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. Petroleum coke just one of the many. Petroleum coke is not a new product and has been produced since the 1930s.

But existing coal mill was capable of giving 5% max on 90 micron (design was 15% on 90 micron for Indian coal which is softer). Pet coke is very hard to grind (Hard grove Index 35-45) against 60-65 HGI (Hardgrove Index) in normal coal. Therefore without any modification, it was not possible to get targeted value of fineness in pet coke.

In the process, a significant portion of the feed (~15% of volume) is converted into elemental carbon called petroleum coke. Refiners separate the coke from the other coker products and sell it as a product. The primary end use for pet coke is as a solid fuel, used as a substitute for coal in furnaces and boilers.

The Raymond® Bowl Mill is widely used throughout the cement and lime industries for grinding coal and petroleum coke to be used as fuel to fire kilns or flash calciners on preheater-type kilns. In operation, raw fuel is fed to the bowl mill by means of a weigh feeder. The metered fuel enters the mill through a rotary vane-type feeder or

Coal Grinding. To achieve good combustion and satisfactory flame formation, coal needs to be dried and ground to a proper degree of dryness and fineness. Drying of moisture in coal is achieved normally by ducting part of the kiln exhaust gas through the mill with inlet temperatures of up to 300°C. Inert kiln exhaust gases with oxygen content ...

Three main types of coke are produced from coking coals (Coal Technology, 2017) as follows:Metallurgical coke is produced in coke ovens and is mainly used for the iron ore reduction in blast furnaces (BFs). It is also consumed in blast and electric furnaces for ferroalloy production and for the reduction of …

India is the world's biggest consumer of petroleum coke, better known as petcoke, a dark solid carbon material that emits 11 per cent more greenhouse gas than coal, according to studies.

The ladles then carry the molten steel to the steel mill's caster, which makes new products from the recycled scrap. ... 'Pet coke' is a by-product of the oil refining process, while coal-based ...

The high-temperature CO2 gas reacts with the carbon in the coke to form CO, and the CO further reduces the iron ore to form molten iron. Carbon supply: The carbon content of pig iron is about 4%, all from blast furnace coke, accounting for 7%-9% of coke carbon content. Heating: The combustion of coke, injected fuel and external hot air …

A policy regarding petcoke and furnace oil use has been framed with a list of approved fuels and timelines for compliance. Petcoke will be allowed in Cement Plants/ Lime Kilns, Calcium carbide and Gasification use. However, furnace Oil is allowed in units with conditions of 90 % scrubbing and removal of SO 2. Manipur.

Fine coal air mixture leaves the mill and enters the fuel piping system. Tramp iron pieces which are not required to grind, leave the Bowl due to centrifugal force and are removed through the reject removal system. Bowl Mill Nomenclature / Designation Suction type mills are designated as XRS whereas pressurized mills as XRP and HP.

1. The hot air dries the coal. 2. The hot air is used for transportation of the recirculating coal within the mill and also for. transporting the coal from the pulverizer to the furnace. As the coal is continuously reduced in size, the smaller/lighter particles are swept from the bowl by the hot air. Hot air (and cool tempering air) is provided ...

The iron and steel industry uses petcoke as a feedstock – blending with coking coal during the coke making process. 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 ...

Coke is used as a fuel and a reducing agent in melting iron ore. It is produced by baking coal until it becomes carbon by burning off impurities without burning up the coal itself. When coke is consumed it generates intense heat but little smoke, making it ideal for smelting iron and steel. Prior to the 1880's, steel was produced using …

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. High grade petcok…See more on petro-online

People also askCan pet coke be used in cement plant?Pet coke has been used as an alternative fuel, over the last few years, in a number of cement plants. The cement plant in our case is not been designed for pet coke, we used coal in all system. Hence, we try to use pet coke in main burner, without changing coal in precalciner, to evaluate the advantages and disadvantages, in our plant.

whatispipingWhat is the difference between pet coke and coal?Fix carbon varies from 80 – 92 %. Pet coke has a lower ash content compared to Coal, about 0.3 – 0.5 %. It is non-hygroscopic in nature. Moisture is typically less than 1.5 %. Sulphur content of pet coke, range from 6.0 % to 7.5 % as compared to typical levels of 0.5 % to 1.0 % in coals. Pet coke is relatively finer compared to coal.

Global steel production is dependent on coal. 70% of the steel produced today uses coal. Metallurgical coal – or coking coal – is a vital ingredient in the steel making process. World crude steel production was 1.4 billion tonnes in 2010. Around 721 million tonnes of coking coal was used in the production of steel.

Coal, lignite or petcoke are ground in the Pfeiffer vertical mill by using hot gases from a hot gas generator. The grinding plant can be inerted. The raw coal is dried while being ground in the mill even if feed moisture exceeds 25%. The feed size that can be handled is up to 100 mm, making two-step pre-crushing unnecessary.
