【Daily Question 2019】Hydrogen production and hydrogenation section – Questions 5-10: Briefly explain the main reasons why hydrogenation feedstock oil needs to be protected with nitrogen or fuel gas. The main reason for using flare gas to protect hydrogenation feedstock is to isolate it from air, thereby preventing olefins and non-hydrocarbon compounds such as S, N, and O from oxidizing and forming gums. (Unless otherwise specified, all questions and answers are based on hydrogenation units.) ) Setting it to a reply earns 1 wealth point; those who answer correctly receive an additional 2 wealth points, while those who get it wrong receive no points at all. Please have the person in charge update the wealth points consumed by the question setter as soon as possible. Temporarily, the top 60 players will receive +1 to automatic wealth acquisition. 3 correct for wealth, 1 incorrect for 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 from air to prevent oxidation of olefins and non-hydrocarbon compounds, which could lead to the formation of gums
Prevent other gases from entering the mixture, to protect the substance
It prevents aromatic thiol compounds and olefins in the crude oil from being oxidized upon contact with air, thereby avoiding the formation of sediments and gums. Such gums can easily accumulate on the catalyst, increasing the pressure difference in the reactor and reducing the catalyst’s activity.
