In cokers always pay giving up something to increase throughput; it has been my way of running cokers. If heaters safety limits are not exceeded, then go for it. Typically Coke drums are the limitations, especially in latest designs where overdesign hardly gets to 110%. Also feedstock is getting worse and most likely will eat that extra 10%.
In summary, make sure maximizing your heaters and everything else, but watch closely your drums; you will recover faster from heater tubes fouling and even plugging, but coke drum foamover would be a killer.
Just my thoughts..
