Absorption is stable; there is a high amount of hydrogen in the dry gas
Thread Content
The absorption is stable; there is a high amount of hydrogen in the dry gas. It was growing normally before, but now the hydrogen content has reached 65%. What is the reason for this? How should it be dealt with? I need help.
A high hydrogen content in the dry gas indicates a high hydrogen content in the rich gas as well; a high hydrogen content in the rich gas means that the hydrogen content in the reaction oil and gas is also high. In short, any changes in the composition of the products are related to the reaction process. The main reasons for this are either increased catalyst activity or a change in the composition of the feed oil, which leads to an increase in the reaction temperature, or both factors combined. At this time, there is usually an excess of heat, and in addition, it is necessary to prevent the formation of a \"carbon pile\" that might occur.
What does “carbon stack” mean? I’m using 1 million units of diesel for hydrogenation here. Rich gas that comes out.

Not bad; generally, when hydrogenation is involved, it’s not stated that those two towers provide stable absorption: lol
While adjusting the reaction depth, consideration can also be given to the three-phase separation effects of cold heavy fractions, oil, and water. As dissolved hydrogen enters the cold light fractions and the distillation section along with the heavy oil, the hydrogen content in the dry gas will also increase; this is provided for reference only.
Dissolved hydrogen,. Control the pressure and hydrogen purity. How can low scores be controlled?
