Valorização de CO2 como matéria-prima para a indústria química ou outras – Análise de oportunidades em Portugal tendo em conta a nossa indústria

December 12, 2022

Climate change caused by the emission of greenhouse gases of anthropogenic origin, such as CO2, is a concern that has been promoting a collective effort at an international level to reduce the environmental impact of human activities. On the other hand, carbon is an essential element of most products needed by society, being part of the structure of many chemicals. Therefore, an option under study for the decarbonization of the industry is the recycling of carbon from CO2, i.e., the Capture and Use of CO2. In this way, CO2 will no longer be considered a waste, becoming a raw material. In this dissertation, a survey was made of the ways of recovering CO2 that can be implemented in the Portuguese industry. To this end, the main industrial installations that emit CO2 at national level were identified and the potential users of the captured CO2 were studied to convert it into economically attractive products. Both CO2 sources and possible consumers were located using the QGIS software and the possible relationships between them were studied, considering the distances that separate them and the means of transport accessible on site. It was found that the largest sources of CO2 emissions in Portugal at the Industry level correspond to Oil Refining, Electric and Thermal Energy Production and Cement Production facilities. In this way, the possible CO2 users around these installations were studied in greater detail.
