Coker naphtha hydrotreating - DigitalRefining

For new grassroots units, a three-reactor layout is typical. In the first reactor, diolefins are mainly saturated at low temperature. In the second, silica is adsorbed on high-surface area catalysts known as silica guard. Simultaneously, most of the olefins are saturated, while a relatively large degree of HDS and a small degree of HDN take place.

Refinery Operations | » Identify Hydrotreating Process .

General Rules of Thumb Concerning Hydrotreater Reactors. Hydrogen Consumption: – Each °API increase results in approximately 100 scfb H 2 consumption – Each increase in Cetane number (1.0) leads to approximately 100 scfb H 2 consumption in diesel. Unless the feed is very high in sulfur, most H2 consumption comes from either PNA saturation .

The reactor temperature is a function of the density of the feed, the degree of sulfur removal desired, and the activity of the catalyst. As the oil–hydrogen stream passes down-flow through the reactor, it contacts the catalyst and the hydrogenation reactions take place. These reactions are highly exothermic, and it is necessary to inject .
