A beginner in the chemical industry seeking advice on heat exchanger design
Thread Content
Process thermal fluid hydrogen at 80°C, containing saturated water, cooled to 40°C, 1000 NM3/h. Cooling water 32→37℃. Does this involve a phase change (condensation of water vapor)? What is the heat exchange area approximately? The coefficient is 100 KCAL/M2*℃. Hydrogen 0.305 Kcal/NM3*℃
The amount of saturated water is calculated based on the saturated vapor pressure; by determining the amount on a wet basis, that is, the actual amount, it is possible to calculate the heat load. The amount of water vapor that condenses depends on the partial pressure – this isn’t something that can be determined arbitrarily; it needs to be calculated. The amount of condensation varies greatly depending on the heat transfer coefficient
I’ve calculated that I need to figure out the water volume first
This isn’t a design for a heat exchanger; it’s actually a thermal balance calculation
Just simulate it with Aspen+EDR, that’s fine

I have some learning materials; +V13701289271 to forward some to you
In other words, 291 – 51 = 240 g/m3 of water has condensed; how is the heat absorbed calculated?
Will HTRI be used for calculation? It’s relatively simple
Bro, what kind of software is this?
