| Description |
Effective utilization of residues has become a necessity for refiners in the present time. Refiners have
developed innovative business strategies but the key long term driving force for processing heavy
residues, strategies are; the need for flexibility to handle heavy/high metals crude residues and the
economic benefits of being able to convert low value residue to high value light transportation fuels,
hydrogen and electric power. Delayed coking process has the capability to achieve the desired value
addition. In India the delayed cokers in the eastern sector are processing Assam mix crude and are
producing metallurgical grade coke due to available feed stock quality. The other refineries, processing
imported crude residues, are producing inferior (fuel grade) quality coke due to high sulphur, high
asphaltenes contents in the feed. In near future in India almost all existing and new refineries are planning
to put delayed coker units to process the vacuum residue (imported crude origin) for residue up gradation.
Variation in certain operating parameters makes more distillate per barrel of a given feed. So in the
present case increase in fGrnace outlet/coke drum temperature has been studied using vacuum residue
as feed stock obtained from imported crude origin. In this paper an attempt has been made to see the
effect of variation in the range of 400 to 500°C coking temperature on quality and quantity of the produced
coker products. During the study it has been observed that with the increase in coking temperature the
yield of gas and liquid products increases while coke quantity decreases. Quality wise in gasoline fraction
olefins and aromatics content increases. With the increase in temperature of operation, crystallinity and
calorific value of raw petroleum coke produced at different coke drum temperatures has been measured.
