petroleum coke reduction

Since our 1976 report on petroleum coke (PEP Report 72A1) there has been considerable activity in the construction of coking units, despite the fact that the traditional outlets for high value coke have not expanded. At the same time: Throughout the industrialized world, the demand for residual fuel oil continues to decline rapidly.

Our Size Reduction machines efficiently reduce the size of industrial material such as wood, coal, limestone, gypsum, aggregates, waste materials and much more to a specified size.

This work introduces a new way to use low-cost petroleum (pet) coke as lightweight aggregate in cement mortars to make sound barriers. The feasibility of adding pet coke in cement matrix was investigated: an in-depth characterization of as-received coke and the new lightweight mortar was made.

The production of petroleum coke (petcoke) in the refineries is progressively peaking up because of the trend of processing heavy crudes and in turn, a renewed interest in delayed coking process.

The petroleum coke belongs to a group of materials with high carbon content. ... Casada, Rolle, et al. [10] investigated the influence of nickel on reduction cell anodes. Nickel alone does not significantly effect anode, but including anode butt material increased CO2, reactivity. Leach et al. [11] evaluated calcined coke

Petroleum coke, a byproduct of the petroleum-refining process, is an attractive primary or supplemental fuel for power production primarily because of a progressive and predictable increase in the production volumes of petroleum coke (1, 2). Petroleum coke is most commonly blended with coal in ...

Our crushers are installed at the refineries and at power plants that burn this fuel in fluid bed boilers. At the refineries, our equipment crushes the coke as it is cut out of the coking drums. Petroleum coke is a waste material from the refining process but has favor as a fuel.

petroleum sponge coke is produced from hydrocabon feedstock which forms shot coke in a conventional delayed coking process by blending the feedstock with another feedstock relaitely free of asphaltene to form a blended feedstock having an asphaltene content below about 15%.

Petroleum coke is a byproduct from oil refining industry and exists in four basic forms, delayed coke (green coke), calcined coke, fluid coke and flexicoke. Delayed coke is a byproduct of the delayed coker process. Calcined coke is delayed coke that has been pyrolized above 1400°C to remove the volatile part and is usually used in the ...

Effective parameters on desulfurization of petroleum coke, other than temperature, include alkali to feed (petroleum coke) mass ratio, time and mesh size in the ranges of 0.5–1.5, 1–3 h and 200–600 µm, respectively. In this work, petroleum coke desulfurization conditions using solid KOH have been studied.

Graphitized petroleum coke recarburizer is a process of treating petroleum coke into high temperature by graphite. This process is the process of energizing petroleum coke and then calcining at a high temperature of 3000 degrees, so that the carbon molecular form of petroleum coke is changed from irregular arrangement to hexagonal uniformity.

refinery personnel with the delayed coking operation, delayed coking unit hardware, types of coke that can be produced, coke formation models, and the uses of petroleum coke. Also, by discussing some of the delayed coking process problems encountered in the industry, we hope to encourage new advances, solutions, and improvements for the future.

petroleum coke is used in the energy sector (mostly in North Petroleum coke (petcoke) is a by-product produced from heavy America). In the past, petroleum coke has often been burned as fuel crude oil residues by thermal cracking processes – delayed or fluid in boilers for heat and power production.

Amixing of 1:3 ratios of petroleum coke and charcoal gives the maximum reduction efficiency. The optimum time for the reduction was found to be 15min, and the optimum temperature was 900°C. The reduction follows first order kinetics and the rate of the reaction was 0.22/min. Key words: Ilmenite, Reduction process, Petroleum coke, Charcoal. 1.

reduce iron ore to iron. Over 90 percent of the total coke production is dedicated to blast furnace operations. Foundry coke comprises most of the balance and is used by foundries in furnaces for melting metal and in the preparation of molds. Foundry coke production uses a different blend of coking coals,

Vibrated Bulk Density (VBD) of calcined petroleum coke is widely utilized as one measure of quality and is useful for quantifying binder demand in the anode production process of the aluminum reduction industry. ASTM D 4292-10 is one of the methods used widely by the carbon and aluminum reduction industries to measure VBD.

Researchers often use calcined coke and anode core properties to predict carbon consumption in aluminum reduction cells. This study compared laboratory analysis data and production data from 1992 through 1995 at RMC's Lake Charles Carbon Company and Baie Comeau Reduction Plant.
