What is the difference between Met coke and pet coke?

Petcoke Compared to Metallurgical Coke and Coal

Petcoke has a significantly high heating value compared to metallurgical coke (metcoke) and bituminous coals (see Table 2). The higher heating value comes at the cost of higher sulfur and nitrogen content, however.

What does coke PET mean?

Petroleum coke (often abbreviated 'pet coke' or 'petcoke') is a carbonaceous solid delivered from oil refinery coker units or other cracking processes.

What is difference between pet coke and coal?

Petcoke is over 80% carbon and emits 5% to 10% more carbon dioxide (CO₂) than coal on a per-unit-of-energy basis when it is burned. As petcoke has a higher energy content, petcoke emits between 30 and 80 percent more CO₂ than coal per unit of weight.

Is petcoke better than coal?

Petcoke is an extremely stable fuel which means there is little risk of combustion during transportation, but due to its high carbon content when it does combust it releases up to 10% more CO2 per unit of energy that normal coal.

What is green pet coke?

Green petroleum coke is obtained from processing liquid fractions in Delayed Coking Units (UCR). It is a material with high fixed carbon content comprising hydrocarbons and low levels of inorganic compounds.

Coal vs Coke |Fast differences and Comparison|

What is Sponge coke used for?

Sponge coke is used as solid fuel, and manufacturing anodes for aluminum production, if its sulfur and metal concentrations are sufficiently low.

What is needle coke?

Needle cokes are used as a primary material for graphite electrodes in electric furnace. Coal-based needle coke is produced from coal tar that appears during coke production.

Is petcoke cheaper than coal?

While pet coke costs ₹12,500 per tonne, the cost of coal is ₹10,500 per tonne.

What is petcoke made of?

Petroleum coke, or petcoke, is a product produced from all types of oil (light/heavy crudes) during the oil refining process. Many different products are extracted from a barrel of crude oil in addition to gasoline, diesel and jet fuels.

What is the price of petcoke?

Petcoke prices are finally moving down but this is slow based on indexation. The price of 6.5 per cent sulphur petcoke USGC FOB declined from US$154.00 to US$148.00 while the CFR ARA price fell from US$188.00 to US$176.50.

What is the difference between coking and non coking coal?

Noncoking coals have higher ash content and are typically used in thermal power plants as steam coals. Coking coal is the type of coal which on heating in the absence of air undergoes a transformation into a plastic state, swells, and then solidifies to form coke.

What is nut coke?

Nut Coke means coke otherwise meeting the quality specifications in Schedule A and of a size equal to or greater than 3/8 inch and less than 3/4 inch.

What can petroleum coke be used for satisfactory?

Used for crafting. A carbon-rich material distilled from Heavy Oil Residue. Used as a less efficient coal replacement or for aluminum refinement.

Is petcoke toxic?

Although the number of reports and population sizes were small, the overall conclusion from these studies is that petcoke is not carcinogenic via inhalation or dermal exposure, there is low risk of developmental toxicity but some risk of reproductive effects, and that the primary health effect via inhalation is ...

Is petcoke banned in India?

The Supreme Court has banned the use of petroleum coke or petcoke — solid-carbon, coal-like material which results from oil refining — and furnace oil in the National Capital Region (NCR) and suggested that similar steps be taken in other States.

Is petcoke used as a fuel?

One important product produced by refineries is something called petroleum coke, or “petcoke.” Petcoke is used as a fuel and as a source of carbon for industrial processes.

What is graphite coke?

Synthetic graphite is a manufactured product made by high-temperature treatment of amorphous carbon materials. In the United States, the primary feedstock used for making synthetic graphite is calcined petroleum coke and coal tar pitch, both of which are composed of highly graphitizable forms of carbon.

What is graphite petroleum coke?

(1) Graphite Petroleum Coke is produced in graphitization furnace at about 3000 ℃. (2) Calcined petroleum coke is produced in a forge furnace at a temperature of more than 1500 ℃. Third: fixed carbon content is different. (1) The fixed carbon content of graphitized carburizer is about 98%, and the highest is 99%.

Is petroleum coke worth satisfactory?

Petroleum coke is at first slightly better than fuel made from heavy oil residue, but when you unlock diluted fuel, it becomes almost three times more efficient than petrol coke.

How is petcoke used in cement industry?

In the cement industry, petcoke is used as an energy source. Some cement plants use 100 per cent petcoke instead of coal (ACC Ltd 2009), where the SO2 released from the thermal decomposition is absorbed by the limestone.

Is petcoke flammable?

Petcoke is generally stable under normal conditions; however, the substance has the potential to become flammable or explosive.

What is petcoke coal?

Petcoke is a direct replacement of coal as a fuel but has higher calorific value (>7800Kcal/Kg as compared to 3500-4500 Kcal/Kg for coal). Petcoke is hydrophobic as compared to coal which is hydrophilic, thereby having edge during rainy season.

Why coke is used in blast furnace not coal?

The single most important factor is strength ( mechanical compressive ); coal is heated to make coke, the resulting coke is stronger than the original coal. Also, coke helps to make the charge of iron oxides and limestone more porous to permit gas flow up and droplets of liquid iron and slag down.

What is the purpose of coke in the blast furnace?

Blast furnace ironmaking makes use of coke as the major source for both energy and reduction of iron oxides. In the blast furnace process, coke has multifunctions and plays an important role as reductant, burden support, and fuel.

Which is the best grade of coal?

Anthracite: The highest rank of coal. It is a hard, brittle, and black lustrous coal, often referred to as hard coal, containing a high percentage of fixed carbon and a low percentage of volatile matter.
