The Compression 1 and 5PV-1613 CWS 13PV-2311 2 System compresses make-up Fuel Gas KO Drum hydrogen from the Reformer Hydrogen Header in two stages PV-217 13J-106/107 and supplies it to the Reaction and #3 HDS Compressor Separation System to make up for Oil Filtration Pump Recycle Hydrogen to 13EX-2331 hydrogen losses. Compression 1 and 2 System 2  Overview: Sweetened recycle hydrogen from the #3 The Recycle Hydrogen Compression Subsystem receives, compresses, and supplies recycle hydrogen to the #3 HDS Reaction and Any remaining liquid present in the steam HDS Absorber (13PV-2306), located in the and nitrogen stream is removed from the #3 HDS Absorption System, is sent to the Separation System. In the HDS reaction, increased hydrogen partial pressure results in a decrease of coke deposits on the catalyst, thereby silencer and sent to a drain. Recycle Hydrogen Knock Out (KO) Drum enhancing the reaction. Therefore, the #1/#2 Distillate Hydrogen Compressor West/East compresses the recycle hydrogen to main tain the 5 (13PV-2314). adequate hydrogen partial pressure in the reactor. The compressors each consist of one dedicated recycle hydrogen cylinder.
