| Use advice for data set | When utilizing this Life Cycle Assessment data for p-xylene production, ensure inclusion of emissions from all processing stages, specifically catalytic reforming, separation, extraction, disproportionation, and xylene separation. Consider data from both East China and North China refineries, as referenced in the 2019 Enterprise Production Report, for comprehensive life cycle analysis. The functional unit for analysis is defined as 1 ton of p-xylene product. Users should pay attention to regional variations in technology and emissions, and apply data carefully if generalizing to different geographic locations or production scales. Methodological advice also includes assessing potential for recycling and recovery within the process and accounting for technological applicability across different industry practices. |
| Technical purpose of product or process | The aromatics technology described is utilized for the production of p-xylene in refining and chemical industries. This process relies on naphtha as the primary raw material, and involves catalytic reforming, reformed oil separation, extraction, disproportionation, and p-xylene separation steps. P-xylene produced through this technology is a critical raw material for the manufacture of numerous products, including terephthalic acid (used in polyester production), plastic bottles, and fibers. The aromatics complex, which comprises the reformed oil separation unit, extraction unit, disproportionation unit, and xylene separation unit, is essential in producing high-purity p-xylene suitable for these applications. |
