A heat exchanger should be selected
Thread Content
Operating conditions of the kerosene cooler capable of processing 400,000 tons of kerosene per year: (1) Kerosene: inlet temperature 140°C, outlet temperature 40°C. (2) Cooling medium: tap water, inlet temperature 30°C. The exit temperature is optimized through economic considerations. (3) Allowable pressure drop: not more than 1000 KPa. (4) Operation is continuous for 24 hours a day, 330 days per year. (5) Maximum pressure that the equipment can withstand: P = 2.5 MPa. (6) Physical property data of kerosene at its characteristic temperature: density of 825 kilograms per cubic meter, viscosity of 7.15×10-4 Pa·s, specific heat capacity of 2.22 kJ/(kg·°C), and thermal conductivity of 0.14 W/(m·°C). Should a fixed-tube-sheet heat exchanger or a floating-head heat exchanger be chosen? . . . . Students are asking experts to provide answers
However, in terms of temperature, there is a significant difference; the outlet temperature of the circulating cooling water must be below 40°, as this facilitates effective counterflow heat exchange. It is recommended to use a floating-head type design first, but such designs are prone to internal leakage. If that option isn’t feasible, then a U-tube type design should be chosen.
Fully welded plate heat exchangers should also be feasible
Plate heat exchangers are the most suitable option; kerosene and tap water are both relatively clean. Tap water requires less usage, which helps save water and space. For a detailed plan, feel free to contact me
Floating-head heat exchangers are quite common and suitable for various applications
Wide-channel plate heat exchangers can be selected
