Hydrogen partial pressure in hydrotreating
Did you know?
WebHydrogen partial pressure (H 2 PP) plays a significant role in hydroprocessing operations. As a rule-of-thumb, catalyst deactivation rate is proportional to the reciprocal of the hydrogen partial pressure factored by an exponential ranging from 2 to 3: Catalyst … WebGROUP II BASE OIL. Hydrogenation is a generic name for treating fuels and lubricants at elevated temperatures, while in the presence of hydrogen and a catalyst. Hydrotreating (often called hydrofinishing) and hydrocracking both are different names for hydrogenation. Hydrotreating is a non-destructive process, whereas hydrocracking is a ...
WebAbsolute pressure in the reactor depends on hydrogen partial pressure in the system, playing the key role in hydrocracking progress, and depends on hydrogen concentration in recycle hydrogen gas. On hydrocracking industrial units, minimum hydrogen content in hydrogen gas is not lower than 80-85 vol. %. WebAs the amount of hydrogen in the feed gas is reduced, the pressure of the feed must be increased to keep a constant partial pressure of hydrogen. Through the use of a hydrogen management program (starting with measurement of hydrogen purity), overall pressure can be reduced taking a load off compressors.
