SAGD Steam Reboiler?

SAGD Steam Reboiler?

SAGD Steam Reboiler?

(OP)
Well I think thats what it is called.

I need some direction on finding budgetary quotes for a heat exchanger (a reboiler?) that will generate the downhole 900# saturated steam from the steam/fluid from another solid fuel fired boiler.

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.

RE: SAGD Steam Reboiler?

Most SAGD operations use an OSTG (once through steam generator), a fired water tube boiler that produces saturated steam of about 80% quality (or, typically, as required to avoid concentrating the boiler water too much so that silica scales, etc, form).
The only use for a reboiler that I could think of is to extract heat from the salty blowdown (the liquid phase from the steam separator .. the steam is sent downhole).
