Abstract:
The present invention relates to delayed coking of heavy petroleum residue producing petroleum coke and lighter hydrocarbon products. The invented process utilize a pre-cracking reactor and a reactor furnace for mild thermal cracking of the feedstock and an intermediate separator, before being subjected to higher severity thermal cracking treatment in a coker furnace and a coking drums, resulting in reduction in overall coke yield.

Claim (Index 2):
A method of reducing overall coke yield said method comprising the steps of:\n (a) heating a hydrocarbon feedstock ( 59 ) in a reactor furnace ( 60 ) to obtain hot feed ( 61 ); (b) introducing the hot feed ( 61 ) of step (a) to a pre-cracking reactor ( 62 ), where it undergoes mild thermal cracking reactions to obtain an outlet product material stream ( 63 ); (c) passing the outlet product material stream ( 63 ) of step (b) to a main fractionator ( 69 ), where it fractionated to a heavy bottom fraction ( 64 ); (d) passing the heavy bottom fraction ( 64 ) of step (c) to a coker furnace ( 65 ) to obtain hot hydrocarbon stream ( 66 ); (e) passing the hot hydrocarbon stream ( 66 ) of step (d) to preheated coke drums ( 67 ), where it undergoes thermal cracking reactions to obtain product vapors ( 68 ); and (f) passing the product vapors ( 68 ) of step (e) to the main fractionator ( 69 ) column to obtain desired product fractions.
