Q & A > Question Details
With Increased pressure, Increased COT, Increased Temperature, & low Residence Time in the Coke Drum, we are facing high gas make with increased Methane in the Gas. High Coking is also seen. The API of the Coker Feed is 3.544. Can anyone explain the reasons why we are achieving high amount of Methane make in the process?

Increase in pressure will lead to increase in cracking and hence increase in gas make because you are allowing higher residence time to the cracked product. Increasing the COT will invariably increase gas make as cracking is an endothermic reaction.
