Selection and design of the condenser
Thread Content
This post was last edited by Black Cat and Milk on 2020-4-18 at 22:20. A beginner seeking design guidance! The components of the exhaust gas undergoing desorption are 1.94% chloroform by volume, with the remainder being nitrogen; the temperature is 100°C, the pressure is at atmospheric level, and the mass flow rate of the gas entering the system is 0.413 kg/s ； A 40% ethylene glycol solution is used as the cooling medium to condense the desorbed gas to 10°C; the inlet temperature of the coolant is -15°C and the outlet temperature is 0°C. A horizontal shell-and-tube condenser is planned to be used for this purpose. Can a horizontal shell-and-tube condenser meet my condensation requirements? Is it necessary to install an additional cooler? (I had no prior knowledge of heat transfer and condensation, so it was difficult for me to fully understand the design of condensers at first.) I welcome any advice; thank you
If the heat load is calculated using the method shown in the diagram, then in the case where chloroform condenses only once, is the temperature difference in the condensation section the difference between the temperature on the inner wall of the heat transfer tube and the dew point of chloroform?
Is this design meant for purchasing equipment?
