Aromatics Complex.The complete set of aromatics technology is currently the main process for the production of p-xylene in refining and chemical enterprises. Using naphtha as raw material, after catalytic reforming, reformingThe complete set of technology for the preparation of aromatics through the steps of whole oil separation, extraction, disproportionation, and xylene separation is currently the most important technology for refining and chemical enterprises to produce p-xylenemain process. Using naphtha as raw material, the p-xylene product is prepared through catalytic reforming, reformed oil separation, extraction, disproportionation, xylene separation and other steps, including reformed oil separation unit, extraction unit, disproportionation unit and xylene Separation units are collectively referred to as aromatics complexes. 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.
