Oil refinement produces petroleum coke. It is highly dense and contains a lot of carbon. It also contains some hydrogen, oxygen nitrogen, sulfur, and metal elements. It's an excellent fuel to generate electricity. It is a very efficient and clean fuel that can compete with fossil fuels. It is used for making graphite electrodes, which are essential materials in the aluminum and steel industries. Natural graphite can be substituted with this product due to its low sulfur, nitrogen and ash content. It is also a good conductor, has high thermal stability and is pure.
In comparison with coal, petcoke contains lower levels of volatile matter and sulfide. In the steelmaking process, it is used to replace certain raw materials like iron ore and coke. However, it is not suitable for all steel making processes. To ensure sustainable growth, it is crucial to maintain a balance between supply and demand for petcoke.
In order to refine petroleum, coke, pyrolysis is required. This produces a solid carbon rich product. The coke will then be calcined into a fuel or carbon source. The calcination method requires high temperatures and a rotary oven or vertical shaft furnace. It also removes all volatile materials from the coke. This increases the carbon content and makes it easier to use in industrial applications.
Sponge coke is a form of petroleum coke that has an obvious acicular texture. The coke is produced through pyrolysis of heavy residues on a fluidized bed. It's considered a better type of petcoke than other petroleum coke types because it has more fixed carbon. It is used primarily to produce anodes for the aluminum industry, because it has good electrical conductivity and thermal shock resistance.
There are also other methods for producing petroleum-coke, such as fluid and flexible coking. These processes allow for more automation and are more cost-effective at the beginning. The coking processes are also evolving. Digital twins and artificial intelligence can be used to optimize performance of plants and minimize their energy consumption.
The melter-gasifier has three sections, the lower section A and the central section B. The lower A section collects molten metals and liquid slags that may contain sulfur residues from the combustion coke. A wall 2 of lower section A contains a tapping aperture 10 for the melting melt. A layer of slag is present above the tapped melt 11. The lower section of A is heated up to superheated temperatures. The slag and metallic melt are separated by separating the slag. Coke is abrasive and requires abrasion resistance liners to be installed in the feed tube, interior drumshell, and lifting flights. In many cases, the internal lifting flights are fabricated from hardwearing abrasion resistant (AR) steel. Wear plates made of abrasion-resistant (AR) steel are often added to the system as an extra layer of protection.
