Division 2 Aromatics benchmark: CWT functions
United Kingdom
Net fresh feed (F), Product feed (P) | |||
| CWT function | Description | Basis (kt/a)f1 | CWT factor |
|---|---|---|---|
| Naphtha/gasoline hydrotreater | Benzene Saturation, Desulfurisation of C4–C6 Feeds, Conventional Naphtha H/T, Diolefin to Olefin Saturation, Diolefin to Olefin Saturation of Alkylation Feed, FCC Gasoline hydrotreating with minimum octane loss, Olefinic Alkylation of Thio S, S-Zorb™ Process, Selective H/T of Pygas/Naphtha, Pygas/Naphtha Desulfurisation, Selective H/T of Pygas/Naphtha. Naphtha hydrotreating factor includes energy and emissions for Reactor for Selective H/T (NHYT/RXST) but capacity is not counted separately. | F | 1,10 |
| Aromatic solvent extraction | ASE: Extraction Distillation, ASE: Liquid/Liquid Extraction, ASE: Liq/Liq w/Extr. Distillation CWT factor cover all feeds including Pygas after hydrotreatment. Pygas hydrotreating should be accounted under naphtha hydrotreatment. | F | 5,25 |
| TDP/TDA | Toluene Disproportionation/Dealkylation | F | 1,85 |
| Hydrodealkylation | Hydrodealkylation | F | 2,45 |
| Xylene isomerisation | Xylene Isomerisation | F | 1,85 |
| Paraxylene production | Paraxylene Adsorption, Paraxylene Crystallisation Factor also includes energy and emissions for Xylene Splitter and Orthoxylene Rerun Column. | P | 6,40 |
| Cyclohexane production | Cyclohexane production | P | 3,00 |
| Cumene production | Cumene production | P | 5,00 |
