这项研究的目的是通过技术经济评估证明，苯胺可以用一种比目前使用的工艺更有利可图和本质上更安全的工艺进行工业生产。利用工艺模拟软件对苯胺生产工艺进行了设计。由此，确定了质量和能量平衡，进行了设备尺寸计算，计算出净现值（NPV）为9350万美元。此外，为了提高工艺盈利能力，进行了热集成分析，获得了9750万美元的新净现值。经济敏感性分析表明，该工艺可以承受高达89%的固定资本投资变化，加权平均资本成本变化在16-24%之间，环己胺需求减少高达44%。当苯胺价格在1224-1840美元/t范围内变化，苯酚成本在815-1178美元/t范围内变化时，概念设计仍然是有利可图的。化学工程;化学工业;安全工程;流程建模;计算机辅助工程;苯酚制苯胺；流程设计;过程安全;能量分析;经济评价
The purpose of this research is to demonstrate through a techno-economic assessment that aniline can be industrially produced using a profitable and inherently safer process than the ones currently employed. The aniline production process was designed using process simulation software. From this, the mass and energy balances were determined, the equipment sizing was performed and the net present value (NPV) was calculated to be USD 93.5 million. Additionally, a heat integration analysis was carried out in order to improve process profitability, obtaining a new NPV of USD 97.5 million. The economic sensitivity analysis showed that the process could withstand fixed capital investment changes of up to +89%, weighted average cost of capital changes between 16–24% and a decrease in cyclohexylamine demand of up to 44%. The conceptual design is still profitable when aniline price is varied in a range of 1224–1840 $/t and phenol cost in a range of 815–1178 $/t.
