Slurry oil is the lowest-value stream produced by an FCCU, representing only 3-7 vol % of the total products. A typical 50,000 b/cd FCCU would produce as by-product 2,000 b/cd or 125,000 tonnes ...

RESPONSE If the slurry is off of an FCCU you should NOT return the slurry to the crude tank. Charging a crude unit with cracked oil can put your products off of color specs. If your refinery has a coker that is the best place for for the slurry since it is cracking heavy oil anyway.

Mar 28, 2017 · Slurry Oil/Catalyst Fines Tank Bottoms Recovery & Processing. The problems presented by catalyst attrition from fluid catalytic cracking units (FCCU) have plagued the refining industry since the advent of fluid catalytic cracking in the first half of the 20th century. Over time, FCCU catalyst deteriorates in size.

Fluid Catalytic Cracking Units (FCC Cyclones) are the principal technologies that enable the critical process within heavy oil refining of converting the heavy oils into more valuable gasoline and lighter products. More than half of the refinery's heavy petroleum is processed through the FCC Cyclones, and the FCC Cyclones are also an important source of butene and pentene olefins used in ...

The filter system is designed for continuous operation with both filters on-line except when one filter is off-line for backwash. The backwash receiver provides surge volume to contain

Slurry oil is a saleable product of FCCU processing. Once in the storage tank, the catalyst fines settle to the bottom, albeit very slowly. The existence of catalyst fines in the slurry tank presents a variety of problems to the refiner. The immediate and obvious problem has to do with product contamination.

RESPONSE If the slurry is off of an FCCU you should NOT return the slurry to the crude tank. Charging a crude unit with cracked oil can put your products off of color specs. If your refinery has a coker that is the best place for for the slurry since it is cracking heavy oil anyway.

S 01, 4001 Activated Carbon / Anthracite Filter System It is Reverse Washing Type of Filtration System to use jointly a physical absorption and a heap filter to insert a carbon or anthracite. In case of liquid phase, mainly it is used to a clean water treatment.

Ash is a particular problem for slurry, especially those oils that are heavy and viscous needing long residence time to allow for catalyst settling. Obtaining low ash (less than 0.05 wt %) requires such special techniques as heating, chemical additives, filters, electrostatic precipitators, centrifuges, and cyclones.

The first membrane filters were put into slurry oil service around 1990. Mechanical filtration operates at temperatures up to 600 ˚F and employs tubular porous metal elements. The solids collect on the inside of the elements while the filtrate passes through to the outside. Some filter systems use porous sintered

hazardous waste. Depending on the tank size and rate of slurry oil production, treatment and disposal cost estimates are US$1 – 4 million per cleaning. In the absence of countermeasures, increasing resid feed to the FCCU will increase the rate of slurry oil production and sludge formation.6 Membrane filters were first put into slurry oil service

Fluid catalytic cracking Process overview Fluid catalytic cracking (FCC) is an important and widely used process to convert heavy feedstock into lighter, more valuable, products. Various feedstocks can be used such as gas oils, vacuum gas oils or residual materials. Typical products are gasoline, light fuel oils and olefin-rich gases.

The third type of classification used in mining is the Hydrocyclone, commonly called a Cyclone. Unlike the others it has no moving parts and is worked in conjunction of another piece of equipment, a pump. To understand the Hydrocyclone Working Principle we must first know its components. Beginning at the top, there is the OVERFLOW DISCHARGE.
