What are the grade specifications for the products of the world’s largest coal-to-olefins project? Author/Source: Date: 2018-02-01 Clicks: 2 The Zhongtian Hechuang Ordos Coal Chemical Project is a world-class large-scale coal-chemical complex jointly developed by Sinopec Corporation, China National Coal Energy Group Corporation, Shenneng (Group) Co., Ltd., and Inner Mongolia Manshi Coal Group Company. The main entity behind this project is Zhongtian Hechuang Energy Co., Ltd., which was established by these four companies together. The project utilizes the S-MTO technology developed through a collaboration between Sinopec Refining & Chemical Engineering and PetroChina Co., Ltd. The total production capacity of the chemical engineering design is 3.6 million tons per year of methanol (an intermediate product), as well as 1.37 million tons per year of polyethylene and polypropylene plastic products. On April 27, 2017, the tubular polyethylene plant was successfully commissioned with a single batch of feed. On August 6, 2017, the batch-type polyethylene plant was also successfully commissioned with a single batch of feed. In July 2017, the project entered full commercial operation. At 12:56 on August 16, 2017, the MTO unit No. 1 was successfully fed with methanol. At 20:25 on August 16, 2017, the cold separation unit of the olefin separation plant produced qualified ethylene product. Information and grades related to the Zhongtian Hechuang project: The LDPE plant consists of two units – an LDPE plant with a capacity of 120,000 tons per year (batch-type) and an LDPE plant with a capacity of 250,000 tons per year (tubular type). There are 2 pelletizing machines and 5 packaging lines in this plant. Both units are single-line and utilize EXXONMOBIL technology. http://img.yf116.cn/image/img/20180201/105373633787.jpg Full-density PE plant: The full-density PE plant utilizes Sinopec’s gas-phase polyethylene production technology (referred to as SGPE technology), with an annual production capacity of 300,000 tons of polyethylene. The main raw materials used are ethylene, butylene, or hexene. Full-density polyethylene resins with a density range of 916–965 kg/m3 can be produced. The products are applicable to areas such as films, hollow blow molding, injection molding, monofilaments, pipes, and cables. This device’s product lineup includes **11 different grades in total: 7 for membrane materials, 2 for injection-molded plastics, and 2 for tube materials. All of these are products with excellent performance and market viability. http://img.yf116.cn/image/img/20180201/10628363886.jpg PP plants: There are 2 sets of PP plants, including a polypropylene plant with an annual capacity of 350,000 tons (ring-type) and another polypropylene plant with an annual capacity of 350,000 tons (gas-phase). Methanol is synthesized from coal as a raw material; ethylene and propylene are produced through the conversion of methanol, which in turn leads to the manufacture of various grades of polyethylene and polypropylene products. http://img.yf116.cn/image/img/20180201/107163643612.jpg By the end of 2017, the polyethylene resin PE-L18D2(EGF-35B) and polypropylene resin PPH-T03(T30S) produced by Zhongtian Hechuang Chemicals met all the test requirements set by the FDA and other relevant standards. This indicates that these two product grades manufactured by the chemical division have passed authoritative tests and certifications such as those required by domestic health standards and the U.S. FDA, with their quality meeting the requirements for food-grade packaging materials. It is understood that the FDA (Food and Drug Administration) is one of the executive agencies established within the Department of Health and Human Services (DHHS) and the Public Health Service (PHS) in the United States; its role is to ensure the safety of foods, cosmetics, drugs, biological products, medical devices, and radiation products that are produced or imported into the United States. FDA testing methods are testing methods established by the U.S. Food and Drug Administration. Internationally, the FDA is recognized as one of the largest food and drug regulatory agencies in the world. Any containers or materials that come into direct contact with food and beverages, or that come into direct contact with people’s mouths, must meet FDA standards for safety and environmental protection; only after passing such tests and certifications can they be brought onto the U.S. market, as this is crucial for ensuring the safety and health of consumers. FDA certification is not only the highest level of certification in the United States, but it is also the highest recognized certification for food and drugs under the WTO! It has an extremely huge influence worldwide and is known as the \"guardian of Americans’ health.\" The testing conducted by Zhongtian Hechuang was carried out by SGS Standard Technical Services (Tianjin) Co., Ltd., in accordance with the FDA 21CFR 177.1520 standards for food-grade polyethylene (PE) and food-grade polypropylene (PP), as well as standard GB 4806.6-2016 \"Food Safety Standards – Plastic Resins for Food Contact.\" The approval from the FDA has laid a solid foundation for the company to expand its sales of polyolefin products and enhance the reputation of its polyolefin product brand, while also opening up avenues for the company’s food-grade polyolefin packaging materials to enter international markets. Zhongtian Hechuang will continue to carry out this certification process for products of other grades in the future.
