Regarding the zero emissions claimed by current domestic coal-to-gas projects, Wang Yusuo shook his head in disapproval. Traditional coal gasification technology, such as Lurgi's technology, was used in Germany in the 1930s and 1940s, and then came to the United States. At that time, Lurgi's technology was a technology for converting coal into oil. The key problem of Lurgi technology is sewage treatment, which is also its natural flaw. Wang Yusuo told this reporter that all chemical projects require water, and water will cause pollution. The new domestic coal-to-gas technology now uses less water, has a high methane conversion rate, and is economical. The new coal-to-gas technology can achieve near-zero emissions in the future, which means the discharged water can reach Class II water quality.
In recent years, the technological innovations of some domestic scientific research institutes and enterprises have shown that some new advanced coal gasification technologies are developed directly for the production of methane and for corresponding domestic coal types, such as catalytic gasification, hydrogenation gasification, etc. Technology, when used in coal gasification, whether from theoretical calculations or experimental demonstrations, the overall efficiency can be ten percentage points higher than traditional foreign coal gasification technology, and water consumption and carbon emissions can also be significantly reduced. In terms of efficiency, It shows great potential in terms of emission reduction and coal type adaptability. These technological innovations will greatly promote the clean and efficient utilization of my country's coal resources.
In order to accelerate domestic coal gasification technology innovation and achieve clean and efficient utilization of coal, Wang Yusuo made suggestions
1. Support independent innovation of coal gasification technology and increase investment in research and development and industrial demonstration of new coal gasification technology. First of all, we must combine the characteristics of my country's coal types and continue to support the research and development of a new generation of coal gasification technologies and processes that have strong adaptability to coal types, high gasification efficiency, low water consumption, and small environmental impact. We must also implement the concept of circular economy development and focus on supporting The coal-based recycling production technology that integrates coal gasification with the resource utilization of sewage, sludge, carbon dioxide and other emissions will also effectively encourage the demonstration and application of independent innovative technologies, simplify the approval process of demonstration projects, new things will be done, and in resources, taxation In other aspects, corresponding policy support should be provided to accelerate the industrial application of independent innovation technologies.
2. Clarify the strategic positioning for the development of coal-to-gas production and formulate corresponding mid- and long-term development plans. Coal-to-gas is an important direction for clean coal use and the main application field of coal gasification technology in the future. In order to encourage the research, development and application of innovative coal gasification technology and promote the healthy and orderly development of the coal-to-gas industry.
3. Formulate and continue to optimize the access and supervision standards for the ladder-type industry, and continuously promote the upgrading and development of the coal-to-gas industry. It is necessary to use ~ years as the industry assessment cycle, based on different regional resource characteristics and ecological environment requirements, formulate and gradually increase the thresholds for binding evaluation indicators such as energy efficiency, resource consumption, and environmental impact, and continue to improve industry standards to promote the continuous upgrading of technology and industry , if it cannot meet the requirements, it is better to slow down or even not develop while giving equal attention to project access, operation supervision and evaluation. In particular, it is necessary to increase the supervision and law enforcement during the production and operation stage of coal-to-gas projects, and at the same time strengthen the post-project evaluation work. In order to formulate Ladder-type constraint indicators provide the necessary basis. Finally, based on the actual monitoring of energy efficiency, water consumption, and pollutant emissions after the project is put into operation, differentiated tax collection standards will be formulated to encourage the research and development and application of advanced technologies.
