A new configuration to convert the traditional ammonia synthesis plants into an environmentally benign process is proposed in this study. The proposed design is implemented by integrating three different types of natural gas reforming for clean hydrogen, methanol and ammonia synthesis. The solar heat source provides the absorption cooling unit with heat and natural gas reformers with steam. The CO₂ emissions released by the natural gas reforming configuration reacts with hydrogen for methanol synthesis. A pressure swing adsorption unit separates oxygen for natural gas autothermal reforming and nitrogen for ammonia synthesis. A part of hydrogen produced by the natural gas reforming unit is designed to pass through a double-stage ammonia production reactor for ammonia synthesis. The proposed configuration yields 10 mol/s of H₂ and 2.4 mol/s of NH₃. The overall system energetic and exergetic efficiencies are found to be 66.83% and 68.55%. The present system yields 13.31 mol/s of CH₃OH and 625.9 kW of cooling. Moreover, numerous sensitivity analyses are conducted on the proposed configuration and its performance assessment.

在这项研究中提出了一种将传统的氨合成厂转变为对环境有益的工艺的新配置。通过整合三种不同类型的天然气重整来清洁氢气，甲醇和氨的合成，实现了拟议的设计。太阳热源为吸收式冷却装置提供热量，天然气重整器提供蒸汽。一氧化碳₂天然气重整装置释放的废气与氢气反应生成甲醇。变压吸附单元将用于天然气自热重整的氧气和用于氨合成的氮气分开。天然气重整单元产生的一部分氢气被设计为通过用于氨合成的双级氨生产反应器。提出的构型产生10 mol / s的H ₂和2.4 mol / s的NH ₃。整个系统的能量和能量效率分别为66.83％和68.55％。本系统产生13.31mol / s的CH ₃ OH和625.9kW的冷却。此外，对提议的配置及其性能评估进行了许多敏感性分析。
