A massive quantity of municipal solid waste (MSW) is generated yearly worldwide. The treatment and final disposal of this waste are both financially and environmentally expensive. Also environmentally aggressive, the NH₃ production process releases great amounts of CO₂ in the atmosphere. However, this process is essential for the global economy. In this work, the economic performance of a plant, which combines MSW gasification with the ammonia production process, was studied. The results showed that the project has a low rate of return (0–4%). However, municipalities, which spend billions yearly on MSW treatment, could already benefit from it. The gasifier is the most expensive equipment in the process (approximately 55% of the total installed cost). Refrigeration and electricity are both a burden for the operating cost, accounting for almost 70% of it. Further reduction in the gasifier price and an improved energetic integration could boost the economic performance.

用于环境友好的NH ₃生产的城市固体废物生物精炼厂的初步设计

全世界每年产生大量的城市固体废物（MSW）。这种废物的处理和最终处置在经济和环境上都是昂贵的。NH ₃生产工艺还具有环保优势，可释放大量的CO _2。在大气中。但是，此过程对于全球经济至关重要。在这项工作中，研究了将MSW气化与氨生产过程相结合的工厂的经济性能。结果表明，该项目的回报率很低（0–4％）。但是，每年花费数十亿美元用于城市生活垃圾处理的市政当局已经可以从中受益。气化炉是该过程中最昂贵的设备（约占总安装成本的55％）。制冷和电力都是运营成本的负担，几乎占了运营成本的70％。气化炉价格的进一步降低和能量整合的改善可以提高经济表现。
