C. Thermal siphon reboilers are smaller than tank reboilers
C、-----------------------------------------
Compared to the vaporization rate of tank-type reboilers, that of thermal siphon reboilers is ( ) A. Higher than that of tank-type reboilers
Answer: C. The thermal siphon reboiler is smaller than the kettle reboiler. Explanation: The vaporization rate of a thermal siphon reboiler is generally set at less than 15%, whereas that of a kettle reboiler can reach 80%
Compared to the vaporization rate of tank-type reboilers, that of thermal siphon reboilers is (C): A. Higher than that of tank-type reboilers; B. Equal to that of tank-type reboilers; C. Lower than that of tank-type reboilers. (1) Horizontal thermal siphon reboilers are much smaller in size; (2) In thermal siphon reboilers, the oil is heated and its temperature rises, causing some of it to undergo vaporization, but there is no space for vaporization within the device, so no separation between gas and liquid occurs; tank-type reboilers, on the other hand, have a space dedicated to evaporation; (3) Due to boiling-based heat transfer, thermal siphon reboilers have a high heat transfer coefficient, and thus despite having a smaller heat transfer area, they can handle a large heating load; (4) Tank-type reboilers function like a theoretical tray in a distillation column.
C. Thermal siphon reboilers are smaller than tank reboilers
C. Thermal siphon reboilers are smaller than tank reboilers
A. The thermal siphon reboiler is superior to the tank reboiler
