How much of the steam generated in the flash tank of the steam generation system condenses through the pipes?
Thread Content
The steam generated by hot water in the flash tank condenses partially in the pipes, and then it is separated in a steam-water separator. I would like to know approximately how much water vapor condenses in the pipes
What you’re saying is too general; it’s related to many factors – things like your steam pressure, the length of the pipes, whether they are insulated, and the ambient temperature all have an impact
First, thank you, and then I’d like to express my confusion. The issue lies in the design aspect of this evaporation process. The available conditions are the feed state and the state of the steam product. The proposed process involves high-temperature water first passing through a flash tank for flashing; the resulting steam then enters a steam-water separator for separation. My concern is that in Aspen’s simulation, the vapor fraction of the steam after flashing is 1, meaning it’s entirely steam. In that case, there’s no point in using a steam-water separator, as some of the steam will definitely condense in actual production, which is when the steam-water separator becomes useful. So I don’t know how to design such a process using Aspen!
In the flash tank, it’s sufficient not to specify the temperature and pressure; specifying adiabatic conditions and pressure is sufficient, and this also corresponds to reality.
It refers to the specified adiabatic conditions and pressure; now that the pressure in the flash tank has been determined, everything that flashes out will be steam. By the way, is the vapor-liquid separator also simulated using the Flash2 module?
It’s flash2, but after flashing everything turns into steam – is it really that effective? Or is the water pressure very high? Under normal circumstances, it should be a vapor-liquid mixture
The amount of condensation depends on the temperature and pressure in the pipeline after flashing; using Pipe to simulate the pipeline will suffice.
Okay, three grams of oil! ! ! ! ! ! ! !
