calcination of raw petroleum coke rotary kiln

Request PDF | Rotary Kiln Petroleum Coke Calcination Process | 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

Jul 16, 2020 Jul 16, 2020 The rotary kiln has a relatively simple production process, focusing on controlling the calcining time and temperature. It can process a variety of petroleum coke, but the rotary kiln cannot

Jan 26, 2021 Jan 26, 2021 Rotary kiln. The green coke is fed from the kiln tail. Due to the tilt of the kiln body, the green coke slowly moves towards the kiln head as the cylinder rotates. Gas or heavy oil is sprayed from the nozzle of the kiln head and mixed with the air controlled by the kiln head to form a high-temperature calcination zone of 5-10 meters long

Calcining petroleum coke of pot furnace and rotary kiln. 2019-7-23 The rotary kiln system has large output, strong adaptability to raw materials, good operating conditions, high degree of automation and easy environmental protection, but the calcined coke has poor quality and low yield and is suitable for centralized production in the coke

Martins et al. (2001) described a steady-state rotary kiln model for the petroleum coke calcination that predicts the temperature profiles for the bed, gas phase and the kiln wall in the axial

Calcination is a high temperature process in rotary kiln for transforming the physical properties of raw petroleum coke. Raw Petroleum Coke (RPC) is fed into a rotary kiln in controlled ratios. During the heat transfer process, the material comes across 3 reactive zones where it drying, removal of residual hydrocarbons and then to densification zones to improve critical physical properties e.g

Calcined Petroleum Coke (CPC) is the product from calcining raw petroleum coke (RPC). The raw coke is the product of the Coker unit in a crude oil refinery. CPC is used to make anodes for aluminium smelting and is also used in dioxide industry, steel and titanium. ... Number of Rotary Kiln: 1: Capacity: 210-220 TPD: Kiln Temperature: 800

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

Calcined Petroleum Coke (CPC) is manufactured from Raw Petroleum Coke (RPC) by the process known as high temperature pyrolysis. The process is carried out in a rotary or vertical kiln at temperatures exceeding 1300 deg C. Calcination of CPC is essentially a high temperature treatment in which the carbon to hydrogen ratio of RPC is increased from 20 to 1000 and above

Rotary kiln calcining petroleum coke is directly heated by flame, while tank calciner receives heat indirectly. When the rotary kiln is calcined, the raw materials enter from the kiln end of the large kiln. Due to the tilt of the kiln body, the raw materials slowly move toward the kiln head as the cylinder rotates

Calcination of Raw Petroleum Coke. Calcined Coke handling and storage. ... The coke is fed then to the rotary kiln. The kiln is preheated before starting the feed to 500 to 550 degree centigrade feed end 800 to 900 degree centigrade at discharge end and approx. During preheating process the kiln is kept rotating at the rate 0

Most of the calcining of petroleum coke is carried out in rotary kilns. In this chapter, we provide some of the characteristics of petroleum coke calcination process in the rotary kiln and use

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

Calcining petroleum coke of pot furnace and rotary kiln. 2019-7-23 The rotary kiln system has large output, strong adaptability to raw materials, good operating conditions, high degree of automation and easy environmental protection, but the calcined coke has poor quality and low yield and is suitable for centralized production in the coke

Calcination is a high temperature process in rotary kiln for transforming the physical properties of raw petroleum coke. Raw Petroleum Coke (RPC) is fed into a rotary kiln in controlled ratios. During the heat transfer process, the material comes across 3 reactive zones where it drying, removal of residual hydrocarbons and then to densification zones to improve critical physical properties e.g. electrical conductivity, real density

by the drying kiln, dried green petroleum coke is then undergone the calcination process in the rotary kiln. Afterwards, it is then cooled to a temperature below 80oC by the cooler. Meanwhile, the flue gas from rotary kiln, consisting of un-burnt particulates and volatile matter
