The reaction system is isolated separately using a blind flange, and a temporary nitrogen line is connected from the low point of the cold hydrogen control valve in the hydrorefining reactor and the hydrocracking reactor beds to supply nitrogen into the system in order to maintain a slight positive pressure. (Unless otherwise specified, all questions and answers are based on hydrogenation units.) ) Correct: 3 wealth, Incorrect: 1 wealth ； Mass posting of posts – rated based on the lowest score ； Replies that are unrelated to the answer are considered spam and will be deleted immediately.

Isolate the reaction system using blind flanges, and connect a temporary nitrogen line from the low point of the cold hydrogen control valve in the hydrofining reactor and the hydrocracking reactor beds to introduce nitrogen into the system in order to maintain a slight positive pressure.
