Some crudes tend to foam more than others. If the foaming is happening after switch, be careful not to inject too much quench steam. If the coke is shot, you may try decreasing heater outlet temperatures. Quench water tends to channel through shot coke. You may also want to track your crude slates to develop a history of how certain crudes react. You can also try adding a little clarified oil to settle things down.
