Happy May Day! Reply reward! ---------------------------------------------- The past decade has been a period of rapid development in China’s chemical industry, marked by the emergence of many new processes, products, and equipment. There has also been significant progress in China’s chemical processing equipment, which has contributed to the swift advancement of the petrochemical sector. Here, we have compiled some of the achievements and breakthroughs made by Chinese equipment manufacturers in terms of larger-scale production and greater use of domestic equipment. We invite everyone to share their insights and engage in discussions, to cheer for Made in China and to support the development of chemical processing equipment! ****************** A regular container can hold a hydrogen production station. Once such hydrogen production devices are installed in existing hydrogen refueling stations, hydrogen can be produced and sold on-site, reducing costs by around 50%. Doesn’t such a scenario sound wonderful? This vision could become a reality in the near future. On March 26, Southwest Chemical Research and Design Institute Co., Ltd. signed a strategic cooperation agreement with Sichuan Jinxing Clean Energy Equipment Co., Ltd.; the two parties will engage in extensive and in-depth collaboration on the research, development, and manufacturing of modular skid-mounted pressure swing adsorption hydrogen production equipment. As the **Research and Promotion Center for Pressure Swing Adsorption Gas Separation Technology**, Southwest Chemical Engineering Research and Design Institute Co., Ltd. is at the leading level in China in terms of the research and development of hydrogen production equipment in fields related to hydrogen utilization such as natural gas-based hydrogen production and the construction of hydrogen refueling stations. The pressure swing adsorption technology used this time features a wide range of applicability and low energy consumption. “A variety of mixed gases can be separated, with energy consumption being only half or even less than that of other hydrogen production methods. ”Chen Jian said. Another keyword is “module skid”. In simple terms, it involves making large hydrogen production plants smaller and more modular. It is said that the adsorption towers in typical hydrogen production plants can be arranged over thirty to forty meters in length, making them quite large in size. Venus Company’s modular hydrogen production equipment is just over 10 meters long and 3.7 meters wide, and can be transported in a single container. “Moreover, the production cycle is short, usually around 3 months; some smaller hydrogen production facilities can even be completed in just 1 month. ”said Liu Ge, chief engineer of Sichuan Jinxing Clean Energy Equipment Co., Ltd.
It is understood that large hydrogen production plants currently produce around tens of thousands of cubic meters of hydrogen per hour, while these small hydrogen production units generate about 200 kilograms of hydrogen per hour, which is sufficient to supply a hydrogen refueling station to refuel around 20 buses per hour. “The biggest advantage is the reduction in transportation costs. ”Chen Jian said that since the hydrogen at hydrogen refueling stations is produced and sold locally, the cost can drop from 40 yuan per kilogram to 20 yuan, which will play a significant role in promoting the use of hydrogen-powered vehicles. In June this year, the first skid-mounted hydrogen production unit developed through their collaboration will be delivered for use at a hydrogen refueling station in Foshan, Guangdong, and deliveries of 7 more units will be completed within the same year. “Foshan introduced 1,400 hydrogen-powered buses last year, but 1,000 of them remain idle due to a shortage of hydrogen. ”A relevant official from Southwest Chemical Research and Design Institute Co., Ltd. said.
It is understood that this set of equipment was jointly developed by CNOOC Gas & Power Group Co., Ltd. (hereinafter referred to as CNOOC Gas & Power Group), Southwest Chemical Research and Design Institute Co., Ltd. (hereinafter referred to as Southwest Chemical), and Foshan Fuel Energy Group Co., Ltd. (hereinafter referred to as Foshan Fuel Energy). It features an integrated skid-mounted design, making it easy to install and move. At the same time, this set of equipment has been optimized for the characteristics of hydrogen refueling stations, enabling the immediate production of fuel hydrogen for proton exchange membrane fuel cell vehicles; it thus provides a localized hydrogen supply solution for the development of China’s first batch of fuel cell vehicle demonstration city clusters ； Furthermore, this set of equipment boasts the following advantages: its key device, the new-type conversion furnace, is compact in size, features high efficiency in high-temperature conversion, and has a wide range of applicability ； Conversion and transformation catalysts feature high selectivity and strong activity, enabling them to meet the requirements of frequent adjustments in equipment load ； The intelligent control system enables “one-click start/stop” and “one-click load adjustment”” ； The equipment boasts high overall efficiency and is fully domestically produced; various parameters such as system consumption, equipment size, and product purity are all at world-leading levels ； The highly integrated design of these devices results in a small footprint, which makes it possible to convert or expand existing city gas stations and natural gas facilities into hydrogen production and refueling stations. This approach can effectively address the challenges associated with the limited availability and high cost of hydrogen in urban areas in China. Moreover, this system can draw gas from urban natural gas pipelines and produce hydrogen using an on-site natural gas steam reforming process; there is no need to transport hydrogen to the station via long-distance tankers from centralized hydrogen production facilities. This approach helps to reduce the cost of hydrogen for end-users and minimize the risks associated with road transportation. In addition to achieving self-sufficiency, it also enables the supply of hydrogen to conventional hydrogen filling stations.
Pressure swing adsorption has become a trend in Sichuan; the technology is developing very rapidly. Keep up, chemical industry workers!
Yes, it changes the traditional gas separation method
Guys, I have a question – is there anyone who needs steel grating? ?
