Abstract

The high concentration of polluting emissions, and in particular of CO₂ in the atmosphere, determines the greenhouse effect, therefore it is necessary to reduce its quantity as much as possible. For this reason, a strong commitment is underway to obtain effective technological improvements and to study adequate operational measures. One measure among these may be the oxy-combustion process.

Many researchers have studied this process, its characteristics, and operating conditions but what is not known in the literature is the economic feasibility of a plant employing this technology and its environmental impact. There are few plants powered by oxy-combustion and many of these are still pilot plants, for this reason using Retscreen it was possible to evaluate and optimize the technical and financial feasibility of an oxy-fuel cogeneration plant for a university campus in such a way as to demonstrate the cost-effectiveness and lower environmental impact that an oxy-fuel system causes compared to a traditional system. It was evaluated the return on investment for the cogeneration plant as the economic parameters varied: in almost all cases analyzed the investment turned out to be convenient and the minimum calculated payback time was 2.5 years.

With this software, it was also possible to determine the environmental impact of this technology which corresponds to a reduction of approximately 3700 tons/year of carbon dioxide compared to a traditional type of system. This work will encourage the investors and corporate sector to embrace this alternative technology for decreasing polluting emissions from the process.

全氧燃烧工艺的技术、经济和排放分析

摘要高浓度的污染排放物，特别是大气中的二氧化碳，决定了温室效应，因此有必要尽可能地减少其数量。为此，我们正在大力进行有效的技术改进，并研究适当的操作措施。许多研究人员都对全氧燃烧工艺、其特点和操作条件进行了研究，但文献中并不清楚采用这种技术的工厂的经济可行性及其对环境的影响。因此，使用 Retscreen 可以评估和优化大学校园全氧燃烧热电联产厂的技术和财务可行性，从而证明全氧燃烧系统与传统系统相比具有成本效益，对环境的影响更小。随着经济参数的变化，对热电联产厂的投资回报率进行了评估：在几乎所有分析的情况下，投资都很方便，计算出的最短投资回收期为 2.5 年。通过该软件，还可以确定该技术对环境的影响，与传统系统相比，每年可减少约 3700 吨二氧化碳。这项工作将鼓励投资者和企业部门采用这种替代技术，以减少生产过程中的污染排放。

期刊介绍： Applied Energy serves as a platform for sharing innovations, research, development, and demonstrations in energy conversion, conservation, and sustainable energy systems. The journal covers topics such as optimal energy resource use, environmental pollutant mitigation, and energy process analysis. It welcomes original papers, review articles, technical notes, and letters to the editor. Authors are encouraged to submit manuscripts that bridge the gap between research, development, and implementation. The journal addresses a wide spectrum of topics, including fossil and renewable energy technologies, energy economics, and environmental impacts. Applied Energy also explores modeling and forecasting, conservation strategies, and the social and economic implications of energy policies, including climate change mitigation. It is complemented by the open-access journal Advances in Applied Energy.
