Pressure in gasoline hydroprocessing
Thread Content
I saw a presentation stating that the reaction pressure for gasoline hydrogenation is less than 2.0 MPa. As far as I know, the hydrogenation refining of diesel and gasoline generally takes place at pressures above 5.0 MPa. I’m not sure what the reaction pressure is for pure gasoline hydrogenation units according to what others know
1.2-1.6 MPa is sufficient; this is selective gasoline hydrogenation.
What was said upstairs is completely correct! Top! ! ! ! ! ! ! ! !
Generally, it is 2.0 MPa
For pure coker gasoline hydrogenation units, the pressure at high temperatures is controlled at 3.0 MPa
5.0 MPa is the nominal pressure of the design unit. Because a working pressure of 2.0 MPa requires a hydrostatic test during the construction acceptance phase, and this test involves pressures higher than 2.0 MPa; moreover, the American standard does not offer nominal pressure ranges of 3.0 or 4.0 MPa
The pressure selected for the hydrogenation refining unit varies depending on the specific gravity of the feedstock; generally, the higher the specific gravity, the higher the pressure level! For gasoline hydrogenation, the pressure is around 2.0 MPa; for diesel hydrogenation, it is around 6.0 MPa. Wax oil hydrogenation takes place at around 9.0 MPa, while the pressure for residue oil hydrogenation ranges from 10.0 to 20.0 MPa
