Modeling and simulation of petroleum coke

2001-9-1  The calcination of green petroleum coke in rotary kilns presents low operational costs due to the fact that the process is energy self-sufficient (i.e. does not require fuel), and that it presents higher processing capacity compared to the conventional processes.

When green coke quality changes significantly, it is easier and quicker to adjust a rotary kiln due to the high level of automation and multiple control variables available. There are also no fundamental differences in coke CO2 and air reactivity between the technologies.
