Reboiler for Steam Production?

Well I think that's what it is called.

I need some direction on finding budgetary quotes for a heat exchanger (a reboiler?) that will generate the 900# saturated steam for a SAGD oil recovery process. The primary boiler will burn solid fuel.

The thinking is this. The return water from the SAGD process is NASTY and we don't want that in our solid fuel fired boiler. Wouldn't it be easier to clean the tubes of a shell & tube HX than the fossil boiler.

So for generating 1000 klb/hr of 900# sat. steam. What would that HX look like and who sells them?

Thanks,

Todd K.
 
FYI, a "reboiler" is what is used to heat the bottom liquids of a distillation column, not generate steam. What you're interested in is a waste heat boiler.

Off the top of my head, I doubt the return water temperature from this SAGD process is going to be hot enough to generate 900# steam without supplemental firing. You need to do a thermodynamic balance first to determine if it's even feasible.
 
Reboilers are used to generate steam in a heavy oil fired power plants, and most especially in a supercritical power plants, where any leakage of the nasty fuel oil into the steam/condensate side of the heater would result in contamination of the boiler feed water.

Main steam is used to drive the reboiler to produce a lower pressure steam for the fuel oil heat exchangers, and storage tank heating. Since the main steam is always at a higher pressure than the steam generated by the reboiler, any leakage would be into the low grade steam.

You may get a better response by posting this question over on the Boiler and Pressure Vessel forum.

If you're looking for experts in the field of steam generation with indirect fluids at 900 psig, go to Vogt in Louisiville, Ky. They have the expertise, experience, and are backed up by years of successful engineering design in this type of application. They are quality machinery producers in this field and have led the industry with their valve and fittings products as well.
