Shenwu fog renewable energy efficient use of clean "disruptive technology" was questioned

The 3rd Silk Road International Forum was held in Warsaw, Poland. As a representative of China's energy-saving and environmental protection enterprises, Wu Daodong, chairman of Beijing Shenwu Environmental Energy Technology Group (hereinafter referred to as "Shenwu Group"), was invited to deliver a speech which showed the world 3 fossil fuels and renewable energy Efficient and clean use of "disruptive technologies": acetylene coal chemical new technology, low-rank coal pyrolysis and thermal power boiler integrated energy-saving denitrification process, biomass and other organic solid waste pyrolysis Deal with new technologies.

According to Shenwu Group, "acetylene coal chemical new technology" is the world's first new coal chemical technology, "regenerative calcium carbide production process," as the core, the use of sub-grade coal cascade utilization, the final realization of coal Clean and efficient use.

However, the "disruptive technology" has not been widely recognized by the industry. A number of coal chemical experts believe that "acetylene coal chemical new technology" and "no recirculation methanation new technology," although a certain degree of innovation, but to rise to "disruptive height," is exaggerated.

In response, Du Bin, head of Shenwu Group, said: "We do not think there was anything we have done before. Now that we have done it, we are disruptive." Meanwhile, on June 22, 2016, Shenwu Group replied with a name As a "subversive breakthrough in China's manufacturing energy efficient clean utilization of the bottleneck" and a presentation of Shenwu Group's PPT.

Advantages of new technology to be tested

"After eight years of successful research and development of" no cycle of methanation new technology "to achieve the disruptive innovation of the traditional process, a breakthrough in the elimination of the high temperature circulating compressor, with investment, low energy consumption, good economic efficiency, operating costs Low and stable product quality. "Wang Qinya, general manager of Beijing Huafu Engineering Co., Ltd. (hereinafter referred to as" Huafu Engineering ") of Shenwu Group, has publicly announced the launch of a new high-profile coal chemical technology, At present, the methane plant in China's coal-to-natural gas project mainly relies on the introduction of recycling technology from various foreign manufacturers. Both high-temperature cycle compressors and core equipment and catalysts need to be introduced. The temperature of methanation reaction is not easily controlled, System prone to parking problems.

However, this seemingly obvious advantage of new coal chemical technology, but encountered in the industry widely questioned. A person in the field of coal chemical industry said that in 2009 by the State Council released the "petrochemical industry restructuring and revitalization plan," China's coal chemical industry began to spurt-style development, a large number of coal chemical projects will be followed. However, redundant construction has led to overcapacity.

In June 2010, the state released the "Circular on Regulating Matters Related to the Development of Coal Gasification Industry", tightening the examination and approval authority for coal gas projects to the national level. In March 2011, the National Development and Reform Commission explicitly once again prohibited the construction of coal gas projects with an annual output of 2 billion cubic meters.

This shows that the coal gas project in China is already limited. So, Shenwu Group to serve the coal gas "non-recirculated methanation new technology" how can have much prospect?

In addition, according to a source obtained, Shenwu Group, a new "no-cycle methanation process," has now been applied to Inner Mongolia, the original annual output of 100 million cubic meters of LNG project in Inner Mongolia, Wuhai annual output of 300 million cubic meters SNG project and Xinjiang wins the annual output of 400 million cubic fertilizers SNG project.

In the strict control of coal gas projects, and the state requires annual output of not less than cubic meters under the premise of the above three make use of the Shenwu Group "non-recycling methanation new technology" project, whether it is a coal gas project, Have they obtained the approval procedures of the relevant state ministries?

In this regard, Shenwu Group replied that the above project is not a coal gas project, technology is not a coal gas technology, but the use of coal in the classification of graded cascade, through the pyrolysis of coal containing volatile matter, that is, artificial oil The natural gas is extracted and LNG and SNG are produced during pyrolysis gas generation.

In addition, Xuesen, deputy general manager of Shenwu Group and executive director of Shenwu Energy Saving and Low Carbon Technology Research Institute, said that the above three projects have obtained the compliance approval procedures issued by local governments. He believes that these projects are not coal gas projects, so do not need to obtain the approval of the National Development and Reform Commission procedures. Local governments can directly approve. In addition, Xuesun that modern coal chemical industry is the main card in the gasification.

Unexpected industrialization prospects

In fact, the new technology of "loop-free methanation" is not the first patented technology introduced by Shenwu Group. A person familiar with the Shenwu Group said that the development of the Shenwu Group has never left the technological innovation.

Earlier, Shenwu Group, a subsidiary of Shenwu Group, announced a new approach to "acetylene coal chemical industry." However, according to a number of experts, the essence of this "acetylene coal chemical technology" is the direct preservation and translation of the thermal energy of the pyrochlore to the formation of acetylene. In other words, the acetylene generation step is turned on or off and transformed Thermal energy of the thermoelectric stone, "We also think that this technology is indeed a certain breakthrough." The above said.

However, Shenwu Group said that the new technology, through disruptive technology innovation and "new technology of regenerative calcium carbide production" as its core, can produce large quantities of hydrogen, carbon monoxide, oil and natural gas while producing low-cost acetylene , And then through the complex synthesis of olefins, gasoline and diesel, methanol, natural gas, ethylene glycol, aromatics and other important energy and chemical products. And will be called "acetylene coal chemical industry," a new path.

In fact, calcium carbide PVC (polyvinyl chloride) path has long been there, what new path? Shenwu Group will merge the process that is called a major innovation, based on what? Insiders questioned.

In this regard, the Shenwu Group said that calcium carbide has always been the path of calcium carbide, but the traditional calcium carbide production process in the production process requires the consumption of large amounts of electricity and high-quality blue charcoal, and emit large amounts of emissions of air and dust, dust and other pollutants, calcium carbide The problems of high power consumption, high pollution and high cost of production process have begun to seriously restrict the sustainable development of acetylene chemical industry.

According to Shenwu Group, "acetylene process coal chemical industry" focuses on "regenerative calcium carbide production process" and produces high quality and low-cost acetylene through coal pyrolysis at the same time by-product man-made natural gas, artificial petroleum and syngas, Therefore, low-cost downstream methanol, natural gas, ethylene glycol, PVC and other energy chemical products.
