What is met coke?
“Met Coke” or “Metallurgical coke” is a carbon residual-material made or manufactured by the “destructive distillation” or “carbonization” of various blends of bituminous coal; a type of coal which is a soft, medium grade containing a high percentage of volatile components.
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.
How is met coke made?
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.
What is met coal used for?
Metallurgical coal is an essential ingredient in the production of steel, one of the most widely used building materials on earth. It takes around 770 kilograms of coal to make one ton of steel with approximately 70 per cent of global steel produced in basic oxygen blast furnaces.
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 petcoke coal?
It is abbreviated as Coke or Petcoke, and is a carbon-rich solid material derived from final cracking process — a thermo-based chemical engineering process that splits long chain hydrocarbons of petroleum into shorter chains— that takes place in coker units.
Is met coal better than thermal coal?
Met coal typically contains more carbon, less ash and less moisture than thermal coal, which is used for electricity generation.
Why is pet coke banned?
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.
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 graphite petroleum coke?
Calcined Petroleum Coke is extensively used for melting purpose of Alumina in Aluminium industry, as a carbon raiser while making Special High Carbon Steel in Foundries, as a conductive backfill in ground Electrode station and in manufacture of various Carbon and Graphite Products.
