Abstract

There are approximately 15 million users of system heat in Poland, but unfortunately nearly 70% of the fuel used in heat production is fossil fuel. Therefore, the CO2 emission reduction in the heat production industry is becoming one of the key challenges. City Heat Distribution Enterprise Ltd. in Nowy Sącz (Miejskie Przedsiębiorstwo Energetyki Cieplnej sp. z o.o.) has been conducting a self-financed research and development project entitled The use of algae as carbon dioxide absorbers at MPEC Nowy Sącz. The project deals with postcombustion CO2 capture using Chlorella vulgaris algae. As a result of tests conducted in a 1000 l hermetic container under optimal temperature and light conditions, the recovery of biomass can be performed in weekly cycles, yielding approximately 25 kilograms of biomass per year. Assuming that half of the dry mass of the algae is carbon, it can be said that 240 grams of carbon is bound in one cycle, which, converted to CO2, gives 880 grams of this gas. Our results showed that around 45.8 kilograms of CO2 per year was absorbed. Additionally, it is possible to use waste materials and by-products of technological processes as a nutrient medium for algae

将藻类用作供热行业的二氧化碳吸收剂

波兰约有 1500 万系统供热用户，但不幸的是，近 70% 的供热燃料是化石燃料。因此，减少供热行业的二氧化碳排放量正成为关键挑战之一。位于新松奇的城市供热企业有限公司（Miejskie Przedsiębiorstwo Energetyki Cieplnej sp.该项目涉及利用绿藻进行燃烧后二氧化碳捕集。在最佳温度和光照条件下，在一个 1000 升的密封容器中进行的测试结果表明，生物质的回收可以每周进行一次，每年大约可获得 25 公斤生物质。假设藻类干重的一半是碳，那么在一个周期内可结合 240 克碳，转换成二氧化碳后可产生 880 克二氧化碳气体。我们的研究结果表明，每年可吸收约 45.8 千克二氧化碳。此外，还可以利用废料和技术工艺的副产品作为藻类的营养介质

期刊介绍： Archives of Environmental Protection is the oldest Polish scientific journal of international scope that publishes articles on engineering and environmental protection. The quarterly has been published by the Institute of Environmental Engineering, Polish Academy of Sciences since 1975. The journal has served as a forum for the exchange of views and ideas among scientists. It has become part of scientific life in Poland and abroad. The quarterly publishes the results of research and scientific inquiries by best specialists hereby becoming an important pillar of science. The journal facilitates better understanding of environmental risks to humans and ecosystems and it also shows the methods for their analysis as well as trends in the search of effective solutions to minimize these risks.
