Author/Source: Date: 2017-07-24. Views: 20. Recently, the polyethylene production unit of the second phase of Shenhua Ningmei’s coal-to-oil project, with an annual production capacity of 450,000 tons, reached full operational capacity; it began operating at 20:50 on July 19； At 23:55, qualified polyethylene pellets were produced. On May 6, 2017, the extruder of the polyethylene plant was successfully commissioned. At 20:50 on July 19, the main catalyst was added; a reaction was observed after 10 minutes ； At 23:55, the polyethylene unit in the polymerization workshop produced qualified pellets, marking the completion of the entire production process for this unit. The plant utilizes Univation’s Unipol gas-phase fluidized bed polymerization process, and is designed to produce 450,000 tons of full-density polyethylene per year. The foundation design, detailed design, and procurement services for this facility are undertaken by Sinopec Ningbo Engineering Co., Ltd. On April 30, 2017, the ammonia synthesis unit of the project completed its initial commissioning successfully, producing liquid ammonia of 99.6% purity that met the required standards. On March 29, 2017, the first unit of the Olefins Phase II project – the polypropylene plant – also succeeded in its initial trial run, yielding polypropylene pellets that met the specified quality requirements. The Shenhua Ningmei Light Hydrocarbons Project uses naphtha and LPG, which are by-products of coal-to-oil and coal-to-olefins processes, as raw materials; it employs cracking technology to produce ethylene and propylene, and through polymerization the final products are polypropylene and polyethylene ； Benzene, toluene, and mixed xylene are produced using the aromatic extraction process. Ultimately, 580,000 tons of polypropylene, 450,000 tons of polyethylene, 64,000 tons of butadiene, 59,000 tons of mixed benzene, and 150,000 tons of synthetic ammonia can be produced annually. Construction of the project began in September 2014, with a total investment of 12.981 billion yuan. It is planned to complete the entire process by 2017 and enter commercial operation. The second phase of the olefin production unit in Shenhua Ningmei’s coal-to-oil project was completed simultaneously with the 4 million tons per year coal indirect liquefaction project, and the two operate together. This is one of the key projects aimed at extending the coal-to-oil chemical industry chain and increasing the added value of products; it holds great significance for maximizing the profitability of Shenhua Ningmei’s coal-to-oil chemical business unit, as well as for helping the group overcome challenges and achieve transformational development.
