【Q&A Question 096】April 6, 2018: Briefly describe the various methods available to address the issue of unsatisfactory bromine value in refined oil. (1) Increase the temperature at the reactor inlet； (2) Increase the circulating hydrogen flow rate ； (3) Improve the purity of recycled hydrogen ； (4) Reduce the air velocity. (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.

(1) Increase the reactor inlet temperature； (2) Increase the circulating hydrogen flow rate ； (3) Improve the purity of recycled hydrogen ； (4) Reduce the air velocity.
1. Increase the reactor inlet temperature； 2. Improve the purity of recycled hydrogen ； 3. Increase the circulating hydrogen flow rate ； 4. Reduce the air velocity.
Increase the reaction temperature, enhance the degree of hydrogenation, and raise the olefin saturation rate； Increase hydrogen partial pressure ； Increase the amount of new hydrogen injected.
Increase the reactor inlet temperature； Increase the circulating hydrogen flow rate ； Increase the purity of recycled hydrogen ； Reduce the air velocity.
1. Reduce olefins in non-aromatic oils; 2. Use the 481-3 hydrogenation refining catalyst to remove olefins.
