The 3,000-ton OMB multi-nozzle opposed coal gasification furnace was successfully lifted at Lunan Chemical Industry. Author/Source: Gasification World. Date: April 24, 2023. Clicks: 15. On April 22, the 3,000-ton OMB coal gasification furnace, which is a key piece of equipment in the energy-saving and carbon-reduction integrated project related to the caprolactam production chain of Yankuang Lunan Chemical Industry Co., Ltd. (referred to as “Lunan Chemical Industry”), was successfully lifted for the first time. This marks the achievement of a milestone in the project’s development, with the construction now entering a phase of intensive installation work. The project was constructed by China Tianchen Engineering Co., Ltd. As the core equipment of the project, this gasification furnace is also the heaviest device on site; its total lifting weight is 520 tons and the lifting height is 102 meters. The lifting crane used for this operation is a SCC19000TM 1600-ton crawler crane as the main lifting device, along with an XGC400-1 400-ton crawler crane for assisting with the lifting process. The lifting rigging consists of compressed steel wires with a diameter of 220 mm. Developed jointly by Shandong Energy Group and East China University of Science and Technology, the world’s first 3,000-ton-class OMB multi-nozzle opposed coal gasification furnace with independent intellectual property rights can increase the carbon conversion rate by over 10% compared to existing coal water slurry gasification technologies. It boasts technical advantages such as wide adaptability to different types of coal, low consumption, and ease of scaling up, enabling further improvement in coal utilization efficiency and reduction of carbon emissions. The equipment was manufactured by Dongfang Boiler of Dongfang Electric Corporation. On April 9, the gasifier was delivered to the construction site. The 3,000-ton/day new type of powder coal gasifier is part of the energy-saving and carbon-reduction integrated project developed as part of Lunan Chemical’s caprolactam production chain. The OMB multi-nozzle powder coal gasifier will replace the existing Texaco gasification unit on site, along with supporting facilities for shift conversion, gas purification, synthesis, wet acid production from waste gases, and liquid carbon dioxide production. The integrated project will also carry out expansion and renovation of the 300,000-ton caprolactam plant, increasing its caprolactam production capacity to 400,000 tons per year. The total investment in the integrated energy-saving and carbon-reduction project for the caprolactam industry chain is 2.671 billion yuan. Construction began in May 2022, and it is now in the equipment installation phase, with trials scheduled to take place by the end of the year. This project is a high-chain engineering initiative for caprolactam, and it also serves as an industrial demonstration facility for OMB’s multi-nozzle opposed coal gasification technology. Once completed and put into operation, it will enable the improved utilization of lower-grade coal, filling the gap in China’s technology for gasifying low-quality feedstocks. It holds great significance as a model for the upgrading of chemical production facilities in regions such as Shaanxi-Mongolia and Xinjiang under Shandong Energy Group, as well as for achieving cleaner and more efficient production processes.
