Stated succinctly, coke is the “carbonization product of high-boiling hydrocarbon fractions obtained in petroleum processing (heavy residues).” Petcoke is also produced in the production of synthetic crude oil (syncrude) from bitumen extracted from Canada’s oil sands and from Venezuela’s Orinoco oil sands.
Is petroleum coke hazardous?
First, the MDEQ most certainly did find that there are health threats from petroleum coke, stating that “Human exposure to fine particulate matter (PM) emissions from petcoke storage piles, at sufficiently high concentrations and durations of exposure, could cause respiratory and cardiovascular effects characteristic …
Where does petroleum coke come from?
Petcoke is a byproduct created when bitumen found in tar sands, like those in Alberta, Canada, is refined into crude oil. Bitumen contains a higher number of carbon atoms than regular oil and it’s these atoms, extracted from large hydrocarbon molecules using heat, that go on to form petcoke.
What is petroleum coke function?
Calcined petroleum coke is used for the production of carbon anodes in the Hall-Héroult aluminum smelting process due to a combination of low impurity levels, ready availability, and relatively low cost.
What is Coke in the refining process?
Petroleum coke is a byproduct of the oil refining process. As refineries worldwide seek to operate more efficiently and extract more gasoline and other high value fuels from each barrel of crude oil, a solid carbon material known as petcoke is produced.
What is green pet coke?
It is an abbreviated form for ‘petroleum coke’ that is made available in different types as well as in grade options. … Some of the other varieties it can be made available by us include calcined pet coke and raw pet coke. Fill the quantity to get latest price!
Why Coke is not used as a fuel?
The term means a product similar to coal and mined the same way. Coal is cheaper and that is why it is used more often. … Coke is cleaner and other methods should be looked into before coal and oil run out.
What is shot coke?
Shot coke is an undesirable grade of pet coke sometimes produced from a delayed coker. The irregular structure of shot coke makes it difficult to handle and unacceptable for any specialty coke uses (relative to the more desirable sponge coke).
What is pitch coke?
Pitch coke is produced from coal tar that appears during coke production. Pitch cokes are an essential raw material for building production equipment for semiconductor or solar array panel. It is also used as a raw material for the anode in aluminum smelting.
What is needle coke?
Needle coke, also called acicular coke, is a highly crystalline petroleum coke used in the production of electrodes for the steel and aluminium industries and is particularly valuable because the electrodes must be replaced regularly.
What’s the difference between coke and coal?
What is the difference between coal and coke fuel? Coal is a shiny, black fossil fuel that contains impurities, emits smoke when burned, and produces less heat than coke. Coke is a dull, black byproduct of coal that burns hotter and cleaner.
What is coke ash?
Coke is a grey, hard, and porous fuel with a high carbon content and few impurities, made by heating coal or oil in the absence of air—a destructive distillation process. It is an important industrial product, used mainly in iron ore smelting, but also as a fuel in stoves and forges when air pollution is a concern.
Is petcoke cheaper than coal?
While pet coke costs ₹12,500 per tonne, the cost of coal is ₹10,500 per tonne. However, 70% more coal is used than coke for the same output,” Arora said.
What causes coking?
Studies have shown that coking occurs when fuels or oils are exposed to temperatures over 200 C, and increases significantly at temperatures over 400 C. Frequently, exposure to high temperature occurs after the engine or process is shut down, when there is no coolant flow to carry away excess heat.
What is non coking coal?
Non Coking Coal does not have any caking properties and it is mainly used as thermal coal for power generation. It has a higher ash content and also used in industries like cement, fertilizer, glass, ceramic, paper, chemical and brick manufacturing.
What is metallurgical coke?
Metallurgical coke is produced by destructive distillation of coal in coke ovens. Prepared coal is “coked”, or heated in an oxygen-free atmosphere until all volatile components in the coal evaporate. The material remaining is called coke.
