Reactor V-102
•The catalyst use in this reactor is “cobalt molybdenum”
•The reactions in this reactor:
• H2S
• NH3
Naphtha +H2 = 3- H2O
4- Olefin Removal
5- Halide Removal
6- Metal Removal
•The hydrotreated naphtha sulfur content should be maintained well bellow the 0.5 wt ppm
maximum

Tinput Toutputgas Toutputliquid
133c◦ 83c◦ 197c◦
 This stripper has 25 trays.
 There is used bubble cup in stripper.
 This stripper used to Separates H2Sfrom Naphtha .
 After separate H2Swill go to Amine Unit
 H2Safter separate is 818Nm3/ h.
 Removal of light ends from a liquid by contacting it with an inert medium such as steam or nitrogen.
 Principle : reducing the partial pressure by means of another vapor component and thereby reducing the
boiling point of the liquid mixture.

17. Naphtha splitter V-107
 This splitter has 60 trays.
 The feed is began from tray 25
 There is used bubble cup in splitter.
 This splitter used to Separates light naphtha from heavy Naphtha .
 In product we will have 36% liquid and 64 %gasses.
 The product we have from splitter is 38%light naphtha and 62%heavy naphtha.

 Before any reactor we have heater, so we have 4 reactors and 4 heaters.
 We use heaters to keep Tout constant .
 All heaters is fuel gas heater.
 The catalyst used in reactors is “R232”
