Method for producing high VCM coke

摘要

A process and apparatus for improving the production of coke having a high volatile combustible material content are disclosed. The process may include, for example: heating a coker feedstock to a coking temperature to produce a heated coker feedstock; contacting the heated coker feedstock with a quench medium to reduce a temperature of the heated coker feedstock and produce a quenched feedstock; feeding the quenched feedstock to a coking drum; subjecting the quenched feedstock to thermal cracking in the coking drum to (a) crack a portion of the quenched feedstock to produce a cracked vapor product, and (b) produce a coke product having a volatile combustible material (VCM) concentration in the range from about 13% to about 50% by weight, as measured by ASTM D3175.

1. A process for producing a coke fuel, the process comprising:
heating a coker feedstock to a coking temperature to produce a heated coker feedstock; transferring the heated coker feedstock to a coking drum, wherein during transfer the heated coker feedstock undergoes thermal cracking; contacting the heated coker feedstock with a quench medium proximate an inlet of the coking drum to reduce a temperature of the heated coker feedstock and produce a quenched feedstock; feeding the quenched feedstock to the coking drum; subjecting the quenched feedstock to thermal cracking in the coking drum to (a) crack a portion of the quenched feedstock to produce a cracked vapor product, and (b) produce a coke product having a volatile combustible material (VCM) concentration in the range from about 13% to about 50% by weight, as measured by ASTM D3175.
