The construction progress of the “100-billion-level” refining and chemical aircraft carrier-Zhejiang Petrochemical’s 40 million tons/year refining and chemical integration project has attracted much attention in the industry.
Since late May 2019 , Zhejiang Petrochemical’s first-phase units are starting up one after another. The main units that have been put into operation are atmospheric and vacuum units, light hydrocarbon recovery units, sulfur recovery units, delayed coking units, product refining units, naphtha hydrogenation units, and aviation fuel hydrogenation units. , wax oil hydrogenation unit, aromatics reforming unit and refining intermediate tank area, etc.
In addition, it also includes power center, desalination center, sewage treatment, tank terminal, Public works such as the fire protection center, laboratory center and central control room have also been put into operation.
Since December, good news has continued for the first phase of the Zhejiang Petrochemical Project, and multiple sets of units have been put into trial operation, heading towards Fully operational and accelerated:
On December 1, Zhejiang Petrochemical’s 4.5 million tons/year heavy oil catalytic cracking unit was put into operation It worked once and is now running smoothly.
On December 2, the world’s largest single reforming unit – Zhejiang Petrochemical 3.8 million tons/year 2# The reforming unit successfully fed materials once and officially entered the start-up stage.
On December 6th and 8th, HDPE and PP granulation trials were successfully completed.
On December 9, the 83000Nm3/h air separation and air pressure device project of the first phase of the Zhejiang Petrochemical Refining and Chemical Project was completed. The oxygen output from the air separation and air pressure device marks that the project is fully put into production and has entered the comprehensive acceptance stage.
On December 15, Everbright Securities’ weekly report on the large refining and chemical industry chain disclosed that Zhejiang Petrochemical’s 3.8 million-ton reforming unit The disproportionation unit has successfully produced qualified pure benzene products, with a daily output of 700-800 tons, and is planned to operate at low load in the short term; the second reforming and aromatics combined unit is planned to be put into operation in early January.
On December 16, the Refining Branch of the Shijian Zhejiang Petroleum Engineering Project Department cleaned up on-site waste and fed materials for the start-up of subsequent units Create safe environmental conditions. Up to now, the second series of residual oil equipment has been put into operation with diesel, and a series of hydrogen gas seals have passed the standard. The next step is to introduce diesel into the equipment; the wax oil equipment has introduced diesel and naphtha, and the next step will be to fully start up the equipment.
On December 16, well-informed sources disclosed that a 2 million tons/year PX unit of Zhejiang Petrochemical has been put into operation. The whole process was cleared up and the first ship of PX was shipped out today!
On December 20, Securities Daily reported that the ethylene and its downstream devices of the first phase of Zhejiang Petrochemical Project have been put into trial production. , qualified products will be produced soon in the near future. According to other sources, the ethylene link of the project is 750,000 tons/year of ethylene glycol and is expected to be produced on the 24th.
Zhejiang Petrochemical’s 40 million tons/year refining and chemical integration project includes a total scale of 40 million tons/year oil refining, 800 10,000 tons/year of paraxylene and 2.8 million tons/year of ethylene, with a total investment of 173 billion yuan. Among them, the first phase of the project, which was officially launched in June 2017, has an investment of 90.156 billion yuan and plans to build 20 million tons/year of oil refining, 5.2 million tons/year of aromatics, and 1.4 million tons/year of ethylene.
The project builder, Zhejiang Petrochemical Co., Ltd., is jointly composed of Zhejiang private enterprises and Zhejiang state-owned assets. The proportion of shareholders is: Rongsheng Petrochemical (002493) invested 51%, Juhua Group invested 20%, Tongkun Investment invested 20%, and Zhoushan Marine Comprehensive Development Investment Co., Ltd. invested 9%.
It is understood that since trial production, the overall operation of the device has been smooth. At present, the main products produced are PX, gasoline and diesel, fuel oil, liquefied gas, etc. At present, the main equipment of the first phase of Zhejiang Petrochemical has been basically completed and has entered the critical period of start-up. Full-process trial production can be started at any time. At the same time, the second phase of the project is also under intensive preparation and construction in parallel. The company plans to strive for the complete delivery of the second phase of the project by the end of next year.
