Happy New Year 2024 **********************【A Decade of Rapid Development in Chemical Processing Equipment】Regular updates and summaries are available; feel free to join the discussions at https://bbs.hcbbs.com/thread-3576046-1-1.html (Source: Haichuan Chemical Industry Forum) *****************According to a report from the Urumqi correspondent office of Science and Technology Daily on February 27, China’s Yaxin Coalbed Methane Investment and Development Co., Ltd. recently carried out an in-situ gasification experiment on coal seams located at a depth of one kilometer in Xinjiang, and the initial ignition of these coal seams was successful. The UCG trial, a major scientific and technological project in the autonomous region undertaken by Xinjiang Yaxin Coalbed Methane Investment and Development (Group) Co., Ltd. (hereinafter referred to as “Yaxin Coalbed Methane Group”), was successfully ignited on the first attempt. This approach enabled the simultaneous extraction of both gas and coal from difficult-to-extract coal resources, and it represents a pioneering technique on a global scale. “The “dual-gas extraction” technology enables the extraction of natural gas from coal seams, as well as coal gas at the same time, thereby greatly improving the efficiency of utilizing coal resources. The reporter learned that the UCG test represents a key technical challenge that needs to be addressed as part of the major scientific and technological project undertaken by the Autonomous Region’s Department of Science and Technology, namely \"Advanced Technologies for the Efficient Development of Coalbed Methane Resources in Xinjiang’s Difficult-to-Extract Coal Deposits\". Launched in April 2023, this project focuses on overcoming the key technical challenges related to the clean and efficient use of coal (underground coal gasification) as well as the development of coalbed methane. Through long-term fundamental research and practical engineering efforts, the research team has successfully overcome the limitations of traditional ignition techniques, achieving successful ignition on a single attempt, which lays a solid foundation for the large-scale industrial demonstration of coal underground gasification. Wei Bo explained that the project has also achieved in-situ gasification of coal seams over a thousand meters thick, and this successful breakthrough in such technology is the first of its kind in China. The construction of a super-large wellless underground gasification furnace is also the first of its kind in the country. These innovative achievements demonstrate Yaxin Coalbed Methane Group’s outstanding capabilities in scientific and technological research and development. In this UCG test, the calorific value of the air-gas mixture averaged over 2,500 kilocalories per cubic meter, with peaks reaching up to 4,000 kilocalories per cubic meter; the results thus reached a leading level both domestically and internationally. This increase in calorific value will provide stronger support for the clean use of energy. “The successful one-time ignition of coal in-situ gasification and the ‘co-extraction of two gases’ technology represent an important breakthrough for China in the field of energy, and they are also a milestone in the global clean energy revolution. This achievement will not only bring substantial economic benefits to enterprises, but it will also have a positive impact on **energy security and environmental protection. ”Wei Bo said that in the future, Yaxin Coalbed Methane Group will actively promote the industrial development of coalbed gasification.
