What is the typical inlet pressure of steam when calculating a reboiler?
Thread Content
As the title suggests, what is the typical inlet pressure of steam used when designing reboilers in engineering? Should steam generally be routed through the tube side or the shell side? Thank you :)
Generally, steam flows through the shell side; stainless steel is used mainly because the medium to be heated may be corrosive, while carbon steel is sufficient for the steam side. As for the use of pressure, it mainly depends on the temperature of the medium being heated; generally, the saturation steam temperature at that pressure is higher than the temperature of the medium being heated, and a certain temperature difference is sufficient.
For example, the saturated vapor pressure of water at 140°C is 350 kPa; so if I use steam at 140°C for heating, will my inlet pressure be 350 kPa? Thank you
