I am curious to see the response to this question. I would think that direct injection of steam versus the reboiling of stripped sour water from within the tower would add water to the system, which is trying to process a waste stream, sour water. We are usually maxed out on sour water stripping capacity, so increasing the volume of water to be processed is a step in the wrong direction. We did consider going to live steam addition when we fouled a reboiler, but I don’t think we ever installed it.
