  • Publication number: 20250109028
    Abstract: A propane dehydrogenation and ammonia synthesis coupling system and process. By means of coupling a propane dehydrogenation reaction byproduct, i.e., hydrogen, and high-purity hydrogen required in an ammonia synthesis reaction as a raw material, liquid ammonia can be co-produced as well as a high-quality propylene product being produced. A hydrogen-containing tail gas, which is separated from the propane dehydrogenation reaction, only needs to undergo a simple pressure swing adsorption process to obtain high-purity hydrogen, such that the operation process becomes simple, and the energy utilization efficiency is improved.
