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.
Mar 16, 2013· The pressure and temperature in shaft furnace in HYL process is 5-6 bars and 800-850 deg C. The same in Midrex process is 1-1.5 bar and 800-850 deg. C. In a coal based plant the reactor for the reduction reaction is a inclined horizontal rotary kiln. In this kiln both coal and the iron ore feed material is charged from the same end of the kiln.
Due to the process temperature you can earn more condensable oils or permanent gases from the pyrolysis process. Due to the target you call the same process torrefaction, pyrolysis, carbonisation or gasification. There is a smooth transition, but all processes can be done in the (nearly) same rotary kiln!

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 ...

ding needle, sponge, shot, fluid or tar pitch green cokes. The rotary kiln is also able to optimize the coke calcining operating parameters, be it residence time, temperature gradient, and heat up rate, all of which impact product quality. Product quality KVS' coke calcining systems can produce a quality product specifica-
Dec 20, 2014· The design concept and calcining process of rotary hearth calciners have been described previously. 16 The coke moves slowly from the outside perimeter of the rotary hearth kiln guided by rabbles toward the inner soak zone before exiting the hearth and being cooled with water in a rotating unit similar to the one described for the rotary kiln.
The fuel for this may be gas, oil, pulverized petroleum coke or pulverized coal. Construction. The basic components of a rotary kiln are the shell, the refractory lining, support tyres (riding rings) and rollers, drive gear and internal heat exchangers. History. The rotary kiln was invented in 1873 by Frederick Ransome. Kiln shell

rotary coal burner . Rotary Kiln For Coke Fuel With Coal Burner cost Tanzania, In industrial kiln the cement rotary kiln is the earliest equipment using coal as fuel but the pulverized coal burners for cement rotary kiln was lack of indepth research therefore pulverized coal burner rotary kiln used for rotary kiln has been very poor single duct pulverized coal burner.
After coal comes out of the ground, it typically goes on a conveyor belt to a preparation plant that is located at the mining site. The plant cleans and processes coal to remove dirt, rock, ash, sulfur, increasing the heating value of the coal. During this coal processing, the used industrial equipment can be called coal processing equipments.
Rotary Dryers for Coke. Like many industries, rotary dryers are the industrial drying system of choice when it comes to drying coke. Rotary dryers are known for their robust build, high throughput, and ability to accept variance in feedstock – all characteristics that lend well to handling coke.
The chemistry of production is not dissimilar to that from coal, and similarly, the degree of refinement towards pure carbon depends upon the economics of the end-use. Calcined petroleum coke, produced in a rotary kiln, is used to make anodes for electrochemical furnaces .
phases. The present paper considers the use of the rotary kiln for the pyrolysis of coal to produce high reactivity coke for electrometallurgical applications. The coal is introduced at one end of the furnace in the form of 1 to 2 cm diameter grains and flows
