Shaft kiln, just as its name implies, is a kiln with erected shape. Shaft kiln with modern new technology has environmental protection function, energy-saving function, high mechanization, and high automaticity. It also has the ability to turn waste into wealth. Therefore, it can make full use of cheap energy, especially the pollution-carry gas ...
Raw Petroleum Coke (RPC) received from the Refinery is sized and fed into a Kiln which may be rotary or Vertical shaft kiln. The coke gradually moves towards the lower end of the kiln and during its movement down the Kiln all moisture and volatile matters present in the RPC are driven off. It is a exothermic process with the burning of ...

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.

A shaft calciner has multiple vertical refractory shafts surrounded by flue but the design will of calcined petroleum coke from the company39s new calciner, vertical shaft calciner design petroleum coke calcination of petroleum coke in vertical shaft kiln shaft calciner is widely applied in China for diesel oil .
The shaft refers to a vertical vessel where the calcining takes place. Because of the weight of the bed of material in the shaft, there are limits on the size and strength of the type of limestone that can be calcined. Vertical kilns work on a batch-type system rather than continuous feed, and the upper kiln area is used for preheating.
The present invention is directed to a method for calcining green petroleum coke and more particularly for calcining green petroleum coke utilizing a shaft calciner which will reduce product dusting problems or with a rotary kiln calciner to significantly improve recovery and produce a more consistent and homogeneous product.
Typical temperatures for a rotary coke calcining kiln are between 2200°F (1200°C) and 2400°F (1315°C). Alumina-silica refractories in the 40% to 70% Al2O3 range are appropriate for these normal operating temperatures. Petroleum coke calcining operators prefer single-layer brick linings using rotary kiln block (RKB's).
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 ...
At present, the petroleum coke is mainly calcined by vertical shaft furnace or rotary kiln to meet the requirement of prebaked anode used for Aluminum reduction in China.
coke or graphite needle-grade coke depending upon its physical and chemical characteristics with needle-grade coke having a higher purity than anode-grade coke which is used in electric furnaces in aluminum and steel smelting. Petroleum coke calcining may be achieved in a rotary kiln, shaft calciner and rotary hearth. A rotary . kiln
Petroleum coke, at times called "pet coke" for short, is a by-product of the coker process in the oil industry. ... Pet-coke calcining may be carried out in a rotary kiln, rotary hearth kiln, or shaft kiln described in the early chapters. However, the rotary kiln has become the industrial workhorse for this purpose due to its flexibility of ...

Carbonaceous material such as petroleum coke is calcined in the upper part of an air-injected vertical shaft kiln, and steam injected into the lower part of the kiln reacts with hot coke below the combustion zone to produce hydrogen and carbon monoxide.
Petroleum coke (also known as pet coke) is a carbonaceous solid derived from the cracking processes of oil refineries and has been a source of relatively cheap pulverized fuel for the kiln industry. It is called green coke until it is thermally treated into crystalline or calcined pet coke used in the manufacture of electrodes for steel and ...

The calcination process of green petroleum coke in the rotary kiln has been studied in the past years. A schematic of the process is shown in Fig. 1. The process consists of four major equipment, including the drying kiln, the rotary kiln, the incinerator, and the cooler. After removing the moisture
kiln was monitored from four positions along the kiln shaft from the top of the kiln located at 0.17m, 0.47m. 0.77m and 1.07m designated as positions 1,2,3 and 4 respectively. The shaft undergoing the burning cycle( calcining shaft ) is the one usually monitored. The positions are connected with a thermocouple to a
C) are key measures for coke calciners [1]. For rotary kiln calcined coke, calcination levels typically range from an RD of 2.04 to 2.07 g/cm3 and L C of 24 to 29 Å. Due to the different technology of a shaft calciner, the residence times are much longer, and it is not uncommon to see shaft cal-cined product with a higher RD (2.07–2.10 g/cm3 ...
