Which parameter conditions in a delayed coking unit cause an increase in dry gas yield?
Thread Content
Generally, the dry gas yield in delayed coking units is less than 5%, but it is unclear which parameter was not controlled properly, resulting in the dry gas yield rising to over 5.5% How to adjust it?

There are many factors that can cause an increase in the amount of dry gas: a high outlet temperature of the heating furnace, high reaction pressure in the coke tower, the inclusion of some light-component oils, the reprocessing of catalytic slurry, changes in the properties of raw materials such as ethylene oil, and so on
