Petroleum coke calcining emissions. Process description. In the aluminium industry, petroleum coke is typically calcined in rotary kilns at high temperatures. After it has been crushed and screened, the calcined coke is usually stored until it is fed into mixers to produce anodes.
The main function of a pyroscrubber in petroleum coke calcining process is to oxidize the carbonaceous contents, including hydrocarbon volatiles, of the exhaust gas from the calcination kiln, so as to leave no more than small traces of unburned volatiles, solid carbon, ashes, or emissions ( CO, NOx and SOx) in the flue gas finally discharged.
Calcined petroleum coke (CPC) is created from green petroleum coke (GPC), a byproduct of refining crude oil. While CPC can be created using a number of processes including rotary kiln, hearth and vertical shaft technologies the hightemperature conversion from green coke to calcined coke alters the material in key three ways:
The following documents and tables contain the EPA approved rules and regulations for the South Coast Air Quality Management District (AQMD) portion of the California State Implementation Plan (SIP).
Calcined Petroleum Coke is a critical ingredient in the production of aluminum. It is created by placing high quality raw "green" petroleum coke into rotary kilns, where it is heated to temperatures between 1200 to 1350 degrees C (2192 to 2460 F).
Dec 20, 2014· The History and Future Challenges of Calcined Petroleum Coke Production and Use in Aluminum Smelting. ... This was followed in 1935 by the development of the rotary kiln calcining process, which is the most commonly used technology in the Western world. ... Early calcining of petroleum coke used both electric and gas fired vertical calciners, 2 ...
The oldest and newest petroleum coke calciners employ rotary kilns to thermally upgrade green coke, thus rendering it suitable for use by the amorphous carbon and graphite industries. In response to environmental pressures and rising fuel costs, modern coke calcining facilities are much cleaner and much more thermally efficient.

B. Calcined petroleum coke . Calcined petroleum coke (CPC) is the product from . calcining. petroleum coke. This coke is the product of the . Coker unit in a crude oil refinery. The calcined petroleum coke is used to make anodes for the aluminum, steel and titanium smelting industry. Calcined petroleum coke is shown in figure 2.
How it works. Coke calcining plants can be located in oil refineries, captive plants in aluminum smelters or merchant plants. Rotary Kiln The petroleum green coke is fed into a refractory lined rotary kiln where the volatiles are driven off during the calcining process in an oxygen deficient atmosphere.

is operating successfully on a petroleum coke calcining kiln. Acceptance tests and continuous data logging demonstrate sulfur dioxide removal efficiencies in excess of 90%, and participate emissions less than gr/acf. The system consists of a spray dryer, fabric filter and auxiliaries which are designed to process up to 205,000 acfm gas flow.
Petroleum Coke Calcining Rotary Kiln Petroleum coke calcining rotary kiln uses the volatile component emitted in the roast process of the petroleum coke Active Lime . Inquiry; Lime Rotary Kiln Great Wall. Lime rotary kiln is the main equipment of lime production line It is widely used for many industries like metallurgy chemical industry.
A pyroscrubber is a furnace used in the petroleum coke calcining industry to recover energy from the carbonaceous contents, including char dust and hydrocarbon volatiles of the exhaust gas from the calcination kiln.
The Los Angeles refinery manufactures cleanerburning California Air Resources Board (CARB) gasoline and CARB diesel fuel, as well as conventional gasoline, distillates, petroleum coke, anodegrade coke, chemicalgrade propylene, fuelgrade coke, heavy fuel oil and propane.
Petroleum coke has between % and % nitrogen (N) compared with about to % N for residual fuel oil. Thus, there would appear to be significant potential for fuel NOx formation from petroleum coke combustion. However, observed levels of NOx emissions from burning petroleum coke in lime kilns
Calcined coke is the best material for making carbon anodes for smelting of alumina to aluminum. Petroleum coke is usually calcined in a gasfired rotary kiln or rotary hearth at high temperatures, around 1200 to 1450 °C, to remove moisture, drive off volatile matters, increase the density of the coke, increase physical
Cokecalcining plants receive green petroleum coke from oil refineries. The green coke is blended and fed into rotary kilns operating up to 2800°F under a reducing condition. The material exits the rotary kiln as calcined coke with a correct crystalline structure and electrical conductivity properties.
¾ SO2 emission depending on S content in coke ¾ NOx lower than rotary kiln as no incinerator ¾ CO2 emission 40 % lower than rotary kiln ¾ as often used by the Heat recuperation possible as steam, power generation or sea water desalination. Plant Lay out A 500''000 tpy plant requires a total surface of 240''000 m2. The 16 kilns are ...
Petroleum coke, abbreviated coke or petcoke, is a final carbonrich solid material that derives from oil refining, and is one type of the group of fuels referred to as is the coke that, in particular, derives from a final cracking process—a thermobased chemical engineering process that splits long chain hydrocarbons of petroleum into shorter chains—that takes place in units ...
914301 Emission Limit: The owner/operator of a petroleum coke calcining operation subject to this rule shall comply with all of the following: Effective January 1, 2019, operate at least one Petroleum Coke Calcining Kiln subject to this standard such that the Petroleum Coke Calcining Kiln does not emit SO 2
petroleum coke calcining plant in the town of Rodeo. The draft rule would apply generally to petroleum coke plants; however, Phillips 66 currently operates the only such plant within the jurisdiction of the Air District. This facility, commonly referred to as the "Carbon Plant," operates two rotary kilns in its calcining operation.
