What percent vaporization should a fired heater in naphtha reboiler service be designed for?

RE: fired reboiler

New = 50 wt% max.
Revamp = 75 wt% max.


RE: fired reboiler

You make specification (% vaporization) according to process requirement. Reboilers are design to generate specific amount of vapor to assure L-V Traffic in distillation column.

Maximum vaporization in the coil should be limited to about 80 wt%. this is to avoid coking or fouling problem by dry point in the coil.
