[Ten years of major development in chemical technology] 152-2023 Chongqing Huafeng 60000Nm3/h shale gas hydrogen production unit successfully started up in one go

Thread Content

Chemical science and technology has developed greatly in the past ten years, praising the prosperity of China in the prosperous world. It is more lively and more exciting with everyone's participation. Everyone is welcome to participate in the forum to communicate and discuss, and pay attention to fire prevention. On May 13, 2023, the Chongqing Huafeng 60000Nm3/h shale gas hydrogen production unit, which was contracted by Southwest Chemical Research and Design Institute Co., Ltd. (hereinafter referred to as Southwest Institute), was successfully started at one time and successfully produced qualified product hydrogen. This device is an important part of the adipic acid expansion project (Phase 6) of Chongqing Huafeng Chemical Co., Ltd. It adopts the natural gas steam reforming process and pressure swing adsorption hydrogen separation process with independent intellectual property rights of Southwest Research Institute, and Southwest Research Institute provides key steam reforming catalysts, desulfurizers, adsorbents and pressure swing adsorption special program-controlled valves. Since the project was signed in March 2022, Southwest Research Institute has carefully organized the project team and carried out design, procurement, construction and other work intensively. Construction began in July 2022. During the period, various difficulties were encountered. The project team members were united, cooperated closely, and managed meticulously, ultimately ensuring that the project maintains quality and quantity, and completes all stages of tasks on time. The project was ignited on May 8 and produced hydrogen on May 13. It is the first start-up unit among the many units of the Chongqing Huafeng Phase 6 expansion project, which is a good start for the smooth start-up of the entire Phase 6 expansion project! At present, the device is running smoothly, and all important indicators have reached the leading domestic level. The hydrogen produced has been integrated into the hydrogen pipeline network of the entire plant. The load will be gradually increased in the future to reach the design load of 60,000Nm3/h.
