Who can use HTRI to help me calculate a reboiler?
Thread Content
For a vertical reboiler, the heating steam at 0.4 MPag flows through the shell side, while the process fluid, which is water at 102 degrees Celsius, flows through the tube side at a flow rate of 1154 kg/h; the water is vaporized 100%. I used the HTRI method to calculate a heat exchange area of 40 square meters. However, according to the heat transfer coefficients for evaporators listed in chemical process manuals, the coefficients for water vapor and water are quite high, around 2260; based on these values, the calculated heat exchange area is only a few square meters. Could someone help me figure out what’s going on here?
What are the inlet and outlet temperatures of the heating steam? What is the pressure of the water being heated? ,,, At a glance, you seem to be a female college graduate who has just finished school. . .
