The roller coal grinding unit is the core equipment of the gasification plant. Each such unit is 11.18 meters tall and weighs 237 tons. It consists of 14 components, including the coal grinder plate, reducer, base, sealing device, drive disc and scraper, casing, grinding ring and nozzle ring, grinding roller assembly, sealing air duct for the grinding rollers, pressure frame and hinge shaft assembly, tie rod loading mechanism, separator, slag discharge box, and explosion-proof steam ducts. From the time the equipment is unpacked and inspected until it is fully installed, a total of 20 installation steps are required.
The first air separation cryogenic tank for Shenhua Ningmei’s coal-to-oil project was successfully delivered. Author/Source: Date: 2015-08-18 Clicks: 12 On August 16, good news came from the site of the coal-to-oil project: the Linde No. 1 cryogenic tank of the air separation unit was mechanically completed. This marks the complete installation of the core equipment for the first air separation unit in the largest cluster of air separation plants under construction, as well as in the coal-to-oil project, which boasts world-leading standards; it has now entered the trial operation preparation phase involving \"three inspections and four determinations\". Linde cryogenic tanks are installed in a cubic configuration, with a penetration rate of high-strength bolts exceeding 92% ; 100% qualification rate for aluminum tube welding ; The cleanliness inside the cold box is 100% controlled ; A total of 78 static equipment units were installed, with a one-time acceptance rate of 99% ; A total of 54 moving equipment units were installed, with a one-time acceptance rate of 98.7% ; The total length of pipeline installation is 11,866 meters, with a first-time acceptance rate of 98.5%. Delivering the cold box in advance can prevent overlapping operations with the construction and installation of subsequent systems and pipe racks, improving on-site installation efficiency and facilitating safe management during installation. The Air Separation Project Department focuses on on-site project construction, takes plans as the guiding principle, and relies on strengthening the \"four key controls\" to advance clean construction methods, soil-free installation techniques, and the \"6S\" management system for large-scale equipment installation. This approach helps to accelerate the installation of subsequent unit cryogenic tanks as well as the commissioning of large-scale equipment.
Shenhua Ningmei: 180 billion yuan to build a world-class coal chemical industry hub. Author/Source: Date: 2015-08-12. Clicks: 31. Shenhua Ningmei is the key player in the development of the Ningdong Energy and Chemical Industry Hub, tasked with building a coal processing facility capable of handling hundreds of millions of tons of coal as well as a modern coal chemical industry hub. Since its construction began in October 2004, the Shenhua Ningmei Modern Coal Chemical Industry Base has seen a total investment of 63 billion yuan to date. Jiao Hongqiao, assistant general manager of Shenhua Ningxia Coal Industry Group Company, said that by 2017, the coal chemical sector was expected to have seen a total investment of 104 billion yuan. The production capacity for polyolefins would reach 2 million tons, oil products 3.2 million tons, dimethyl ether 210,000 tons, polyoxymethylene 60,000 tons, sulfuric acid 200,000 tons, and sulfur 200,000 tons. The annual coal consumption would be around 35 million tons, with annual revenue exceeding 43 billion yuan. By then, the Shenhua Ningxia Coal Chemical Industry Base will become the largest coal chemical industry base in the world, with the strongest competitive advantages and the greatest potential for development. By 2020, it is planned that the base will have achieved a total investment of 180 billion yuan; its production capacity for coal-based dimethyl ether will reach 210,000 tons, polyoxymethylene production will amount to 60,000 tons, coal-based olefins production will be 3 million tons, and coal-to-oil production will be 6 million tons. Nearly 60 million tons of raw coal will be converted on-site each year, with the total output value exceeding 75 billion yuan. Such large-scale investments in coal chemical industries have also given rise to a range of issues related to environmental protection. Jiao Hongqiao said that, compared with other domestic coal-to-oil chemical enterprises, Shenhua Ningmei attaches great importance to environmental protection throughout the project planning, construction, and production operation phases. It aims to build an environmentally friendly enterprise and transform the already established Ningdong Coal Chemical Industry Base into a distinctive coal chemical industry park that combines an industrial production demonstration area with a circular economy demonstration area. Shenhua Ningmei utilizes advanced domestic wastewater treatment technologies such as CAST, SBR, BAF, and UASB, as well as cutting-edge processes like SCR, SNCR, wet flue gas desulfurization outside the furnace, and super Claus sulfur recovery. The flue gas from boilers used in projects such as methanol and olefins that have already been built was modified to remove sulfur and nitrogen oxides. In line with the **\"zero emission\" requirement**, efforts were made to promote clean production and energy conservation, thereby achieving initial progress toward green development within the industrial park. To date, the Shenhua Ningmei Modern Coal Chemical Industry Base has completed six large-scale modern coal chemical projects, including ones with an annual production capacity of 250,000 tons of methanol, 210,000 tons of dimethyl ether, 600,000 tons of methanol, 500,000 tons of coal-based olefins, 60,000 tons of polyoxymethylene, and 500,000 tons of olefins produced from methanol. The production capacity of the facility is 2.52 million tons of methanol, 1 million tons of polypropylene, 368,000 tons of mixed aromatics, 81,200 tons of LPG, 60,000 tons of polyoxymethylene, and 210,000 tons of dimethyl ether per year. Analysis of the status of projects already completed: The 500,000 tons per year coal-based olefins (MTP) project commenced operations in October 2007, and qualified polypropylene products were produced in December 2010. This project is the world’s first large-scale coal chemical complex that uses coal as raw material to produce polypropylene plastics through a process involving coal gasification (000968, stock forum) for methanol production, conversion of methanol into propylene, and then polymerization of propylene. The gasification unit utilizes Siemens’ GSP dry coal powder gasification technology, the MTP unit employs the Lurgi process technology, while the PP unit uses Ruems’ patented technology. The 500,000 tons per year methanol-to-olefins project commenced construction in March 2011, and the plant reached full production capacity in September 2014. The project produces polypropylene plastic through the process of converting methanol into olefins, followed by the polymerization of those olefins. The methanol-to-olefins technology for this project utilizes LyondellBasell’s MTP process, while the polypropylene process employs the RuMS process. The 4 million tons per year coal indirect liquefaction demonstration project was approved by the National Development and Reform Commission on September 18, 2013, and construction commenced in full on September 28. Line A for coal-to-oil production was scheduled to begin trial operation in September 2016, while Line B was set to start trial operation in April 2017, entering commercial operation in October 2017. The project for the deep processing and comprehensive utilization of coal chemical by-products with an annual capacity of 1 million tons began construction in October 2013, with plans to be put into operation simultaneously with the coal-to-oil project. The project is a chemical facility that uses naphtha (983,000 tons per year) and liquefied petroleum gas (415,000 tons per year), which are by-products of coal-to-oil projects, coal-to-olefins projects, and methanol-to-olefins projects, as raw materials (with a total feed volume of 1.4 million tons per year). Through cracking to produce ethylene and propylene, followed by olefin polymerization, it manufactures polyethylene and polypropylene plastics. In short, after a decade of development and construction, the Shenhua Ningmei Coal Chemical Industry Base has become the largest coal chemical industry base in the country. In addition to the 6 projects that have already been completed, the Shenhua Ningmei Modern Coal Chemical Industry Base is also constructing 3 more projects: one for coal indirect liquefaction with an annual capacity of 4 million tons, one for the comprehensive utilization of coal slime, and one for the deep processing and comprehensive utilization of by-products from coal chemical production.
