Depth of residue hydrogenation reaction
Thread Content
When the degree of reaction in residue hydrogenation is too high, the hydrogen consumption increases, the temperature rise in the catalyst bed rises as well, the inlet temperature of the hot fractionator increases, and there is more liquid phase in the cold fractionator. What is another obvious manifestation of this? In other words, under unchanged reaction conditions, which parameter best reflects the degree of reaction intuitively?
Residue hydrogenation? Liquid-phase hydrogenation or gas-phase hydrogenation
Or check the valve opening degree as it moves from high cold temperature to low cold temperature
After hydrotreating of residue, the light components at the top of the separation column increase; the fractions in various measurement lines also increase, as does the amount of acidic gases
The reaction pressure will decrease, and the amount of recycled hydrogen will also decrease
