Shi Chongzhuang develops core equipment for Shanghai Huayi POX project, achieving 100 days of stable operation

Thread Content

On November 4th, the three conversion furnaces and waste heat boiler systems that form the core of the Shanghai Huayi syngas supply and supporting project, designed and manufactured by Lansi Heavy Equipment, have been operating safely and stably for 100 days since their successful commissioning in July this year. This demonstrates Lansi Heavy Equipment’s technical excellence and operational reliability in the fields of POX (non-catalytic partial oxidation) waste heat boilers and conversion furnaces, setting a benchmark in the domestic market. The project utilizes natural gas non-catalytic partial oxidation technology with a carbon dioxide recycling system; the conversion process is achieved through internal heating resulting from oxidation reactions, without the need for external heating or catalysts. The decarbonized CO2 is then recycled back to the POX conversion furnaces for reuse, ultimately producing syngas (CO and H2) with zero carbon emissions, thus meeting the requirements for efficient and intensive use of resources. It represents a technology for the recovery and utilization of high-value components from waste gases. Lansi Heavy Equipment was responsible for the research, development, design, and manufacturing of the three conversion furnaces and waste heat boilers in the upstream POX unit, as well as one two-stage furnace and waste heat boiler in the downstream DRM (dry methane reforming) unit. Facing harsh conditions such as extreme temperatures and high pressures during the gas conversion process, Lansi Heavy Equipment successfully overcame various technical challenges related to process calculations, structural design, and complex manufacturing processes. After 12 months of intensive work, all design and manufacturing tasks were completed successfully. To date, the upstream POX conversion furnaces and waste heat boilers have been operating stably for 100 days, while the downstream DRM unit has also been delivered successfully
