Rotary KilnThe petroleumgreen cokeis fed into arefractorylinedrotary kilnwhere the volatiles are driven off during the calcining process in an oxygen deficient atmosphere. Air can be injected through thekilnshell to burn a portion of the volatile matter in thekilnproviding usable heat to thekiln.Cooling: Once thecalcined cokeis discharged from thekiln, thecokeis cooled in arotarycooler.Get Price
Calcined petroleum coke(CPC) is created fromgreen petroleum coke(GPC), a by-product of refining crude oil. While CPC can be created using a number of processes -- includingrotary kiln, hearth and vertical shaft technologies -- the high-temperature conversion fromgreen coketocalcined cokealters the material in key three ways: Drying.

The results were compared with actual industrialrotary kilndata in order to validate the simulation and there was a reasonable agreement for the two different GPCs considered. The methodology of kinetics-based simulation described in this study may be used to predictcokecalciningkilnsperformance regardless of thegreen cokecomposition.

Rotary kilnsare available in either a direct- or indirect-fired configuration and are often referred to as a calciner. The production of expanded clay aggregates is typically carried out in a direct-firedkiln, in which the clay and products of combustion are in direct contact with each other.
Coke-calcining plants receivegreenpetroleumcokefrom oil refineries. Thegreen cokeis blended and fed intorotary kilnsoperating up to 2800°F under a reducing condition. The material exits therotary kilnas calcinedcokewith a correct crystalline structure and electrical conductivity properties.
Calcined PetroleumCokeis a critical ingredient in the production of aluminum. It is created by placing high quality raw "green" petroleumcokeintorotary kilns, where it is heated to temperatures between 1200 to 1350 degrees C (2192 to 2460 F).
During thecalcinationprocess, the GPC is heated to remove the volatiles and sulfur to produce purified calcinedcoke, which is used in the production of graphite, electrodes, metal carburizers, and other carbon products. Currently, more than 80% of calcinedcokeis producedin rotary kilnsorrotaryhearth furnaces.
