【Daily Question No. 269】September 27, 2017. Which of the following equations for calculating the hydrogen partial pressure in a hydrogenation unit is correct? ( ) A. Hydrogen partial pressure = Total pressure * Volume fraction of hydrogen in (circular hydrogen – fresh hydrogen)
B. Hydrogen partial pressure = Total pressure * Volume fraction of hydrogen in fresh hydrogen
C. Hydrogen partial pressure = Total pressure * Volume fraction of hydrogen among all gas molecules
D. Hydrogen partial pressure = Total pressure * Average volume fraction of hydrogen in circular hydrogen and fresh hydrogen
The reference answer can be seen after repeating; scoring is possible by identifying the key points. (Unless otherwise specified, all questions and answers are based on hydrogenation units.) ) The answer to the daily activity question has changed; today’s answer will be shown in subsequent questions.
