Heat exchanger load
Thread Content
Could the experts please help calculate what the required steam load is? Reboiler at the bottom of Tower 1 ； The medium being heated is C3 and C4; the flow rate is 148,001 Kg/h, the inlet temperature is 98 degrees, and the desired outlet temperature is 103 degrees. What is the amount of steam at 1.0 MPa required? Reboiler at the bottom of Tower 2 ； The medium to be heated is butane and gasoline, with a flow rate of 450,002 Kg/h. The inlet temperature is 92 degrees, and the desired outlet temperature is 105 degrees. What is the required amount of steam at 1.0 MPa? Reboiler at the bottom of Tower 3 ； The medium to be heated is carbon tetrafluoride and gasoline; the flow rate is 162,001 Kg/h, the inlet temperature is 152 degrees, and the desired outlet temperature is 172 degrees. What is the required amount of steam at 1.0 MPa?
I guess this person isn’t in design. Without providing the heat load of the reboiler, the composition of the heating medium, or the specific heat, not even a genius could figure it out.
Many more data are needed, such as the condensation temperature of water vapor, the specific heat capacities and composition of mixed C3 and C4 hydrocarbons, as well as the physical and chemical properties of water vapor in its inlet and outlet states; calculations can then be performed based on energy balance
