This study reports on a gas-phase photocatalytic microreactor (MR) employed for the degradation of 2-propanol in indoor air. A process flow diagram was developed and simulated in Aspen Hysys V10, and a techno-economic assessment was carried out based on the simulated results. An economic evaluation was carried out using a fixed and demand-dependent variable cost model. Decreasing the mass flow rate or the initial concentration of the 2-propanol in indoor air and increasing the diameter or length of the MR resulted in a better air remediation efficacy. Sensitivity analysis for the economics of the manufactured MR showed that the optimal plant production volume is 10,000 units per year. At this volume, the total manufacturing cost was 2.8 M$/y with a production cost of $ 127 per unit and a levelized cost of a MR (LCOM) of about $ 280 per unit. These findings herein can help bolster research into both technical and economic aspects of MR production for the photocatalytic remediation of air. The resulting design could be applied in air conditioner units and other home ventilation units for the removal of harmful volatile organic compounds in the air.
本研究报告了一种用于降解室内空气中2-丙醇的气相光催化微反应器（MR）。绘制了工艺流程示意图并在Aspen Hysys V10中进行了模拟，并基于模拟结果进行了技术经济评估。使用固定成本和与需求相关的可变成本模型进行了经济评估。降低室内空气中2-丙醇的质量流量或初始浓度，以及增加微反应器的直径或长度，可带来更好的空气修复效果。对制造的微反应器经济性的敏感性分析表明，最佳工厂产量为每年10,000台。在此产量下，总制造成本为每年280万美元，单位生产成本为127美元，微反应器的平准化成本（LCOM）约为每台280美元。本文的这些发现有助于加强对用于空气光催化修复的微反应器生产技术和经济方面的研究。所得设计可应用于空调机组和其他家庭通风设备，以去除空气中有害的挥发性有机化合物。
