On August 13th, the reporter learned from Shenhua Group that a pressure swing adsorption gas separation (PSA) hydrogen production plant that handled a gas volume of 340,000 Nm3/hr was successfully tested at one time and all technical indicators met the design requirements and will be in the group. The coal oil project plays a central role. This is currently the world's largest PSA hydrogen production plant. Many of these processes use technology and processes that were first adopted in the world, breaking the monopoly of foreign companies over the years in large PSA hydrogen production plants.
According to reports, before that, the largest PSA hydrogen plant installed abroad had a processing gas volume of 236,000 standard cubic meters per hour, while the largest domestic PSA hydrogen production plant capacity was only 75,000 standard cubic meters per hour.
According to Wang Heming, deputy general manager of Shenhua Group's Coal-to-liquids Co., Ltd., the Shenhua Group's coal-to-oil project is a national key project approved by the State Council and is the world's first commercial demonstration unit for direct liquefaction of coal. Hydrogen is the leader of the coal-to-oil project, and the hydrogen production unit is the core of the entire project. The PSA hydrogen production device can convert the coal powder provided by the coal preparation device into a synthesis gas through a partial oxidation method, and then it is processed into a high-purity product hydrogen through transformation, pressure swing adsorption, and the like.
The world's largest PSA hydrogen production plant is designed and manufactured by Sichuan Tianyi Technology Co., Ltd. This device not only ranks first in the world, but also rewrites history in terms of process design, process flow, special valves, adsorbents and many other aspects. For example, in terms of process design, the dual-cassette tank operation process with independent intellectual property rights is adopted, which makes the process flow simpler, the operation more stable, and the product yield higher. There is no precedent at home and abroad; the process flow is for the first time using 12 towers. , 4 grouping process, and in the process of switching for the first time to achieve any of the 12 towers to 6 towers between the switch, simplifies the program, the control system to run more smoothly; the use of new sealing technology to ensure that all 172 valves to achieve zero leakage; The use of a new air flow distributor further enhances the use efficiency of the adsorbent. At the same time, according to the characteristics of high requirements for coal-to-oil projects, the device also solves the problem of the existing adsorbent particle size, reduces the dead space, and improves the understanding of the suction rate and the hydrogen yield. The data shows that the device has a processing gas volume of 340,000 standard cubic meters per hour, a hydrogen production capacity of 280,000 standard cubic meters per hour, a hydrogen purity of 99.9%, and a hydrogen yield of not less than 90%.
