How is the minimum flow rate for the furnace tubes in a delayed coking heater calculated? The specification of our furnace tubes is φ127×12; what is the minimum flow rate for these tubes?

It should be a comprehensive consideration of factors such as the residence time of the oil at temperatures above 426°C (?), the surface heat intensity of the furnace tubes, and the relative coking rate – it can’t be solely related to the tube diameter, right?
