Fluid and Flexi-Coking. Fluid coking and flexi-coking are fluid-bed processes developed from the basic principles of FCC, with close integration of endothermic (cracking, coking, or gasification) and exothermic (coke burning) reactions. In fluid coking and flexi-coking processes, part of the coke product is burned to provide the heat necessary ...
Previous study found that the oil-sands fluid coke could reduce SO 2 to produce the by-products of elemental sulfur, at the temperature of 600–900 °C. The reaction is shown as Formula (5) [58] . Furtherly, the SO 2 modified petroleum coke is used to prepare the …

Three different coking processes are used in the refineries: delayed coking, fluid coking, and flexi-coking (a variation of fluid coking). The common objective of the three coking processes is to maximize the yield of distillate products in a refinery by rejecting large quantities of carbon in the residue as solid coke, known as petroleum coke.
Simplified schematics of the fluid-coking and flexi-coking processes are shown in Fig. 1, Fig. 2, respectively .The difference between processing conditions is evident from the different properties of the fluid-coke and flexi-coke as shown in Table 1 and Table 2, i.e., it is evident that flexi-coke was subjected to more severe conditions.The main difference includes parameters such as the ...

The grinding will also dull the sharp end of the synchronizer sleeve splines and the gear dog teeth, and wear here contributes to bad synchroniser performance and hard shifting. Jumping out of gear may be the result of any number of the internal and external problems. End play or preload problems with individual gears on the mainshaft are two ...

This page is about the Crusher added by Immersive Engineering. For other uses, see Crusher. The Crusher is a 3×5×3 multiblock added by Immersive Engineering. It is used for crushing ores into grit, which is more efficient than normal smelting. Once the blocks are assembled, use the Engineer's Hammer on the center of the front of the longer side (which should be a Steel Fence with a Hopper ...

Apparatus for and method of reducing spherically shaped fluid coke waste by-product pellets into a pulverized condition for use as a fuel in which there is a first grinding and pulverizing mill initially receiving the waste material which, because of its spherical shape is difficult to pulverize, and accordingly the waste material is transported to a second grinding mill where its spherical ...
Vibratory Screens. A leader in separation technology, General Kinematics screens can be found worldwide in a large variety of industries. From the separation of heavy ores, molten hot castings and sand, to paper products and everything in between. GK has made waves in the processing equipment industry using Two-Mass screening technology.
Answer: Petroleum coke is a product obtained by the separation of light and heavy oil by distillation and the thermal cracking of heavy oil. It is the "waste" at the end of the petroleum refining process. According to different forms, it can be divided into needle coke, projectile coke or spheric...
Excessive fluid is not usually due to drinking a lot of liquids although this may plays some part in it. During digestion the bowel secretes fluid from within the body into the digestive tract. This aids with the digestive processes and the fluid is then reabsorbed back into body in the colon leaving behind a soft but solid stool. Any substance ...
Effect of jet engine oil coking. Coke is the solid residue created when oil undergoes severe oxidative and thermal breakdown at extreme engine temperatures. The higher the temperature, the harder, blacker and more brittle the coke/deposit residue.
Grinding fluid also acts as a coolant, and even oil has some heat-transfer capability, but not as much as water-based coolants. "Material removal is increased by the reduction in specific energy, which allows the stock removal rate to go up without increasing the surface damage to …

processes such as grinding substantially increase the percent of rhombohedral structure found in the other-wise hexagonal structure. Amorphous carbon is also referred to as nongraphitic carbon. When examined by X-ray diffraction, these materials show only diffuse maxima at the normal scattering angles. This has been attributed to a ran-

Fluid/flexi-coking technology is a front runner among the technologies for the upgrading of heavy feeds to transportation fuels. Depending on properties, in the case of vacuum residues, the conversion to liquid fractions can approach 70% of the feed. A high heating value gas and coke account for the remaining feed.
