Conditions for high-temperature hydroprocessing of diesel
Thread Content
Up to what level of diesel hydrotreatment volume is it necessary to use a high-temperature process, and what is the reason for heating to high temperatures? . . Seeking advice from the great HaiChuan
You can refer to this post: https://bbs.hcbbs.com/forum.php?mod=viewthread&tid=1082893. There is also an article titled \"Comparison between the Hot High-Pressure Process and the Cold High-Pressure Process in Jet Fuel Hydrogenation Units\", written by Li Zhengrong from Sinopec Engineering Construction Co., Ltd.; it provides a detailed discussion, and I believe it is also applicable to diesel hydrogenation.
The main advantage of heating high scores is energy savings, but it increases the cost of the installation; the specifics need to be determined based on the amount of energy saved and the payback period for the investment
There isn’t much processing capacity for heating high-temperature fractions; high-temperature fractions can have their heat recovered, thereby reducing the energy consumption required for distillation, but hydrogen consumption remains high
