Hi everyone,

I'm working on design of a catalytic reforming unit project.

There is a heat recovery steam generation from fired heaters of reforming reactors.

In preliminary design, two water circulation has been considered for circulation water from disengaging drum through stack of  fired heater then back to drum. 

Owner requested to reconsider the design so that it is possible to remove circulation pumps.

currently elevation of drum is 12m and elevation of steam generation section of fired heater is from 15m to 20 m.

I'm seeking related guideline or design practice for this system , for example as I know there are some considerations for example rate of circulation should be  15 times more than steam generation rate. I'm seeking some guidelines for these considerations to do hydraulic calculations for a natural circulation. 

 

Please guide me if anyone has related experience.

It seems very unusual to have a steam drum below the heat input section. I don't think this would work well with a natural circulation if you are not going to increase the steam drum height. Steam generation has been practiced for many years. I suspect you need to give yourself a crash course or find someone with expertise. A few references to consider finding:
