Abstract

Post-combustion carbon capture (PCC) is essential for reducing CO₂ emissions from fossil-fuel-based power generation, but its high energy demands raise important environmental concerns. This study evaluates the environmental performance of seven diglycolamine (DGA)-based PCC configurations implemented in a natural gas combined cycle power plant, using the ReCiPe 2016 Endpoint (H) method in SimaPro. Configurations include six entirely plant-powered designs and one solar-powered system. The Lean Vapor Compression (LVC) configuration achieved the best overall performance, reducing the total impact score by 48 % compared to the Standard configuration (from 3.38 to 1.75 milliPoints per kilowatt-hour, mPt/kWh, where mPt reflects a share of the annual environmental burden of an average global citizen). The solar-powered Two Stage Flash (TSF) also performed well (1.91 mPt/kWh), though with notable trade-offs. Both LVC and TSF reduced global warming-related human health impacts by over 50 % (from 1.45 × 10⁻⁷ to ∼ 7.0 × 10⁻⁸ DALY/kWh, with DALY representing years of healthy life lost due to environmental damage) and significantly lowered fossil resource scarcity (more than 60 %). LVC achieved the lowest fine particulate matter, water consumption, and human toxicity impacts, reduced by 41 %, 63 % and 40 % respectively. However, TSF performs poorly in those categories due to solar infrastructure impacts. Steam and electricity use were major contributors in most systems, with the reboiler and stripper identified as environmental hotspots.

从传统到优化绿色太阳能燃烧后碳捕获的过渡：一个全面的生命周期评估

燃烧后碳捕获（PCC）对于减少化石燃料发电的二氧化碳排放至关重要，但其高能源需求引起了重要的环境问题。本研究使用SimaPro中的ReCiPe 2016 Endpoint (H)方法，评估了天然气联合循环电厂中七种基于二甘醇胺（DGA）的PCC配置的环境性能。配置包括六个完全由植物供电的设计和一个太阳能供电系统。精益蒸汽压缩（LVC）配置实现了最佳的整体性能，与标准配置相比，总影响得分降低了48%（从3.38降到1.75毫/千瓦时，mPt/kWh，其中mPt反映了全球公民平均每年的环境负担份额）。太阳能供电的两级闪光灯（TSF）也表现良好（1.91 mPt/kWh），尽管有明显的折衷。LVC和TSF都将与全球变暖相关的人类健康影响降低了50%以上（从1.45 × 10−7降至~ 7.0 × 10−8 DALY/kWh， DALY代表因环境破坏而损失的健康生命年数），并显著降低了化石资源稀缺性（超过60%）。LVC实现了最低的细颗粒物、水消耗和人体毒性影响，分别减少了41%、63%和40%。然而，由于太阳能基础设施的影响，TSF在这些类别中表现不佳。在大多数系统中，蒸汽和电力的使用是主要的贡献者，再沸器和汽提塔被认为是环境热点。

期刊介绍： Thermal Science and Engineering Progress (TSEP) publishes original, high-quality research articles that span activities ranging from fundamental scientific research and discussion of the more controversial thermodynamic theories, to developments in thermal engineering that are in many instances examples of the way scientists and engineers are addressing the challenges facing a growing population – smart cities and global warming – maximising thermodynamic efficiencies and minimising all heat losses. It is intended that these will be of current relevance and interest to industry, academia and other practitioners. It is evident that many specialised journals in thermal and, to some extent, in fluid disciplines tend to focus on topics that can be classified as fundamental in nature, or are ‘applied’ and near-market. Thermal Science and Engineering Progress will bridge the gap between these two areas, allowing authors to make an easy choice, should they or a journal editor feel that their papers are ‘out of scope’ when considering other journals. The range of topics covered by Thermal Science and Engineering Progress addresses the rapid rate of development being made in thermal transfer processes as they affect traditional fields, and important growth in the topical research areas of aerospace, thermal biological and medical systems, electronics and nano-technologies, renewable energy systems, food production (including agriculture), and the need to minimise man-made thermal impacts on climate change. Review articles on appropriate topics for TSEP are encouraged, although until TSEP is fully established, these will be limited in number. Before submitting such articles, please contact one of the Editors, or a member of the Editorial Advisory Board with an outline of your proposal and your expertise in the area of your review.
