Abstract:

 This article introduces the circulating fluidized bed oxygen rich pressurized gasification technology used in the coal-based hydrogen production unit of a plant, including the gasification process, the layout plan of main equipment, and the design and stress calculation of related synthesis gas pipelines. The industrialization of this gasification technology has reference significance for the transformation of fixed bed ammonia synthesis, large-scale manufacturing of industrial gas, hydrogen production, and chemical synthesis gas.

Key words: coal-based hydrogen production, gasification unit, equipment layout, synthesis gas pipeline, stress analysis
