Ying’s research work mainly focuses on production process modeling, simulation, and optimization. In this work, a conceptual design for a super industrial complex (termed A 3 U) that utilizes natural gas for electricity generation, fertilizer production, and carbon capture has been developed. It integrates four subsystems: air separation, Allam-cycle power plant, ammonia production, and urea production. By efficiently integrating material and energy streams, the A 3 U complex can economically produce net power, urea fertilizer, CO2 , nitrogen, and low-pressure steam. Notably, it boasts low emissions of CO2 and no NOx emissions during manufacturing. The large-scale modeling and simulations demonstrate the economic and environmental benefits, which outperform normal standalone processes.
