In the given problem, it involves the design of a vertical Thermosyphon reboiler, taken from the bookCoulson and Richardsons Chemical Engineering Series, Chemical Engineering Design, Sixth Edition byRay Sinnott and Gavin Towler. Example $12\mathrm{.}11($page$747)$

In this example, there are several calculation errors, which are not typos or incorrect numbers, but rather errors in calculation principles. Use the knowledge of phase equilibrium calculations on the topic of flash calculation to check and correct the errors. Additionally, there are other errors; find and correct them as well.
