The super-large PSA hydrogen production unit, part of the 1.8 million tons per year ethylene glycol production project under Shaanxi Coal Group Yulin Chemical Company’s demonstration project for the utilization of coal in order to produce new chemical materials, is now undergoing adsorbent loading; it has entered the final preparation stage before commencing operation.
The facility utilizes proprietary technology, comprehensive design, and key equipment provided by Sinochem Southwest Chemical Research and Design Institute Co., Ltd. (Southwest Institute); its total capacity for processing feed gas is 570,000 Nm³/h, with a total hydrogen production capacity of 480,000 Nm³/h. The installation was successfully completed in April this year. After a series of tasks such as purging, airtightness testing, pressure holding, final adjustments, and sequence inspections, the loading of adsorbents began at the beginning of August, with a total amount of 1,676.82 tons of adsorbent being used. As of August 9, most of the loading work has been completed.
The lifting of the PSA equipment took 24 days, with a total of 48 units lifted. The total weight of the equipment was 1,607.80 tons; the heaviest individual unit weighed 59.12 tons and stood 34.5 meters tall. The successful completion of the lifting work for the PSA unit equipment has laid a solid foundation for the subsequent installation of the steel structure and process pipelines.
