Hi Johnny Pellin and 25362,
Thanks both for the quick feed back!
I'll check out the literature on the sour water literature thread.
I had already studied the maximize sour water feed inlets thread. It confirmed our conclusion that reboiler vs. direct steam is pretty much a tie. The required energy in form of low pressure steam is the same for both. With direct steam we lose the steam to the waste water, with a reboiler we have the excess capital investment and fouling problems in a second piece of equipment (the reboiler).
The available NPSH is 8.7 m at min liquid level in the tank (pressureless tank, min level at 3 m height, density H2SO4 of 1830 kg/m3, vapor pressure of H2SO4 practically 0).
According to a formula I found in the 27. edition from 1944 of "Die H
