Abstract
The latest IPCC report shows a scenario in which replacing fossil fuels and improving the efficiency of energy systems may not be enough to ensure an increase in the global average temperature of less than 1.5 °C by 2040. One of the challenges of the 21st century is to reduce emissions and the resulting concentration of CO2 in the atmosphere and, at the same time, carry out the energy transition without major damage to the world economy. Carbon Capture, Use, and Storage (CCUS) can be the main route to achieving Greenhouse Gas (GHG) reduction targets. This work presents a computational simulation of the flue gas flow of combustion gases from the burning of fossil fuels such as natural gas and liquefied petroleum gas, which cross pipelines of porous materials in an arrangement with a constructal design. The pipelines are interspersed in constructs which gradually increase in size along the flow to capture carbon. A constructal ratio between the pressure drop and the rate of the capture reaction is also considered. To predict types of hypothetical materials efficient for carbon capture, in this simulation, a parametric evaluation is carried out considering the specific mass of the material, its porosity, the average diameter of the pores, and the molecular diffusion coefficient. Given that, an important objective of this study is the development of carbon capture devices, an analysis of the results obtained when employing advanced carbon capture materials (MACC) is made in this work against those obtained when hypothetical efficient carbon capture materials are being considered. The minimum energy required for the carbon capture process is also evaluated, as well as the capture cost per ton of CO2.
