A = 0%). The sieve with hole size "k" is the hypothetical sieve through which no coke will pass (k=0mm, K=). Coke Reactivity Index (CRI) and Coke Strength after Reaction (CSR) When coke descends in the blast furnace, it is subjected to reaction with countercurrent CO 2 and abrasion. These concurrent processes weaken the coke and chemically ...
A. A Boateng, in Rotary Kilns (Second Edition), 2016. Abstract. Petroleum coke is a byproduct of the coker process in the oil industry. In its raw form, it is also called "green coke" or green petroleum coke. Calcined petroleum coke is an important industrial commodity that links the oil and the metallurgical industries as it provides a source of carbon for various metallurgical ...
Sulphur is a constituents of fuel found from its ultimate analy sis about 1% to 8% as per quality of fuel. Basically Pet coke having higher sulfur percentage which is a byproduct of Pe troleum refinery. Sulfur reacts with oxygen to produce sulfur dioxide (SO₂) sulfur xide (SO₃). Molar mass: gm/mol. Formula: S. Melting point ...
Jul 01, 1990· The sulfur content of petroleum coke has steadily increased in recent years, and forecasts show levels will rise even further. This increase in sulfur content comes at a time when environmental awareness is at a peak, and regulatory restrictions are likely to place limits on the amount of sulfur permitted. Fortunately for aluminum smelters, several methods of reducing the sulfur content .

Emissions of sulfur dioxide after burning the coal / pet coke in boiler causes serve damage not only to the environment, historical monuments like TajMal but also to the human health. Because of the ecological and human health impacts of sulfur dioxide regulatory standards have been set to bring down the SO 2 emission into the atmosphere. This
Sep 09, 2013· C2S which has sulphur incorporated into its crystal structure is stabilised and therefore has a reduced tendency to react with additional CaO to form C3S. This results in an increase in the quantity of C2S and a corresponding reduction in the C3S content of the final clinker, despite there being sufficient free lime to convert the C2S into C3S.
– Target 12% Max, fuel coke 9% to 10% – 14% VCM is very high; Coke will be soft • Increases green coke hydrogen content • Rules of thumb for control in fuel coke – Increase heater outlet 57 °F for 1% decrease in VCM – Increase heater outlet 12 °F for each hour reduction in coking cycle time
Green Petroleum Coke is to be Calcined after extraction. Calcining is done in a rotary kiln to temperatures of 1600oC. CPC has Fixed Carbon Content of 99% +/ and Volatile Content %. Sulphur content varies depending on the crude used to make the Green Petroleum Coke .

Dec 20, 2014· Calcined petroleum coke is used for the production of carbon anodes in the HallHéroult aluminum smelting process due to a combination of low impurity levels, ready availability, and relatively low cost. This article provides a review of the history and use of calcined petroleum coke for anode production and describes the different calcining technologies used by the industry.
The industry only uses lowsulphur (< per cent) imported petcoke with a blending limit of 15 per cent as the presence of sulphur is detrimental to steel quality. Increase in the sulphur content would require additional volumes of limestone to remove the sulphur as slag. It will further increase the coke requirement per tonne of crude steel.

Petroleum coke (petcoke) is a black colored solid composed primarily of carbon, and may contain limited amounts of elemental forms of sulfur, metals and nonvolatile inorganic compounds. Petcoke is the coproduct of several processes used in petroleum refining to upgrade "residuum" into gasoline and middle distillaterange fuels.
