Coking | FSC 432: Petroleum Refining

Three different coking processes are used in the refineries: delayed coking, fluid coking, and flexi-coking (a variation of fluid coking). The common objective of the three coking processes is to maximize the yield of distillate products in a refinery by rejecting large quantities of carbon in the residue as solid coke, known as petroleum coke.

Petroleum coke - Wikipedia

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 aluminum extraction.

PETROLEUM COKE: ESSENTIAL TO MANUFACTURING

Petroleum coke, or petcoke, is a product produced from all types of oil (light/heavy crudes) during the oil refining process. Many different products are extracted from a barrel of crude oil in addition to gasoline, diesel and jet fuels. Petroleum coke just one of the many. Petroleum coke is not a new product and has been produced since the 1930s.

Petroleum Coke Calcining Systems - Outotec

Basic calcining process. Petroleum coke calcining is a three step process, including drying, devolatization and densifiion. The coke calcining process is a time-temperature function, conducted in an oxygen deficient atmosphere. Important control variables are heating rate, air addition rate and final calcination temperature.
