Recently, the second public announcement regarding the environmental impact assessment for “Zhuhai Hongcai Fine Chemicals Co., Ltd.’s 1.5 million tons per year continuous reforming aromatics production facility” was posted online. According to the public information, Zhuhai Hongcai Fine Chemicals Co., Ltd. plans to invest 2,177.94 million yuan to carry out this project in the petrochemical zone of the Gaolan Port Economic Zone in Zhuhai. The main construction items include the installation of 1 set of naphtha pretreatment unit with a capacity of 1.2 million tons per year, 1 set of continuous reforming unit with a capacity of 1.5 million tons per year, 1 set of PSA unit with a capacity of 90,000 Nm3/h, and 1 set of isomerization unit with a capacity of 200,000 tons per year. Additionally, 1 LNG vaporization station (for internal use) will be built, along with 1 heat recovery unit for process water. There will also be 1 benzene storage tank cluster consisting of 6 internal floating roof tanks with a total capacity of 12,000 m3, 1 C5 storage tank cluster comprising 4 spherical tanks with a total capacity of 8,000 m3, 1 power station equipped with 1 steam boiler capable of producing 130 t/h of steam, 2 desalination units each with a capacity of 140 t/h, 2 condensate treatment units each with a capacity of 100 t/h, 4 sewage lifting stations, 1 foam treatment station, 1 substation, and 1 on-site cabinet room. Some of the auxiliary facilities will be provided by Huafeng Petrochemical. The product plan for this project is to use naphtha produced by Huafeng Petrochemicals as well as purchased naphtha as raw materials, and through processes such as pretreatment, continuous reforming, extractive distillation, and isomerization, to produce 75,300 tons per year of benzene, 312,100 tons per year of toluene, 397,800 tons per year of mixed xylene, 393,600 tons per year of heavy aromatics, 102,200 tons per year of solvent oil, 193,600 tons per year of isomerized oil, 62,200 tons per year of hydrogen, and 47,800 tons per year of liquefied gas. ? The project consists of the main engineering, storage and transportation engineering, auxiliary engineering, and environmental protection engineering. The 1.2 million tons/year naphtha pretreatment unit adopts a full-range hydrogenation process flow ； ? The 1.5 million tons/year continuous reforming unit utilizes UOP’s Cyclemax technology (including the Chlorsorb chlorine adsorption process), while aromatic extraction is carried out using the SED process developed by the China Petroleum and Chemical Research Institute (sulfolane extraction distillation process) ； ? The 200,000 tons/year isomerization process utilizes the Par-Isom isomerization technology developed by UOP ； The 90,000 Nm3/h PSA unit uses reformed hydrogen and light gas from Huafeng Petrochemical as raw materials; after purification via PSA, the hydrogen is sent to the hydrogen pipeline network. The PSA unit employs pressure swing adsorption technology for hydrogen concentration. ? The raw materials for this project are either domestically produced naphtha or purchased naphtha, while the auxiliary materials include various catalysts and chemical agents.
