【Q&A Question 063】Why is it necessary to use hot hydrogen at a constant temperature to carry the oil after the hydrogenation process was stopped on 2018.03.04? Answer: After the hydrogenation process is stopped, a large amount of oil remains in the catalyst bed. If this oil is not removed, it will hinder the subsequent regeneration of the catalyst and cause coking. Therefore, it is necessary to remove all the remaining oil after the process stops; this is also essential for ensuring safety during that period. (Unless otherwise specified, all questions and answers are based on hydrogenation units.) ) Due to the limitations on the number of posts in the “One Question per Day” section, “One Image per Day” has been moved to the registered devices section; you can access it through the directory I posted.
