are not up to the job. Canadian oil ...

On budget, on time, offline

Flawless project execution will not prevent a unit shutdown due to selecting the wrong metallurgy for a challenging crude slate. No matter how well it is fabricated and installed, a shell and tube exchanger with cold, high viscosity vacuum resid on the tube side will have poor heat transfer performance. On-time shipping and installation of a too-small desalter will not prevent crude column overhead corrosion if the centerline velocity is overly optimistic for the design crude. A ...

ResidCrackeR™ 4G

ResidCrackeR™ 4G is the latest generation of Grace’s coke selective bottoms cracking ResidCrackeR™ catalyst family for residue FCC feed applications. ResidCrackeR™ 4G is an extension of the ResidCrackeR™ catalyst family, a component of the EnhanceR™ technology platform, which is the market leader in the EMEA region. ResidCrackeR™ 4G incorporates new technologies that were developed during the extensive Grace R&D program that was ...

RIVE® FCC Catalysts

RIVE® FCC catalyst represents the first and only use of ordered mesoporosity in FCC zeolites or catalysts, and is capable of providing a step change in value for many FCC operations. The result: enhanced diffusion of hydrocarbons both into and out of the catalyst particle. This adds options to process heavier feeds, reduce feedstock costs, circulate more catalyst, and preserve valuable products increasing operating flexibility for the refiner.

SMOOTHFLOW™ FCC additive

The solution for FCC fluidization and circulation problems. SMOOTHFLOW from Ketjen offers a solution to FCC unit fluidization and circulation problems. Fluidization problems sometimes begin suddenly, often as the result of an unexpected process upset causing significant catalyst losses and possible mechanical damage inside the unit. The finest catalyst particles in the circulating inventory are usually lost first, which results in a sharp increase in the equilibrium catalyst average ...

SOxMASTER-2™

Optimal SOx reduction without rare earth for partial- and full-burn units. SOx reduction additives are designed to capture and remove the oxidized sulfur compounds present in the FCC unit regenerator and release them in the FCC riser. On release, the sulfur exits the FCC unit as hydrogen sulfide, along with the cracked products in the reactor effluent. The hydrogen sulfide is processed in the gas plant downstream of the FCC unit. Extensive studies in the 1970s looked at the ...

Squeeze more value out of your FCC gasoline

As sulfur legislations tighten, it becomes more difficult for refiners to meet the specifications from their FCC gasoline post-treatment units. Particularly the octane number poses challenges, since some olefins are simultaneously being hydrogenated. The consequent loss of octane often prevents the refineries from achieving maximum value. Topsoe’s series of HyOctane™ catalysts are specifically developed for all steps in FCC gasoline post-treatment applications. ...

Tracerco Diagnostics™ Distribution study - FCC stripper

Uniform distribution of catalyst and steam in a stripper is critical to achieve high stripping efficiency (less carry-down of hydrocarbon products from reactor to regenerator). A failure to effectively remove hydrocarbon from the catalyst will result in a loss of product, lower throughput, and lower catalyst activity due to increased regenerator bed temperature. The Field Test Tracerco was contacted to conduct distribution studies for a leading refiner that was experiencing ...

Tracerco Diagnostics™ FCCU Study

See inside your Operations. The Fluidised Catalytic Cracking Unit (FCCU) is the economic heart of a modern refinery.
