The reporter learned from the 2nd China New Coal Chemical Industry International Symposium that the "non-cycle methanation technology" independently developed by domestic enterprises not only realized the localization of methanation technology, but also made innovative breakthroughs in traditional methanation technology.
It has improved the competitiveness of China's coal-to-gas market, and explored a technology route with low energy consumption, low investment, low operating costs, and scientifically feasible, which boosted the confidence of the domestic coal-to-gas industry
.
From the perspective of China’s energy structure and development strategy of “rich coal, poor oil, and low gas”, the energy consumption pattern dominated by coal is difficult to change in the short term.
However, this energy consumption structure has brought huge environmental pressures, Effects, atmospheric smog, climate change, etc.
have become problems that need to be solved urgently in today's society.
Coal-to-gas is an important way for the clean and efficient use of coal
.
At present, the methanation device in coal-to-gas projects in China mainly relies on the introduction of the circulation process technology of various foreign patent companies.
All of them need to be equipped with high-temperature circulation compressors, core equipment and catalysts also need to be introduced, and the methanation reaction temperature is not easy to control.
Various problems such as flying temperature and system failure and shutdown have been caused, which have plagued the coal gas industry for a long time
.
The "Cycleless Methanation Technology" was developed by Beijing Huafu Engineering Co.
, Ltd.
in conjunction with Dalian Ruike and China Coal Longhua, which took eight years to develop
.
Wang Qinya, general manager of Beijing Huafu Engineering Co.
, Ltd.
, said that the main innovations of the new process technology are four aspects: no-cycle methanation process, grading adjustment of hydrogen-carbon ratio, high-temperature-resistant methanation catalyst and built-in waste heat boiler methanation reactor.
.
At present, the process technology has passed the 72-hour on-site calibration and scientific and technological achievements appraisal of the pilot plant organized by the China Petroleum and Chemical Industry Federation
.
The process technology has been applied to many projects in Inner Mongolia, Xinjiang, etc.
, and the transformation from research and development to engineering has been realized, laying a strong scientific and technological foundation for promoting the better and faster development of China's coal-to-gas industry
.
Wang Qinya said that in terms of investment and energy consumption, the non-circulation methanation process eliminates the circulating compressor and its supporting plant, pipeline, control and other auxiliary systems.
Compared with the traditional process, it can save more than 20% of investment and save energy consumption.
More than 25%, with a significant cost advantage
.
The expert group organized by the China Petroleum and Chemical Industry Federation with Tsinghua University professor and academician of the Academy of Engineering Jin Yong as the director of the expert committee conducted scientific and technological achievements appraisal on the non-cycle methanation process technology.
The results showed: "This achievement has developed a new type of non-cycle methanation.
The process is highly innovative and has independent intellectual property rights
.
The process saves the investment in circulating compressors and the corresponding energy consumption, has obvious energy-saving effects, has good application prospects, and the comprehensive technical level has reached the international advanced level
.
" "No-cycle methanation The successful research and development of "technology" has opened up a new way for China's coal-to-gas industry
.
It is understood that there are currently more than 30 coal-to-natural gas projects planned in China, with a total production capacity of nearly 200 billion cubic meters.
If all new production capacity adopts the non-cycle methanation process, it will save 11.
2 billion yuan in investment and 2.
7 billion US dollars in foreign exchange.
Operating costs are 2.
9 billion yuan/year, electricity consumption is saved 2.
4 billion kWh/year, and carbon dioxide emissions are reduced by 2.
21 million tons/year
.
At the same time, the process technology can also be widely used in the comprehensive utilization of tail gas for coal pyrolysis, coking, calcium carbide and other industries, finding a new way for the tail gas utilization of traditional coal chemical projects
.
