Happy May Day 2024! Safety first. Let’s give praise and support to the achievements made in China’s chemical engineering technology and equipment. **********************【Ten Years of Progress in Chemical Engineering Equipment】A continuously updated summary post is available; feel free to join the discussions at https://bbs.hcbbs.com/thread-3576046-1-1.html (Source: Haichuan Chemical Industry Forum) ***************** On December 16, 2013, news came from Yutai Gas Company in Handan City, Hebei Province: The industrial facility for converting coke oven gas into compressed natural gas (CNG) with a capacity of 30,000 cubic meters per hour was successfully put into operation. It has been running stably for 12 days now, producing high-quality compressed natural gas that meets the standards required for use by urban residents and in vehicles. The technology for this facility was provided by Southwest Chemical Research and Design Institute Co., Ltd. and Sichuan Tianyi Technology Co., Ltd.; the catalysts were supplied by Southwest Chemical Research and Design Institute, while Tianyi Technology Co., Ltd. was responsible for the engineering design. This is the first industrial facility in our country for producing CNG from coke oven gas, opening up a new way for the efficient utilization of such gas. It holds great significance for alleviating the gas shortage in areas where coke production is concentrated and where natural gas is scarce. The industrial plant for the methanation of coke oven gas to produce compressed natural gas, with a capacity of 30,000 standard cubic meters per hour, which was independently developed and designed by the Southwest Chemical Research Institute and Sichuan Tianke Co., Ltd., has recently come online at Yutai Gas Co., Ltd. in Handan City, Hebei Province. As China’s first facility for producing compressed natural gas from coke oven gas, this project enables annual carbon dioxide emissions reductions of 900,000 tons and an annual production of 100 million cubic meters of natural gas, thus opening up a new pathway in China for converting waste gases from heavily polluting industries into clean energy. Since 2006, the Southwest Research Institute has been conducting research on catalysts and process technologies for the methanation of coke oven gas to produce natural gas. It has completed laboratory studies, pilot tests, and the development of process software packages, filed 10 invention patents, and obtained 5 of them. Its project on \"Pilot production of synthetic natural gas via methanation of coke oven gas and catalyst development\" passed the evaluation organized by the Sichuan Provincial Department of Science and Technology in May 2010, with all indicators exceeding those of domestic and international counterparts, demonstrating significant energy-saving and emission-reduction effects. As one of the key projects for the commercialization of the aforementioned technological achievements, China’s first facility for producing compressed natural gas from coke oven gas, the \"Yutai Gas Coke Oven Gas Methanation Project\", has a total investment of around 200 million yuan and a construction period of 18 months. The plant was successfully commissioned on December 4th after a single batch of material was fed into it. To date, it has been operating stably for 12 days; the product quality meets the standard requirements for natural gas used by urban residents and in vehicle fuel applications. It features an advanced process flow, mature and reliable technology, low energy consumption, and good economic efficiency. Chen Mangui, general manager of Yutai Gas, said that the project will result in an annual reduction of 900,000 tons of carbon dioxide, 726 tons of sulfur dioxide, and 10 tons of dust. It is expected to produce 100 million cubic meters of natural gas per year, generating sales revenue of around 300 million yuan. Currently, the company has successfully sold the first batch of qualified compressed natural gas, and in one month its products will also be fed directly into the gas supply network in Handan City, thereby helping to meet the local demand for gas through multiple channels. A responsible official from the Southwest Research Institute said that China is a major country in the field of coke chemistry. By using the \"methanation of coke oven gas to produce natural gas\" technology to recover the 20 billion cubic meters of coke oven gas that are released each year in China, it is possible to produce around 8.5 billion cubic meters of natural gas. This not only contributes to energy conservation and emission reduction but also holds great significance for the strategy of energy substitution. Currently, the Southwest Research Institute and Tianke Co., Ltd. are collaborating with various entities such as Shanxi Guoxin Chintai and Shanxi Xiangkuang Hengtong on projects related to the methanization of coke oven gas. They have provided technology transfer to over 10 companies and prepared feasibility study reports for more than 30 companies. (Reporter Sheng Li)
