This research covered the rate-based process simulation (ProMax^® 4.0) and techno-economic analysis of carbon dioxide (CO₂) capture from a 1.2 million metric tonne per annum cement plant using aqueous 2 kmol/m³ AMP-1 kmol/m³ PZ-2 kmol/m³ MEA blend. The waste gas composition for this study was provided by a cement plant from Quebec, Canada. The effect of amine type, energy penalty, and CO₂ capture efficiency (50% to 90%) on the capture costs (US$/tonne CO₂ and US$/tonne cement) were investigated. Sensitivity analysis on the impact of CO₂ capture plant, carbon tax (US$ 20 to US$ 40 per tonne of CO₂), CO₂ sales price (US$ 10 to US$ 40 per tonne of CO₂), energy penalty and CO₂ capture efficiency on the cement price was also investigated. Results revealed that at 90% CO₂ capture efficiency, the capture costs of AMP-PZ-MEA (US$77.34/tonne CO₂ and US$44.94/tonne cement) is lower than that of MEA (US$93.23/tonne CO₂ and US$54.17/tonne cement). Results also revealed that the total equipment cost and capital expenditure (CAPEX) of MEA system (US$ 29.76 million and US$ 147.12 million) higher than that of AMP-PZ-MEA blend (US$ 23.39 million and US$ 127.59 million).

Cash flow analysis showed that without adding a CO₂ capture unit to a cement plant, carbon tax increased the cement price up to 22.9%. However, a combination of the high carbon tax, high CO₂ sales price, low energy penalty, and high capture efficiency increased the cement price up to 1.2% for the MEA system but reduced the cement price up to 5% for the AMP-PZ-MEA system. This comprehensive study shows that a cost-effective and energy-efficient amine blend, energy penalty, CO₂ capture efficiency, carbon tax, and CO₂ sales prices are all integral towards reducing the cement price while significantly reducing the CO₂ emissions.

本研究覆盖的基于速率的过程仿真（的ProMax ^® 4.0）和二氧化碳的技术经济分析（CO ₂使用）捕获从每年120万公吨水泥厂水溶液2千摩尔/米³ AMP-1千摩尔/米³ PZ-2 kmol / m ³ MEA混合物。这项研究的废气成分由加拿大魁北克的一家水泥厂提供。研究了胺类型，能量损失和CO ₂捕集效率（50％至90％）对捕集成本（美元/吨CO ₂和美元/吨水泥）的影响。对CO ₂捕集装置的影响的敏感性分析，碳税（每吨CO ₂ 20至40美元），CO₂还调查了水泥价格的销售价格（每吨CO ₂ 10至40美元），能量损失和CO ₂捕集效率对水泥价格的影响。结果表明，在90％的CO ₂捕集效率下，AMP-PZ-MEA的捕集成本（77.34美元/吨CO ₂和44.94美元/吨水泥）低于MEA（93.23美元/吨CO ₂和54.17美元）。 /吨水泥）。结果还显示，MEA系统的总设备成本和资本支出（CAPEX）（2,976万美元和14,712万美元）比AMP-PZ-MEA混合物的总设备成本和资本支出（2,339万美元和12,759万美元）高。

现金流量分析显示，在水泥厂不增加CO ₂捕集装置的情况下，碳税使水泥价格上涨了22.9％。但是，高碳税，高CO ₂销售价格，低能耗和高捕集效率的结合使MEA系统的水泥价格上涨了1.2％，而AMP-PZ的水泥价格下跌了5％。 -MEA系统。这项全面的研究表明，在降低水泥价格的同时显着减少CO ₂排放的同时，具有成本效益和能效的胺共混物，能量损失，CO ₂捕集效率，碳税和CO ₂销售价格都是必不可少的。
