Coke fines are the single largest type of fines in the delayed coker. Coke fines can be a problem in both the primary process operations and in the ancillary operations such as coke cutting and coke handling. When the coke drums are being filled, coke fines can be entrained in the drum overhead into the fractionator due to high vapor velocities ...

2024年7月10日 · Coke fine refers to the small-sized particles or fine granules of coke, a carbon-rich material derived from coal or petroleum. These fine particles are typically produced as a by-product during the crushing, screening, and handling of larger coke pieces.

2013年1月6日 · Coke fines are the single largest type in a delayed coker. They can be a problem both in primary process operations and in ancillary operations such as coke cutting and coke handling.

2023年12月11日 · Involvement of petroleum coke fines and coking additives in coal charges makes it possible to significantly improve the performance properties of blast furnace coke. The available and prospective caking additive production technologies using heavy oil residues are studied and compared.

2023年6月19日 · By performing settlement calculations, we can determine the dimensions and configuration of the fines maze that would be effective in separating fines from the coke. I would recommend to explore engineering guidelines related to the sizing of fines mazes, which may include evaluating factors such as flow rates, particle characteristics, and ...

2013年12月1日 · The aims of this work are to study coal, char and coke structures by XRD and to quantify carbonaceous components (char and coke fines) in the flue dust BF samples at all coke and PCI BF operations through the use of the XRD technique and ultimate analysis.

1996年5月1日 · The agglomeration process is of broad potential use in revaluing fine-sized petroleum coke wastes and waste products known as impalpable fines. These materials were agglomerated in a disc pelletizer with binding agents to obtain pellets with high carbon content, good reactivity and good consolidation in hot and cold environments.

There seems to be less demand for coke fines than for other types of coke. While coke fines may be easier to burn as a fuel, their use for other applications is not always to be recommended. Furthermore, the creation of coke dust, associated with the presence of coke fines, is a major cause of environmental problems. It results also in

A great deal of attention was given to the problem of effective utilization of the petroleum coke, particularly the below 25 mm fines, which due to their high sulfur content (3.6 to 4.2%) and the difficulty of removing the sulfur have not found an efficient use. The results of this investigation are briefly summarized. (JMT) | OSTI.GOV

2013年2月3日 · HKGO filter systems remove coke fines from the heavy gasoil stream for feed to a hydrotreater or other downstream unit. The most common filter systems use mesh or edge disk filters (wedge...
