Option 2: Calcination process is a thermal upgrading of Green Petroleum Coke (GPC). This process carried out in the rotary kiln to produce Calcined petroleum coke (CPC) which will be used in green anode production in carbon plant. Explain: 1- Calcination process in the rotary kiln and why it is important. 2- The different types of heat transfer in the rotary kiln. 3- The main factors affect the

    Aug 15, 2013 Aug 15, 2013 During the calcination process, the GPC is heated to remove the volatiles and sulfur to produce purified calcined coke, which is used in the production of graphite, electrodes, metal carburizers, and other carbon products. Currently, more than 80% of calcined coke is produced in rotary kilns or rotary hearth furnaces. These technologies provide partial heat utilization

    Table 1 shows the results of a TDS trial in a rotary kiln with green petroleum coke (GPC) containing 4.6% S. The S loss under normal calcining conditions is 9–14% and it is important to note that this is not caused by TDS [1]. At higher calcining temperatures, the S loss increases to 30 and 47% due to TDS. This is accompanied by a drop in vibrated

    Calcined coke is the best material for making carbon anodes for smelting of alumina to aluminum. Petroleum coke is usually calcined in a gas-fired 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 strength, and electrical conductivity of the material

    In 2011, Rain Carbon started to experiment with the agglomeration of green petroleum coke (GPC) fines as a way to improve calcining economics. When a rotary kiln is used for calcining, around 10% of the finest particle size GPC becomes entrained in the counter-current flue gas stream inside the kiln

    Dec 20, 2014 The first rotary kiln for calcining GPC was used at Great Lakes Carbon in 1935,2 although rotary kilns had been used in the cement industry prior to that. Rotary kilns for CPC production are steel shells lined with high-temperature refractory brick; kilns can measure 30–85 m in length and 2.4–4.4 m in diameter

    The volatile combustible matter of green coke ranges from as low as 6 to as high as 20 wt%, so for all these applications, the raw petroleum coke should be thermally upgraded prior to its use in a process called calcination to obtain CPC. Pet-coke calcining is therefore the process whereby “green coke” or raw petroleum coke is thermally
