Effect of hydrocracking reaction pressure on the efficiency of hydrorefining
Thread Content
“The effect of reaction pressure is manifested through the hydrogen partial pressure, which determines the operating pressure in the system, the hydrogen-to-oil ratio, the purity of the recycled hydrogen, and the gasification rate of the feedstock. ”How should this sentence be understood? Please give me your advice
It can be understood in this way: once the reaction hydrogen partial pressure is determined, it becomes possible to determine the operating pressure of the system, the hydrogen-to-oil ratio, the purity of the recycled hydrogen, as well as the gasification rate of the feedstock. In other words, the hydrogen partial pressure is an input condition for hydrogenation design.
What components are included in the reaction pressure? What else is there with hydrogen pressure?
The main components are circulating H2S, the actual H2 partial pressure, and some light hydrocarbons; operation remains stable with generally little change in their respective proportions
Cyclic hydrogen contains carbon monoxide, carbon dioxide, hydrogen sulfide, methane, and hydrogen; the combined concentration of carbon monoxide and carbon dioxide is less than 30 ppm
