Thermal cracking process for upgradation of heavy residue has been used since long and still it is playing an important role in the modern refinery through upgradation of heavy residue and improving the economics of the refinery through the production of lighter distillate and other valuable product like low value fuel gas and petroleum coke. Although petroleum coke was first made by North Western Pennsylvanian the 1860’s using cracking, however, a real breakthrough in the thermal cracking process was with development of the first cracker by William Burton and first used in 1913.Heavy residues are a mixture molecules consisting of an oil phase and an asphaltene phase in physical equilibrium with each other in colloidal form. Asphaltenes are high molecular weight, relatively high atomicity molecules containing high levels of metals. During thermal cracking, the long molecules thus depleting the oil phase in the residue. Asphaltene cracking is the most difficult component to process and asphaltenes in the feed remain unaffected, additional asphaltenes may be formed by secondary polymerisation reactions. At a certain condition asphaltenes is disturbed and asphaltenes precipitate. At this stage of conversion the product residue becomes unstable. Under condition of thermal cracking, hydrocarbons, when heated, decompose into smaller hydrocarbon molecules. The UOP thermal cracking process is based on two coil design for selective cracking of topped or reduced crudes into valuable products >3500 C. Table M-VI 4.2 shows the various thermal cracking process and process conditions.
