Thread Content
On June 9, the cooperation agreement for the coal-based clean gas project in the Fengcheng Ceramic Industrial Park of Jiangxi Province was officially signed. Li Liangshi, General Manager and Party Secretary of Jiangxi Energy Group, Zhang Shenyong, Deputy General Manager, Wu Daohong, Chairman of Beijing Shenwu Group, Qian Xuejie, Deputy Chairman, and other relevant officials were present. It is reported that the total investment in this coal-based clean gas supply project is 1.23 billion yuan; it is capable of supplying 2.5 billion cubic meters of coal-based clean gas per year to the Fengcheng High-End Ceramic Industrial Park. Shenwu Group and Jiangxi Energy Group each hold 50% of the shares in this project. The coal-based clean gas supply project for the Fengcheng Ceramic Industrial Park is a key investment attraction project in Fengcheng City. It represents a model partnership between Shenwu Group and Jiangxi Energy Group, driven by the concept of \"using coal without actually burning it, thereby saving money and protecting the environment.\" The aim of this project is to address various practical challenges related to people’s livelihoods across the country, such as the severe pollution caused by coal use in energy-consuming enterprises, the high costs of using natural gas, heavy losses in the manufacturing sector, and difficulties in utilizing low-quality coal. As a developer of key technologies and equipment for heatless carrier regenerative rotary bed coal pyrolysis, Beijing Shenwu Environmental Energy Technology Group Co., Ltd. is a provider of energy-saving and low-carbon technology solutions for the global fossil fuel consumption market. It specializes in the development and promotion of efficient combustion technologies as well as advanced processing technologies for fossil fuels. Shenwu Group is committed to the research, development, and promotion of industrial energy-saving and emission-reduction technologies as well as technologies for the comprehensive utilization of resources. Leveraging its large-scale research and pilot production base for energy conservation and emission reduction, and through business models of engineering consulting and design as well as turnkey project management, it promotes its independently developed technologies for industrial energy conservation and emission reduction as well as comprehensive resource utilization – such as efficient combustion, direct reduction smelting, upgrading of low-quality coal, oil and gas extraction, and optimization of energy systems – to high-energy-consuming, high-emission industrial enterprises that rely heavily on fossil fuels (coal, oil, natural gas, and their derivatives). Jiangxi Energy Group Company was established at the end of 2014 by renaming the former Jiangxi Coal Group Company; it is a super-large state-owned energy enterprise in Jiangxi. By the end of 2014, the company’s registered capital was 1.6 billion yuan, its total assets amounted to 27.6 billion yuan, and its annual revenue exceeded 20 billion yuan. In 2014, it ranked 446th among China’s top 500 enterprises and 30th among China’s top 100 coal enterprises. The group owns various affiliated enterprises and institutions such as Anyuan Coal Industry Group Co., Ltd., Zhongding International Construction Group Co., Ltd., Jiangxi China Coal Technology Group Co., Ltd., Guizhou Mining Group Co., Ltd., Jiangxi Coal Trading Center, and Jiangxi Mine Emergency Rescue Center. It also has enterprises that have continued to operate after restructuring, such as Pingxiang Mining Group Company, Fengcheng Mining Bureau, Xinyu Mining Company, and Leping Mining Bureau. Among them, Anyuan Coal Industry Group Co., Ltd. is a listed company, while Zhongding International Construction Group Co., Ltd. is among the top 250 largest contractors in the world.
Heat carrier-free regenerative rotary bed? I’ve never heard of it, let alone seen it.
Keqi Company improves the management level of gasification furnaces through “two charts and two tables”. Author/Source: Date: 2015-06-12 Clicks: 12. Keqi Company adopted the “two charts and one table” management approach used in quality control, and adapted it to the specific conditions of its facilities to develop a quality management method that involves Pareto charts, cause-and-effect diagrams, questionnaires, and action plans; this approach has yielded significant results in the daily management of gasification furnaces. To improve the overall operational efficiency of the gasification furnace and ensure a stable supply of raw gas, in April of this year, the gasification plant of Keqi Company held a special meeting to identify the factors affecting performance and formulate solutions, emphasizing the need to use quality management methods to address the existing problems. By using a survey form, the shutdowns of the gasifier since the jacket maintenance in 2014 were counted, and then the frequency of these shutdowns along with their main causes were detailedly listed using a Pareto chart. Once the main cause is identified, a cause-and-effect diagram (Ishikawa diagram) is used to analyze the existing problems from the five aspects of people, machines, materials, methods, and environment. Ultimately, a countermeasure table is developed to address the issues, and solutions are formulated in a planned and targeted manner; by doing so, the problems are eliminated one by one, achieving the goal of long-term stable operation of the gasification furnace. “Through more than a month of practice, certain results have been achieved. At present, all the gasification furnaces are operating continuously and stably, and in terms of production performance, there has been a significant improvement compared to previous months. ”Xia Yongzheng, senior supervisor of the company’s gasification plant, explained. “The ‘two diagrams and two tables’ method employed by the branch plant for quality management aimed at ensuring the long-term stable operation of the gasification furnace is still in the process of improvement; once it has been developed into a mature management approach, it will be applied in the gas and water separation as well as phenol and ammonia recovery units. ”Meng Xiangqing, assistant to the general manager of Keqi Company and director of the gasification plant, said. The coal gasification process is the cornerstone of the entire coal-to-natural gas production process; it undertakes the task of producing raw coal gas and plays a key role in ensuring the stable operation of downstream facilities as well as maintaining the required production levels. Therefore, the long-term stable operation of the gasifier, the core device for producing raw coal gas, becomes of utmost importance. By adopting the quality management method of “two diagrams and two tables”, Keqi Company has seen a significant improvement in the operation and management level of its gasification furnaces, with tangible results achieved. Since last November, the series of gasification furnaces at Keqi Company have been operating stably for more days than at any time in the past, resulting in good economic benefits.
True God! I just started learning about it a bit; from the promotional materials, it seems to be another internationally leading product! What an arrogance – turning an indirect heating mobile pyrolysis bed into something world-class; really has no idea what’s possible. In fact, it’s honest and solid to be an upright person, because one walks on the ground with both feet. Please pay attention to a few issues: 1. To produce more than 60% semi-coke using this process, it is necessary to find a buyer for it; in other words, if you were originally using gas, the coal tar produced as a by-product is not an issue, but what about the semi-coke? If sales are poor, one becomes dependent on others. Of course, the market might accept this process at present because it is small. 2 Can high heat transfer efficiency be achieved when heating solid particles using indirect heating? Can the temperature of particles that are farther away from the heat source increase? Especially large particles, 10-100mm. In fact, a particle layer with voids has excellent insulation properties. 3 Are the pyrolysis consumption indicators advanced? How much gas is needed per ton of coal? Is the smoke clean? 4 How is gas purified? How is wastewater treated? This is similar to the problems encountered in Lurgi gasification. In fact, this process is essentially a pyrolysis process. Whether it’s advanced or not depends on factors such as energy consumption levels, environmental protection standards, and market size. It’s better for everyone to be modest and to do things diligently.
