Summary of Construction Progress for Zhongan United’s Coal-to-Olefins Project in August: The polypropylene unit has entered the equipment installation phase. Author/Source: Date: 2018-08-30 Clicks: 21. The polypropylene unit has entered the equipment installation phase. Recently, Zhongan United’s polypropylene plant with an annual production capacity of 350,000 tons has entered the equipment installation phase. Among them, the construction work on the six mixing silos, four packaging silos, and two intermediate silos for aluminum-magnesium alloys was fully launched in mid-June. Currently, four silos have been assembled. According to the plan, all twelve silos will have their construction and installation completed by mid-October. The first circulating water facility for the Zhongan United Coal Chemical Project was completed by CCCC on August 28. With this completion, all three circulating water facilities for the Zhongan project have now been built by CCCC, and the circulating water system has moved fully from the construction phase to the production preparation phase. The Zhongan United Coal Chemical Project is equipped with three sets of circulating water systems; the third and second circulating water systems were completed and handed over at the end of June and the beginning of August this year, respectively. The first circulating water plant began construction in early June 2017, with a designed water treatment capacity of 58,500 cubic meters per hour, featuring 6 sets of 13 circulating water towers. In its first cycle water operation, the facility supplies circulating water through two routes: one route supplies water to the olefins, OCC, polypropylene, polyethylene units, the tank farm, and the wastewater treatment plant, while the other route supplies water to production units such as methanol synthesis and sulfur recovery. Successful primary power supply to the substation of the coal transmission and storage facility On the afternoon of August 10, the primary power supply was successfully established for Substation No. 1 in the An’an coal transmission and storage facility area, which is under EPC contract by Sinopec Refining & Chemical Engineering Ningbo Company. All equipment in the substation was started up under powered conditions and is operating safely and normally. To enable the coal transmission and storage substation to receive power at a high level, the company’s project team developed a detailed implementation plan and organizational strategy, breaking down the tasks into specific items and assigning them to individual responsible persons. On-site workers worked overtime, and rigorous technical briefings and process training were conducted ； The head of the electrical team in the EPC project department, along with the electrical commissioning engineers, worked together hard, carefully planning and checking every detail, every circuit, and every button, to ensure a successful power connection on the first attempt. During the power surge, the high-quality construction results and meticulous project planning were highly recognized by the project management department of Zhongan’s owners, as well as the engineering supervision and quality control teams. The successful power supply to this substation provides a solid guarantee for the upcoming individual testing of the coal feeding line for vehicles and for the goal of lighting the boiler on August 30. The second circulating water plant was successfully handed over on the morning of August 7. The second circulating water plant for the Zhongan United Coal Chemical Project, constructed by Sinopec Nanjing Engineering Company, was successfully delivered. The completion of this unit also marks the completion of an important supporting facility for Zhong’an Core’s gasification and purification units, providing a reliable supply of circulating water to ensure the successful commissioning of these units as well as their safe operation in the future. The last large tower for the MTO unit arrived on August 6th; the final large tower of the MTO unit in the Zhong’an United Coal Chemical Project was delivered to the site of the unit. This reaction tower is the oxide stripping tower of the MTO unit; it is approximately 60 meters long and weighs 124 tons. After insulation, process pipelines, and other auxiliary facilities are installed on the ground, the tower will be lifted into place as a whole. The MTO unit is a key component of the Zhongan United Coal Chemicals project; it is responsible for supplying materials for the product production processes in this coal chemicals facility. The completion of this unit is scheduled by the end of the year.
