steam recovery suggestions?
(OP)
hey guys i've a sizable amount of steam coming out of the atmospheric flash drums and its thought that recovering the steam might be profitable. Aside from passing the steam through a heat exchanger... any other options? The heat exchanger isn't an attractive option is because of its impact on the other heat exchangers down the line. there's quite a bit of steam to condensate -- 20,000lbs/hr!

Here in NYC we do grab some BTU's out of an atmospheric flash tank by running coils through them to preheat cold water. Here it is not really a heat exchanger but rather a designed flash tank with coils, so it does not effect the backpressure on the condensate.
Hope this helps.

Even better is to insure that heat utilization at higher temperatures is close to the minimum energy requirements (i.e. pinch analysis), and that useful waste heat is recovered before letdown to atmospheric pressure. This will insure minimum flash steam generation.
