Resid hydrotreating unit
WebTreating units - A number of process unites improve a hydrocarbon stream by removing impurities and changing some chemical properties, but without changing the refinery's product yield. Good examples of this are the hydrotreaters. Supporting process units - This includes utilities and and other non-hydrocarbon processing units.

WebThe block flow diagram of a typical hydrotreater is shown in Figure 2 below. The feedstock from the upstream processing unit of a refinery is first heated in the furnace and then sent to the reactor for hydrotreating. The effluents from the reactor are separated in a high and/or low-pressure separator into hydrogen gas and liquid product.
WebThe reactors in the hydrotreating unit may be fixed bed, moving bed, ebullated bed or a combination. A guard bed protects downstream catalyst from metals and contributes to sulfur removal.
