Since the ban has been imposed recently, its impact is yet to be assessed. Various categories of industries such as cement, thermal power plant,
Dec 20, 2014· 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. 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.
Emissions of sulfur dioxide after burning the coal / pet coke in boiler causes serve damage not only to the environment, historical monuments like TajMahal 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
Jun 23, 2013· Sulphur content of the BF coke has also got its affect on the BF productivity. A decrease of sulphur content of coke by 0.1 % improves the BF productivity by 0.7 % to 1.2 %. Fuel (pulverized coal/ natural gas/ coke oven gas/oil/coal tar) injected at the tuyere level is normally accompanied by oxygen enrichment of the hot air blast.
The sulphur content of HSFO is typically 2.5-3.0 %S which if refined to 0.5% S, would equate to the removal of 3.0-3.8 million tonnes of sulphur although CRU this scenario to be achievable in 2020. The near term change in sulphur supply will be dependent on investment in refining capacity, spare capacity at existing refineries and changes in ...

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: 32.065 gm/mol. Formula: S. Melting point ...
May 01, 1989· Here, the effect of calcium to sulphur molar ratio on the retention of sulphur dioxide is shown to be similar to that observed for combustion tests in a FUEL,1989, Vol 68, May 583 Fluidized bed combustion of petroleum coke: A.

• Injection of absorbents such as hydrated lime (Ca(OH) 2), calcium oxide (CaO), or fly ashes with high CaO content into the exhaust gas before filters; • Use of wet or dry scrubber s.8 SO 2 emissions in lime manufacturing are generally lower than in cement because of the lower sulfur content of raw materials. Techniques to limit SO

Oct 11, 2013· petcoke as fuel for cement production why petcoke high calorific value > 8,000 kcal/kg (3500-4500 kcal/kg conventional), low ash content & low volatile matter (but high sulphur content, up to 7%) resource conservation thru production of higher grade cement or utilisation of marginal & low grade raw materials saving in transport cost due to ...
12.2 Coke Production 12.2.1 General ... volatile coals that are generally low in sulfur and ash. Blending is required to control the properties of the ... moisture content, rate of underfiring, and the desired properties of the coke. When demand for coke is low, coking times can be extended to 24 hours for blast furnace coke and ...
Sulfur (ASTM D4239, ISO 351, AS1038.6) It is important to measure the sulfur content in coal samples to evaluate the potential sulfur emissions from coal combustion, or for contract specifications purposes. SGS has the facilities and the know-how to provide you with timely accurate results. Calorific Value (ASTM D5865, ISO 1928, AS1038.5)
"Petroleum coke prices have peaked and will continue to slide from their recent highs (of about $23.75/tonne on the spot market for 4% sulfur coke) through 2005," said the study.
The industry only uses low-sulphur (<2.5 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.
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 by-product 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 ...
– 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 5-7 °F for 1% decrease in VCM – Increase heater outlet 1-2 °F for each hour reduction in coking cycle time
Jul 11, 2015· Limitations of use of Pet-coke A few of the limitations of the use of pet-coke are as under mentioned:- * Since the sulphur content in the pet-coke is high, the quantity of its use is limited by the molar ratio of oxides of alkalies to sulphur in hot meal entering the kiln which must be .
Sep 14, 2015· The amount of fresh lime injection is not limited by flue gas temperature thus allowing greater SO 2 scrubbing performance over a wider range of fuel sulfur content.
Petroleum coke (petcoke) is a black colored solid composed primarily of carbon, and may contain limited amounts of elemental forms of sulfur, metals and non-volatile inorganic compounds. Petcoke is the co-product of several processes used in petroleum refining to upgrade "residuum" into gasoline and middle distillate-range fuels.
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.
